Designed for quick and simple application
Refrigerator Control Board Kit; Use With Dometic DMH1072/ DM2862/ DM2852/ DM2652 Refrigerators. With Power Board: Yes
Dometic provides branded solutions for mobile living in the areas of Climate, Hygiene and Sanitation, Food and Beverage, Power and Control and Safety and Security. Our mission is to make the mobile life easy.This is a replacement lower control board for select Dometic gas absorption refrigerators. The lower control board is the main circuit board on the refrigerator and controls the ignition of the propane and the power to the AC element. This item is compatible with the following models: DM2652; DM2662; DM2663; DM2852; DM2862; DM3862; NDM1062; NDR1062; RM2351; RM2354; RM2451; RM2454; RM2551; RM2554; RM2620; RM2652; RM2662; RM2820; RM2852; RM2862.
Several DIY online videos suggest that if your Frig is not working on AC and you have check the power supply, the glass fuses and heating element, than its likely that the lower control board is bad. So I went this route and purchase a new lower control board, but unfortunately it did not solve the problem. I was fortunate that Amazon allow this item to be returned for a refund. I was pretty much resigned to running the frig off LP gas until I learned that the upper control board could cause this issue. So I purchased a upper control board and it solved the problem. My frig now runs off of AC or gas, depending on if the AC is available. Therefore, if you are have a similar problem with your RV refrigerator, know that replacing the upper control board may solved your problem.

If your cooling system is leaking, that is a big issue and requires the refrigerator to be removed. As long as that is not the issue, then you should be able to fix it by replacing either fuses/breakers or a control board. Parts available here: amzn.to/3z5ssWE
This is what we ended up doing in our RV for the fridge: ruclips.net/video/mxYPcA0Mvu4/видео.html
That pesky little button!!!! I never would've found that without this video, saved me today, thank you!
Glad I could help!
Same here. Lights on the control panel and inside working and after checking power to the leads it was the little button. Thanks a million!!
What a great video. Very clear and concise. With few exceptions, your instructions are accompanied by very clear views of what your probe is actually touching. You are slow speaking and methodical in your trouble shooting. Fantastic!!
Thank you.
Yes! This is a great video and I couldn't be more thankful that I found it in a pinch. My refrigerator stopped working and he led me right to the fuse. So so thankful.
So so thankful that I found your video. Living in my RV in the heat of the summer and my refrigerator stopped working. You led me right to the fuse! I pulled another fuse to replace it immediately from something that I wasn't using. Thank you so much you saved me today. Great video!!!! I'm saving this in case I need more tips and tricks.
Glad this could help. Now to find out why the fuse blew in the first place.
We have been avoiding the fridge issue for 8 months 🫣 very skery... $2.50 /day for ice=$500-$600😮 and now I see the black 🖤 frigging button that looks like a muddobbers nest material?!?!!😫
Thanks for making it look so simple
WOW! Your explanations are very clear but your photography is excellent!!! For the first time I could actually see what you were describing. No one else is as clear. TY
Glad it was helpful! Thank you.
One of the most informative videos I’ve ever see. The best part is when you posted on the screen “ If you get shocked, it’s your fault”. LOL
Thank you. I was hoping it would help someone.
I agree one of the best rv videos for troubleshooting and super easy to understand. great video
Dude this is an awesome video, I really appreciate the way you walk through the use of the multimeter because I’m a noob with a multimeter but I was able to pinpoint the problem and as long as that little switch that popped out doesn’t continue popping out, I’ll be golden! Thank you again
Glad it helped. Good luck.
Thank you so much. I was about to buy s new fridge and decided to look at RUclips. Your video popped up and I followed along. Great instructions!!! My fridge turned back on 😁 and I dont have any of the residue. I unplugged my trailer with the fridge on and I think that must have been the reason. It's still running 24 hours later. Thank you thank you. Your the man!!
Glad I could help! Hope it was just that issue. Take care.
I think I blew my fuse by unplugging my trailer before turning the fridge off. Now I know better. Living in an RV and learning every step of the way. This is such a great video. He led me right to the fuse thank goodness
My thermal switch tripped. No evidence of any leaks. Called Dometic and talked to them and they said it should be OK. This was a great video. Very detailed and helpful. Thank you.
Glad it was helpful! Thank you.
This was so helpful. I goofed up and broke the tab of that little thermal fuse on the boiler when unhooking the wires so I have to replace it now but hopefully that will be the only problem. Thank you for going through all that troubleshooting the way u did. Super helpful and informative 👍
Glad it helped! Thanks for watching.
Super helpful, saved a trip to the service center. Not the same issue as yours, but your troubleshooting steps caught our issue along the way. The detail you went into helped so much
I am glad it was helpful and happy it was not my issue.
Thank you so much for producing this video! Even after a couple of years it came in handy for me since my Dometic frig in my Jayco fifth wheel all of a sudden stopped working. I started the troubleshooting the electrical system AC first and then found out that I didn't have any DC going to the fridge. Turned out that a fuse was blown (doing its job). So just replaced it and it started right up.
Glad it was just a fuse.
