Great rundown. I'm currently on the hunt to get the controller to stop flashing E4. I cleaned the filters, cleaned the evaporator and condensor. And I've performed a reset at the control. Next step, turn off the 50-amp and see if that resets the unit on the roof. We appreciate what you do John.
Glad the video was helpful. By "performed a reset at the controller" do you mean you removed the thermostat faceplate, waited 10 seconds or so, then put the faceplate back on?
@@JohnMarucci no, I powered it off, held the mode and the up for 3 seconds until I got 2 lines. Then hit mode again, and it turned back off. Then when I turn it back on the Temp settings went back to default.

I just purchased my rv with this setup. My AC set on low will occasionally just shut off in the middle of the night. Sometimes it’s just for a couple seconds, then turn back on, ramp up the fan speed to high, then back to low, and continue running. Or, the ac will just shut off completely. Any ideas. The rv is brand new and used only two nights. I am certain that the setting is NOT on auto. Thank you!
@@JohnMarucci I tried resetting the unit by pushing the mode and up bottom as advised by a domestic tech. So…is another method, to literally remove the face plate, and simply put it back on? The tech from dometic suspects a control board issue. It’s under warranty, but inconsistent. In order for it to be covered a tech must diagnose it. Problem is, it doesn’t present the problem all the time.
I’m glad we have a dometic, just wish they put an upgrade thermostat that at least displays the temperature all the time. It’s silly you have to have it off, touch the mode button then up button or whatever, can’t remember exactly, just irritating from what I recall? Any thermostat replacement recommendations for simple but more normal?
I see that this video is 3 years old, so I don't know if I'll get a response. You really helped me diagnose my problem, it's the faceplate. Is it possible to buy just the faceplate, or do you have to replace the entire thermostat? If you have part numbers, that would be great! Thank you, Sir!
Thanks for all the valuable info. I’m getting and E4 error code in my 172 2018 R Pod. It was working fine. One day and not the next. It was very windy where I was parked . Is there an easy fix for this?

Hey John. I have replaced the original one. My problem is the unit will keep getting cold way past the setting. The unit will no turn off. What do you think.
We have same problem of therstat works eratic temp delays over +-5 degrees so constantly cabin temp drops below 68, then heats to over 76 when furnace set at 74 causing cabin left very cold, then roasting. Could some contacts need cleaning? Or way to adjust the amount of variance? Then other times works well. What's causing eratic delays and run times?
My ac shuts off even with fan on low once i set the temp below 68. How can i make the a/c run continuously as you explained at 64 degrees F? Thank you for the video! Best wishes!
Hi Jhon, i'm new to the channel. 🙋🏼 I'm renting an RV with this kind of unit. Trying to set the furnace I'm feeling hot air coming out of the bottom vents but cold coming out from the ones on the ceiling. If this normal? We are getting chilly here around 30 Fahrenheit and can't handle the cold air coming from the top. I tried to set the thermostat to low-furnece 72 Fahrenheit and can't make it happen. Any advice will help and many thanks.
@@JohnMarucci I have it low furnace 73 degrees. And still doing the same. Cold air from the top. My wife told me, the first date there's no air coming from the top, just the bottom vents, could that be possible?
Sounds like it may not be getting 12v volt power. Try double checking that all your fuses are working. I'm assuming you have 12 volt battery power to the rig and that your battery is in good shape.
All fuses seem to be good. However, the 7.5 furnace fuse doesn’t light up when I take it out, like the other fuses. It’s hooked up to two batteries which are new and hooked up to shore power as well. Thanks @@JohnMarucci
John, I have an 11 year old Montana with dual ac. The thermostat is driving me crazy. Last year it worked, this year it does not do as commanded. Any idea how I can get someone to check it and repair/replace as needed? Ie: do heating/ac guys work on these RV thermostats?
@@JohnMarucci No, I have not. I just now tried and there are no screws to loosen. Apparently it is suppose to pop off? Is that correct? I’m s little timid about being aggressive and plying it with screwdrivers to pop it off. If I mess it up……I’m in big trouble with summer coming! If it pops off, I may have a repair guy do it.