Excellent explanation! I appreciate the way you went through each step. I know nothing about electrical but the way you explained and did the trouble shooting I am confident that I will be able to find the issue. Thank you so very much!
Good luck. Hope it's minor. Thanks.
Thank you for trying I appreciate you for helping.
That switch ended up being my issue! Pressed it back in and now it’s working. I don’t see any leaks but will keep an eye on it. Thanks for the video!!
Glad I could help. If it blows again, I would have it checked. Good luck to you.
Thank you for the well explained video on the trouble shooting problems. We need more of this sort in here!.
Thank you. Glad it was helpful.
Thank you SO MUCH. We just arrived at our campsite for the next week and it’s 98° at 8 PM. The refrigerator wasn’t working and it turned out to be the same little black sensor switch. Amazing! Thank you!
Glad it helped. I know the feeling.
This is a fantastic video that helped lead me to my problem. I had no power to the refrigerator. I followed your advice up to the DC input power (red wire). The red wire does exit the connector and leads directly to the boiler thermal switch, BUT it also has a hidden fusible link right before the thermal switch. You will see what looks like black electrical tape around the red wire ( this is the fusible link. The fusible link looked good but it was was bad because this is where my power stopped and I had voltage across the link. In a pinch I jumped the link (until I can replace it) and Voila, power restored. Thank you for leading me down the path!
Glad you found it and thanks for the extra info. I did not know there was a fuse there.
Great catch! Fusible links can get overlooked as they just look like a wire splice. I'll keep my eyes open for one as I dig into my unit.
Man, what a good troubleshooting video. Great content.
Glad it helped! Hope you are well. Take care.
Very Great video! Thanks for going through several options. Mine was the hidden fault switch thats behind the galvanized panel. Forgot to turn off the fridge and it faulted out there.
Thanks so much!!!!
Glad it helped!
Seriously saying this is the best video I’ve seen, very detailed Thks I’ve learned a lot
Glad it was useful. Thanks for watching.
Amazing video!! An easy how to troubleshoot!! I’m no dummy but I’m not electrician either. This video is perfect for people like me and it helped me solve my issue!! Awesome, thanks a lot!!!
Glad it was helpful! Thanks.
Great video, I didn't know there was a reset on the thermistor, we got hit with a cold snap -50 Celsius with wind-chill. The fridge froze up, everything else checked out fine, was pulling my hair out. She started right back up, once I reset the thermistor.
Thank you big time
Glad it helped.
Oh, this is keeper vid! Understand it! Love it! I have a 2021 Dometic RM2454 rv refrigerator running on ac intermittently the lights on on upper control panel start cycling on where ultimately all the lights are on! Have “debugging” this for months! The frig seems to operate normally - but, I can’t catch and analyze system during apparent random cycling. Dometic not helpful. Almost read to replace both upper and lowered control panels.
Let me know what you find. Good luck.
Thank you for your trouble shooting video.
Very helpful.
The switch that was tripped is called a limit switch. It trips if the temperature rises above it's set point.
Glad it was helpful! Thank you.
Excellent overview….I’m removing my 2013 Winnebago Lite Five 5th Wheel from storage and this exact situ exists. I’ll TS and revert with findings. Thx again.
Let me know how it goes. I hope it's minor.
Thanks for the video. I’m new to RV-ing. We were out camping and my gas pressure regulator went bad which must have tripped the sensor at 11:33. After I changed the regulator the fridge still didn’t work but everything’s ship-shape now. 👊🏼
Glad it helped
Very well done, & great video ! Clear, & exact, & your speech is just perfect...We have a RETS 33, & that RV has TWO of these fridges side by side....As of now, we have one works great,
( as they normally do) & one, has gone KAPUT ! So I tuned into your video, & such great detail, I will get out & get after it, to get #2 fridge running again...Thankyou so much !
Glad it was helpful! Hope you get it going!
@@SeidelRanch Yes Sir! Thankyou...
Great video.
I can't get mine to work.
I will be watching this again.
Once it warms up a little.
Mine has the blinking light inside so I will be checking what I learned from you.
Thank you 😊
Hope it helps fix your issue. Good luck.
Did you figure out your issue? We have a blinking light on the DMC4101 (electric only) and are about to start pulling things apart.
@@dawnmarrs9412 I bought and installed a new dinosaur motherboard. Now I don't have a blinking light. It works when I wire it up directly or if I hot wire the ignitor. But automatically it still doesn't work. And I haven't had time to look at it anymore 🙃 lately 😕
Thank you for your video. My brother's trailer fridge went out and by following the instructions I was able to get it to reset
Glad it helped
Thank you for making a wonderful, detailed, and easy to follow video. That little thermal button was my issue.
Glad it helped!
Very informative video. Saved the day. Our problem was one of the thermofuses.
Great to hear! Glad it was minor.
dude!!! you are the bomb!!! that was everything i needed to figure out!!! ty so much!! now i have half a chance figuring out whats wrong w my fridge!!!
Awesome. Glad it was helpful. Good luck.