Take a look at the video where I replaced the thermostat for a reference. The faceplate should pop off, revealing screws underneath: Dometic Thermostat Replacement - Step-By-Step ruclips.net/video/wVsA5_4M6nk/видео.html
The link is for the entire thermostat, not just the faceplate. I am not sure that you can find the faceplate alone now. Here is the link that is in the video description (which you likely already tried): amzn.to/3DcP5gj
Great informative video John, Now I know that my furnace only works on propane! Your explanation of how the touch feature works-or doesn’t work, was revealing. I subscribed! Mike 2017 Work and Play Toyhauler.
Glad the video was helpful! Many more videos if interested. This link has a searchable index of every video we’ve published: johnmarucci.com/video-index-mobile/
I don't know of any electric furnaces in RVs. I do use an electric foot heater fairly regularly when plugged into shore power to keep propane usage down.
The problem I had with both this style and the old push button one over winter they would quit working. When the ac was on and cooled down to temp, you would have shut off. Then back on to get the ac to turn back on. I had to put a new one in every year. After 5 new thermostats I ended up going with a Micro Air thermostat.
Low fan mode should kick the fan on. If it isn't working, try resetting the unit by removing the faceplate, waiting 15 seconds, then putting thr faceplate back on.
The prior owner of my Puma had one of these installed. The first thing I tried to do was *push* the buttons. After I figured out you didn't have to I kind of like the touch function. Thank you for the informative video. After watching this video I was thinking it might be a good idea to buy an extra face plate to keep in the trailer just in case.
Having an extra faceplate isn't a bad idea at all. Once the small foam pieces at the buttons in the faceplate get compacted the buttons tend to fail occasionally. Thanks!
@John Marucci Now that you've had this thermostat for a while, would you buy it again? I am looking to upgrade my analog thermostat, and was thinking about the Dometic thermostat, would you recommend this product? Thank you.
Rick, after replacing the first one, my current one has worked flawlessly. I just remember to never push on the buttons but only tap lightly and it has been fine. I would buy it again. Thanks!
@@JohnMarucci Perfect!!! You just helped me make my decision. I am going to buy it. Thank you so much in helping me make my decision. Oh, one more thing. This does have a high and low fan for the A/C, yes? I have a Mach A/C 15,000 BTU ducted in my 32 foot travel trailer.
@@rickrangel Yep, it has the three fan speeds, Low, High, and Auto. Works well if you want to leave it on Low overnight for ambient noise. Auto will turn the A/C on and off and can wake me up at times on a hot evening.
@@JohnMarucci Hi John, I went to your Amazon Store to buy the thermostat, buy I couldn't find it. Can you provide with a link, this way I could help you out since you've been very helpful? I know it may not be much, but every penny helps now-a-days.
Hey man, I have this same thermostat and when I have it set to auto it doesn’t cycle sometimes and let’s it get too hot in the cabin until I do a reset on the thermostat. Any idea what the issue could be?
I am not sure what the issue would be. I replaced mine recently with my furnace issues. It's a pretty easy job to fully replace it if you decide to go that way. I'll have a video out on replacing it in a couple of weeks.
I'm getting a e4 code and only able to run the fan in keystone Montana.... the rear ac has zero issues.... should I check for corrosion on the wires ... clean them maybe?
It looks to be an open circuit or out of range Outdoor Temperature Sensor on select models. Here is the link to where I am seeing the error code: www.dometic.com/assets/46/43/operating%20manual_64643.pdf
Not that I know of. The cheapest I see a full replacement thermostat is about $40 at RV Parts Country but I have never ordered from them, so I can't vouch for them.
John, Hope you can help. I was cleaning after my husband had COVID and wiped the Dometic RV Thermostat cause I know he was using it a lot when he was sick. When I did this I changed it from Fahrenheit to Celsius. We can't figure out how to get it back. Can you help? Hope so.
hey john, me and my mom just got a new rv with this thermostat. the problem is, everytime we turn it on, we hear is click but the fan never kicks on. any help with this?
Thanks John for the great video. Have you had any issues of the unit cycling on and off and the coils freezing. Curious if you had any suggestions for that on hot humid days.
Sometimes if it is really hot and humid, the coils can ice up if the unit is running a long time. Basically you may need to let it thaw out before turning it back on. You can run the fan a while and keep the compressor off to expedite the melt. If the unit is older or you have been in areas with lots of debris in the air, you may need to clean the coils (which should be done regularly) and this can improve performance. I had a bunch of milkweed in my coils recently from a trip in Michigan in June that junked up my coils. Makes a difference in performance if you keep them clean. Thanks!
Mine isn’t very accurate either, but 5 degrees seems a large variance. I personally would either ask on some of the forums to see if others have a solution or call Dometic directly.
@@JohnMarucci I have it set at 55° now on high and it will cut off on low or auto much quicker the real and temperature is 71°.. I will likely call then tomorrow and see what they think.. thank you for the response!
Ac went out put new fan motor , capacitor and even new wall controller just like this one in this video worked great for about an hour cycling on and off with desired temp setting blows cold but now it just continuously runs i have to use breaker to give it a rest setting is on auto have any ideas???
I had the problem with the touch sensitivity of the thermostat from when I first got my new Rpod. The RV tech showed me how to fix it by pulling out the foam blocks slightly to decompress them with a tweezer being careful not to tear them. Once he did that I've been careful not to push the buttons and haven't had a problem since.
Great point Mike. Mine was too far gone. For those who catch it soon enough, they can save the money on a new faceplate with your solution. Thanks again!
I figured out if I take the face plate off, I can do everything and then put the face plate back on, which actually might be great for when kids or guest are around, but I would still like to know how to fix a properly
I had to replace the entire unit with a new one. I do have a video on the process if you go there: ruclips.net/video/wVsA5_4M6nk/видео.htmlsi=M3Ofq2-la6yykkqS
HI John. I have a2016 Rp 179. I'm baffled about the AC overhead controls verses the thermostat on the wall. I'd like to set the AC while away from RV but when I move thermostat lever it only operates the furnace in heat mode. It's a 50 to 90 degree thermostat.. I'm missing something here. Help.
I am not certain what would be the best replacement. If you do try a different brand, be aware that not all wiring may be aligned for a simple replacement. I put a new cover on mine and haven't had any issues since. All the best!
I only replaced the faceplate. It took less than a minute. I would imagine that if you replaced the entire thermostat, that it may take up to an hour to ensure you connect everything correctly and test it out well. If you do a full replacement, you may want a more detailed video showing each wire being reconnected. Thanks!
I am assuming that you are plugged into shore power (30 amp) and that all your wall outlets are working fine in the RV? If so, check your fuse box to see if something tripped the A/C fuse. Also, can you get the fan to run on low or high from the thermostat? If you can, then the A/C unit is likely getting power, since the fan that runs is in the A/C unit. Let me know.
That it is odd. I would think something is blocked but if you are getting forced air from all the registers I’m not sure. I’d personally start at the furnace to see how the runs are hooked up. I have a video about a furnace repair if you need to take a look for references: ruclips.net/video/z-z_i8ddygA/видео.htmlsi=TDOWUUIk0q1Z36yE
Tim, I picked up a new unit on Amazon and just used the screen from it. So I now have a spare unit if needed. This black one may not be identical to the white ones in the Pod. Here is a link to the unit on my store if interested: amzn.to/3lLahQa
Thanks John! Also, I never used the feature of over-riding the auto-fan with the low fan setting at night. Every time that fan kicks on I wake up! With the continued low fan I may just sleep through the night now! We experienced our first flat tire on the Pod on Monday during our trip home from Spokane. Thanks to the PMS , we stopped in time with the warning buzzer to save us from having a blow-out. Now I feel much more secure with the display screen showing air pressure and temperatures while towing the Pod.
Tim, glad you were able to take care of the flat tire before it caused any damage via a blow out! I use my TPMS on every trip and it is has been a great knowing the psi and tire temps as I am traveling. All the best!
I did own the R-Pod 179 at the time but this video was taped in my 2020 Keystone Bullet. Both had similar thermostats. I had two trailers for a couple of years. Sold the R-Pod May 2022.
Hey John, I've already watched this video. It's different than the set up I have. Wish I could send you a picture of what I have. My thermostat resembles the old style in home type with control setting lever on top that you move left or right. My question also is. Does it operate the overhead AC unit that has the on off control knobs on unit. I fail to see how the thermostat controls the overhead. ugggh. Thanks again for any insight. Jody
I am not sure of your set up. It seems like your thermostat only controls your furnace. So the video does not apply. Likely your A/C has controls on it to adjust fan speed and cooler temps. You will have to play with it to see how it works. Thanks!
I have an issue....I can change the settings but the fan on low or high won't come on....it does not do this all the time, but is aggravating when it doe not come on for ambiance noise to sleep. Please help
Margaret, I haven’t heard of this happening before. I do know that the fan is part of the A/C unit in the ceiling. It could be a loose connection based on your comment about the intermittent nature of the occurrence. You may want to look up to see if there is a mobile RV tech nearby. I would likely ask on my trailer brands Facebook group next, to see if anyone else has suggestions. Thanks.
If you leave the AC on auto how often does the AC cycle on or at what temp does it happen? I had mine set on auto and it got to temp then turned itself off and the temp was 10 degrees higher and it never came back on.
Cliff, sounds like the thermostat isn't calibrated well as 10 degrees is a pretty big delta. Mine usually kicks on when it gets about the temps set and sometimes stays on pretty long after it gets below the required cooling temp (3-4 degrees). I believe there is a two-year warranty on the thermostat and would think you could call Dometic (or your dealer) to get a replacement if it is not working properly. Thanks.
@@JohnMarucci I'm having the same problem, but maybe you have given me an answer. I set the AC to a specific temperature and it seems the AC runs and won't cut off. How do you calibrate the Thermostat? I was randomly pressing buttons together and it did come up with something like "---", "D1" and "D2" being displayed.
Mikki, unfortunately, I am not familiar with your model. There are some basic things to try. First, flip the breaker for the a/c unit off then back on at the fuse box. If that doesn't do it, then you can fully remove the dometic thermostat face plate and then put it back on. You'll need to wait a minute afterward, then the thermostat should be reset. If you are not comfortable doing either of these, you may consider a service call to your RV dealer or a service tech. Thanks!
@@JohnMarucci thanks so much!!! I had cleaned the filter and cover which wasnt bad at all Then i had flipped the ac breaker off then back on Just took off face plate and put it back on....seems to have fixed it!! My husband is gonna think im a genius thanks again!!!!🙂
It probably is possible. I haven’t done it but there may be owners who have. You can try the Keystone RV Facebook group and you may find someone who has done this. Thanks!
Thank you for this very helpful video. I only wish my RV sales guy would have explained these simple features rather than rambling on about other stuff.
My AC is 15,000 btu and my generator is a q6500 briggs and stratton inverter generator. It states it has a 5000 watt normal running capacity. This generator will not run my air conditioner. I may have to install a soft start in my unit. Is this normal but my generator is so massive. Thanks for posting.

The link is for the entire thermostat, not just the faceplate. I am not sure that you can find the faceplate alone now. Here is the link that is in the video description (which you likely already tried): amzn.to/3DcP5gj
Great informative video John, Now I know that my furnace only works on propane! Your explanation of how the touch feature works-or doesn’t work, was revealing. I subscribed!

Glad the video was helpful! Many more videos if interested. This link has a searchable index of every video we’ve published: johnmarucci.com/video-index-mobile/
This is a dumb question, I’m sure, but can the furnace run on electric power if you’re out of propane? Thx!
I don't know of any electric furnaces in RVs. I do use an electric foot heater fairly regularly when plugged into shore power to keep propane usage down.
Mike can these thermostats be replaced with a better upgrade?
The problem I had with both this style and the old push button one over winter they would quit working. When the ac was on and cooled down to temp, you would have shut off. Then back on to get the ac to turn back on. I had to put a new one in every year. After 5 new thermostats I ended up going with a Micro Air thermostat.
Sounds like a good idea. Hopefully hooking it up was straight forward?
@@JohnMarucci very easy same wiring as the old one.
Having the same problem
Does the thermostat work when the unit is in the low mode. ???? Thanks
Low fan mode should kick the fan on. If it isn't working, try resetting the unit by removing the faceplate, waiting 15 seconds, then putting thr faceplate back on.
Well your video answered my issue on a 2018 FR vengeance I just bought. I'm probably going to upgrade it to a smart thermostat.
Sounds good, glad the video was helpful!
This was VERY helpful because, I don’t know how to produce heat
Good to hear. Glad the video was helpful!
The prior owner of my Puma had one of these installed. The first thing I tried to do was *push* the buttons. After I figured out you didn't have to I kind of like the touch function. Thank you for the informative video. After watching this video I was thinking it might be a good idea to buy an extra face plate to keep in the trailer just in case.
Having an extra faceplate isn't a bad idea at all. Once the small foam pieces at the buttons in the faceplate get compacted the buttons tend to fail occasionally. Thanks!
Hi John, this is great. My 82 yr old dad has issues with this, can it be exchanged with a dometic analog thermostat?
I don’t know what if any analog thermostat can be switched out for this one. You may want to ask a local RV dealer or mobile RV tech. Thanks!
@John Marucci Now that you've had this thermostat for a while, would you buy it again? I am looking to upgrade my analog thermostat, and was thinking about the Dometic thermostat, would you recommend this product? Thank you.
Rick, after replacing the first one, my current one has worked flawlessly. I just remember to never push on the buttons but only tap lightly and it has been fine. I would buy it again. Thanks!
@@JohnMarucci Perfect!!! You just helped me make my decision. I am going to buy it. Thank you so much in helping me make my decision. Oh, one more thing. This does have a high and low fan for the A/C, yes? I have a Mach A/C 15,000 BTU ducted in my 32 foot travel trailer.
@@rickrangel Yep, it has the three fan speeds, Low, High, and Auto. Works well if you want to leave it on Low overnight for ambient noise. Auto will turn the A/C on and off and can wake me up at times on a hot evening.
@@JohnMarucci Hi John, I went to your Amazon Store to buy the thermostat, buy I couldn't find it. Can you provide with a link, this way I could help you out since you've been very helpful? I know it may not be much, but every penny helps now-a-days.
@@rickrangel This should be the link: amzn.to/3wPcBx1
Hey John, any insits on the unit freezing the coils when the ac is on. No matter temperature or fan seating (auto,high or, low)
Sounds like a coolant leak or blocked air flow to the unit. Here is an article on the subject: www.petro.com/resource-center/why-ac-freezing-up
Hey man, I have this same thermostat and when I have it set to auto it doesn’t cycle sometimes and let’s it get too hot in the cabin until I do a reset on the thermostat. Any idea what the issue could be?
I am not sure what the issue would be. I replaced mine recently with my furnace issues. It's a pretty easy job to fully replace it if you decide to go that way. I'll have a video out on replacing it in a couple of weeks.
I'm getting a e4 code and only able to run the fan in keystone Montana.... the rear ac has zero issues.... should I check for corrosion on the wires ... clean them maybe?
It looks to be an open circuit or out of range Outdoor Temperature Sensor on select models. Here is the link to where I am seeing the error code: www.dometic.com/assets/46/43/operating%20manual_64643.pdf
John is there a part number for just the face plate? I sure could use one. Thanks.
Not that I know of. The cheapest I see a full replacement thermostat is about $40 at RV Parts Country but I have never ordered from them, so I can't vouch for them.
Excellent. Thanks John you were very informative.
Thanks, glad the video was helpful!
Love it! I should have looked this up sooner! I looked at 6 rv with system and every owner was pissed about it but to lazy to investigate!
Glad the video was helpful!
John,
Hope you can help. I was cleaning after my husband had COVID and wiped the Dometic RV Thermostat cause I know he was using it a lot when he was sick. When I did this I changed it from Fahrenheit to Celsius. We can't figure out how to get it back. Can you help? Hope so.
If you push the up and down arrows at the same, it should toggle the display between Fahrenheit and Celsius.
Great video John. Would you happen to have a link for the replacement faceplate? Thank you.
I’m pretty sure they don’t sell the faceplate separately. If you do find one sold separately, please let me know.
hey john, me and my mom just got a new rv with this thermostat. the problem is, everytime we turn it on, we hear is click but the fan never kicks on. any help with this?
Try carefully prying off the faceplate waiting 20 seconds then putting the faceplate back on. It should reset the unit.
Very informative video!!! Thanks
Glad it was helpful!
Thanks John for the great video. Have you had any issues of the unit cycling on and off and the coils freezing. Curious if you had any suggestions for that on hot humid days.
Sometimes if it is really hot and humid, the coils can ice up if the unit is running a long time. Basically you may need to let it thaw out before turning it back on. You can run the fan a while and keep the compressor off to expedite the melt. If the unit is older or you have been in areas with lots of debris in the air, you may need to clean the coils (which should be done regularly) and this can improve performance. I had a bunch of milkweed in my coils recently from a trip in Michigan in June that junked up my coils. Makes a difference in performance if you keep them clean. Thanks!
My auto doesn’t seem to work regularly. I can set it to 70° on ac and it will get well above that (75°+) when it kicks on.. any suggestions?
Mine isn’t very accurate either, but 5 degrees seems a large variance. I personally would either ask on some of the forums to see if others have a solution or call Dometic directly.
@@JohnMarucci I have it set at 55° now on high and it will cut off on low or auto much quicker the real and temperature is 71°.. I will likely call then tomorrow and see what they think.. thank you for the response!
Where did you acquire the new faceplate. I can only find complete units.
Unfortunately, I had to buy the entire unit.
Very helpful!! Thank you very much
Glad it was helpful!
Ac went out put new fan motor , capacitor and even new wall controller just like this one in this video worked great for about an hour cycling on and off with desired temp setting blows cold but now it just continuously runs i have to use breaker to give it a rest setting is on auto have any ideas???
I am not an HVAC expert. Not sure why it is doing what you are experiencing. Sounds like you need a service call to me.
@@JohnMarucci thanks👍
Thanks great info
Glad it was helpful!
THANKS!! Great tips!!👍🏻🙌🏻
Glad the video was helpful!
Did not know that about the touch screen thanks for the tip! also your videos on the Rpods help me sell ours this past month
Glad to hear it. Thanks for the comment!
I have a domestic on my boat and it keeps changing itself to heat. How do I get back to air cold?
Try removing the faceplate and reseating it. This should reset the unit.
I had the problem with the touch sensitivity of the thermostat from when I first got my new Rpod. The RV tech showed me how to fix it by pulling out the foam blocks slightly to decompress them with a tweezer being careful not to tear them. Once he did that I've been careful not to push the buttons and haven't had a problem since.
Great point Mike. Mine was too far gone. For those who catch it soon enough, they can save the money on a new faceplate with your solution. Thanks again!
Mike my unit wont turn off do you think doing what you said would work?
I had the same issue and put a little bit of aluminum foil behind the foam to fill the gap. Works great now!
Hi John, I need the QR code to set up the blue tooth on this same thermostat. do You have an code that you could send me?
Sorry, I don’t have a QR code as my unit doesn’t have Bluetooth.
I figured out if I take the face plate off, I can do everything and then put the face plate back on, which actually might be great for when kids or guest are around, but I would still like to know how to fix a properly
I had to replace the entire unit with a new one. I do have a video on the process if you go there: ruclips.net/video/wVsA5_4M6nk/видео.htmlsi=M3Ofq2-la6yykkqS
HI John. I have a2016 Rp 179. I'm baffled about the AC overhead controls verses the thermostat on the wall. I'd like to set the AC while away from RV but when I move thermostat lever it only operates the furnace in heat mode. It's a 50 to 90 degree thermostat.. I'm missing something here. Help.
It sounds like you do not have the Dometic thermostat talked about in this video but instead separate furnace and A/C controls.
I been researching getting the Brisk 2 13.5k and putting a Thermostat in with it though I wonder if there is another Thermostat that can be used. ?
I am not certain what would be the best replacement. If you do try a different brand, be aware that not all wiring may be aligned for a simple replacement. I put a new cover on mine and haven't had any issues since. All the best!
Great info! How long should it take to replace this domestic thermostat?
I only replaced the faceplate. It took less than a minute. I would imagine that if you replaced the entire thermostat, that it may take up to an hour to ensure you connect everything correctly and test it out well. If you do a full replacement, you may want a more detailed video showing each wire being reconnected. Thanks!
Great Video!
Glad you enjoyed it!
My dometic AC with the same controller simply stopped working this morning, any insight on what might be going on.
I am assuming that you are plugged into shore power (30 amp) and that all your wall outlets are working fine in the RV? If so, check your fuse box to see if something tripped the A/C fuse. Also, can you get the fan to run on low or high from the thermostat? If you can, then the A/C unit is likely getting power, since the fan that runs is in the A/C unit. Let me know.
Only the vent in the bed room section produces heat all the rest just blow room temperature any tips
That it is odd. I would think something is blocked but if you are getting forced air from all the registers I’m not sure. I’d personally start at the furnace to see how the runs are hooked up. I have a video about a furnace repair if you need to take a look for references: ruclips.net/video/z-z_i8ddygA/видео.htmlsi=TDOWUUIk0q1Z36yE
John we have an issue with the ac unit. I need to know how to change the thermostat from Celsius back to Fahrenheit
John, if you hit the up and down arrows simultaneously it should toggle between Fahrenheit and Celsius.
What does E4 code mean? Can’t find any information. Thank you.
It is at the bottom of this doc from my website: johnmarucci.com/wp-content/uploads/2022/05/Dometic-Thermostat-Guide-2.pdf
Thank you very much.
My touch screen has been abused since we bought the Pod. Luckily it still works! Where did you buy a replacement touch screen John?
Tim, I picked up a new unit on Amazon and just used the screen from it. So I now have a spare unit if needed. This black one may not be identical to the white ones in the Pod. Here is a link to the unit on my store if interested: amzn.to/3lLahQa
Thanks John! Also, I never used the feature of over-riding the auto-fan with the low fan setting at night. Every time that fan kicks on I wake up! With the continued low fan I may just sleep through the night now! We experienced our first flat tire on the Pod on Monday during our trip home from Spokane. Thanks to the PMS , we stopped in time with the warning buzzer to save us from having a blow-out. Now I feel much more secure with the display screen showing air pressure and temperatures while towing the Pod.
Tim, glad you were able to take care of the flat tire before it caused any damage via a blow out! I use my TPMS on every trip and it is has been a great knowing the psi and tire temps as I am traveling. All the best!
John this video was made when you owned the rpod 179 correct?
I did own the R-Pod 179 at the time but this video was taped in my 2020 Keystone Bullet. Both had similar thermostats. I had two trailers for a couple of years. Sold the R-Pod May 2022.
@John Marucci if it's OK with you, I have a few questions regarding this. What is the best way to contact you?
You can email me at: john@johnmarucci.com
Thanks god bless
Thanks!
You was so helpful. Thank you so much.
Glad it was helpful!
Bless you, Sir. Now I know.
Glad the video was helpful!
Thank you so much! I had accidently hit both up and down arrows and my unit was set to celcius.
Glad the video was helpful!
Yep, me too.
Hey John, I've already watched this video. It's different than the set up I have. Wish I could send you a picture of what I have. My thermostat resembles the old style in home type with control setting lever on top that you move left or right. My question also is. Does it operate the overhead AC unit that has the on off control knobs on unit. I fail to see how the thermostat controls the overhead. ugggh. Thanks again for any insight. Jody
I am not sure of your set up. It seems like your thermostat only controls your furnace. So the video does not apply. Likely your A/C has controls on it to adjust fan speed and cooler temps. You will have to play with it to see how it works. Thanks!
I have an issue....I can change the settings but the fan on low or high won't come on....it does not do this all the time, but is aggravating when it doe not come on for ambiance noise to sleep. Please help
Margaret, I haven’t heard of this happening before. I do know that the fan is part of the A/C unit in the ceiling. It could be a loose connection based on your comment about the intermittent nature of the occurrence. You may want to look up to see if there is a mobile RV tech nearby. I would likely ask on my trailer brands Facebook group next, to see if anyone else has suggestions. Thanks.
If you leave the AC on auto how often does the AC cycle on or at what temp does it happen? I had mine set on auto and it got to temp then turned itself off and the temp was 10 degrees higher and it never came back on.
Cliff, sounds like the thermostat isn't calibrated well as 10 degrees is a pretty big delta. Mine usually kicks on when it gets about the temps set and sometimes stays on pretty long after it gets below the required cooling temp (3-4 degrees). I believe there is a two-year warranty on the thermostat and would think you could call Dometic (or your dealer) to get a replacement if it is not working properly. Thanks.
@@JohnMarucci I'm having the same problem, but maybe you have given me an answer. I set the AC to a specific temperature and it seems the AC runs and won't cut off. How do you calibrate the Thermostat?
I was randomly pressing buttons together and it did come up with something like "---", "D1" and "D2" being displayed.
Wow thank you!
I can not get the thermostat to turn on do I need to replace the screen
Are you certain that you have 12-volt power to the RV and that your fuse is working?
Mine has a Bluetooth icon....what is the benefit of having that?
Not sure, mine doesn’t have this. It may be for an app that came with the RV.
What about the Micro-Air EasyTouch RV Wifi thermostat? It's a drop in replacement for this with the 351 model. Like the NEST for the RV.
Sound interesting. Do you have a link to a video review?
Thanks John
Glad to help!
Where is my ac reset button on 2020 grey wolf limited?? Do you happen to know??
Mikki, unfortunately, I am not familiar with your model. There are some basic things to try. First, flip the breaker for the a/c unit off then back on at the fuse box. If that doesn't do it, then you can fully remove the dometic thermostat face plate and then put it back on. You'll need to wait a minute afterward, then the thermostat should be reset. If you are not comfortable doing either of these, you may consider a service call to your RV dealer or a service tech. Thanks!
@@JohnMarucci thanks so much!!! I had cleaned the filter and cover which wasnt bad at all
Then i had flipped the ac breaker off then back on
Just took off face plate and put it back on....seems to have fixed it!!
My husband is gonna think im a genius thanks again!!!!🙂
Is it possible to replace this thermostat and go back to a analog thermostat?
It probably is possible. I haven’t done it but there may be owners who have. You can try the Keystone RV Facebook group and you may find someone who has done this. Thanks!
Thank you for this very helpful video. I only wish my RV sales guy would have explained these simple features rather than rambling on about other stuff.
Glad it was helpful!
My AC is 15,000 btu and my generator is a q6500 briggs and stratton inverter generator. It states it has a 5000 watt normal running capacity. This generator will not run my air conditioner. I may have to install a soft start in my unit. Is this normal but my generator is so massive. Thanks for posting.
Likely, the 15k BTU unit is drawing much more power upon start-up than listed. I would think a soft-start should solve for this. Thanks!
Where can I find the face plate? Not the whole thermostat
I am only seeing the full thermostat available for sale. If you do find out where a faceplate can be purchased, please let me know. Thanks.
Great video. Thanks!!!