@@SeidelRanchI have a prowler camper. My refrigerator panel lights up but will not cool (it defrosted itself because the freezer was full of ice). No yellow fluid coming out of the back . Any thoughts on my problem
@@GaHullbillyRanch It could be a number of things. Check fuses and power to the back. Make sure all the needed voltage is getting to where it needs to be. That is what I would check first.
The round item with the popped out button is called a Thermodisk. It is a safety device and will interrupt operation if it is over heated. It can be tested for 12v DC on both sides also. The 5/6 wire harness can be tested plugged in with fine probes. You can place the negative off the mm into the red wire and the positive to the orange, that is power up to the control panel aka the eye brow. Keep on red, the green in the upper right corner is gas down and to black is electric down.
Thanks for the extra info.
Best job I have seen, great work !
Thank you! I hope it helped you find the issue.
Wonderful! Helped me fix my refrigerator!!!
That's great. Glad it helped.
Thank you my rv had the exact same problem yours did. Subscribed!
Sorry to hear you had the same issue. Hope the video helped. Thanks for subscribing!
Thank you!!! This is really good! Do you have any videos on diagnosing RV/Trailer drive lights are not working when plugged into vehicle. Break and turn signal lights, as well as trailer breaks work, just drive lights are not illuminating.
I don't, but I would start by narrowing it down by testing the truck outlet and making sure all that is good. If the tow vehicle is sending voltage, then I would test the wires in the trailer connector. Those 7 way connectors sometimes come loose inside and you have to pull the cap off and tighten it. Hope that helps.
My issue wound up being a 1.5 volt resistor in the line going from power over to the reset button on the gas tube, where the rest switch is. I ordered a new one on the radioshack website, crimped it and it worked perfectly!
Nice to know. One more thing to test if the issue arises. Thanks.
man I gotta say see was the best video you explained it from start to finish .very good video an very helpful 👍
I appreciate that! Thanks.
My fridge has power but has never got cold or even cool. I've had it since January and the camper is a 2018. I'm stationery so I dont need the propane option. Loved this video and I'm going to subscribe and check out your other videos.
Thanks. Yeah, we ended up doing this: ruclips.net/video/mxYPcA0Mvu4/видео.html
Thank You! My Dometic fridge stopped working. I followed the instructions in the video, and after I pressed the button on the sensor it started up again!
Glad it helped
This video saved our day on the lake. We found a thermo fuse that was bad in the 12V power line thanks to your video helping us know where to start. Thank you!
Glad it helped. Hope your day on the lake was great.
I had same issue, didn’t even know that thermo fuse was there. Had 12 vdc where wires went in, but not at stove pipe. Pulled insulation & found it, just twisted wires together for quick fix & refrigerator turned on.
@@bladefrk34 Glad it was a simple fix.
Thank you very much for the great video. It really helped me tremendously.
great video it helped me resolve my issue. THANK YOU !
Glad it helped. Thanks for watching and liking the video!
Thank you so much!! My fridge wasn’t working for like a week and my food was going bad. This helped me a lot! Mine was tripped at the dc connection the little black button. Ugh thank god! Lol
Glad it was helpful. Thanks.
Thank you so much.. I can now go troubleshoot mine. Comprehensive information!
You're welcome! Hope you find the issue and it's simple.
The switch you pressed in is a Thermal switch it will kill the power if the burner tube is to hot to prevent a fire. Because your ammonia leaked out it was unable to pull the heat away from the burner tube and tripped your thermal switch. Over all very nice video
Thank you for the extra info. All of it helps.
I went through all these tests and all the power is there to everything. Light is on inside the fridge and it sounds like it runs for a while and shuts off. Still no cooling in fridge or freezer.. Zero signs of am onia leaking. Plugged in at home plus propane is on along with good batteries.
@@rockycon1967
I'm having the same issues. Any luck figuring out the problem? N.FL
This video is immensely valuable, thank you!
Glad it was helpful.
I lucked out. Mine was that silly "button". I was using an ice chest for 2 weeks waiting to fix this thing haha. Thanks man!!
Glad I could help! Keep an eye on it. If it keeps doing that look deeper for leaks. Good luck.
Best video I've seen for this. Sub and figured out a fuse was out on the board
Awesome. Glad it was just a fuse. Thanks for the comment.
Thanks for the help!
No problem!
Very well done and helpful- thank you !!!
Glad it was helpful!
Currently camping in 110 degree weather with my pregnant wife and our fridge quit working your video saved my ass and made me look like a hero thanks so much for the info mine was also the button thing that doesn’t look like a button
So glad it helped you. Hope it's not a deeper issue.
Thank you for this video. We had no idea how to fix it.
Looks like our fridge has the same issue as yours.
Sorry to hear that your fridge went out, but glad I could help with the issue.
I just fixed a 10-year-old and it was the control board. I ordered it and the board on the refrigerator face being it was just $160 both boards together, on Amazon. I also have real ice cubes now. I slid the temp bar on a fin up to the top and its really cold now. Overnight ice. I also keep a frozen 2 litre bottle in there, which helps. Thank you. You talk like I do and think. The new Dometic refrigerator was $1386 at Camper World. Not installed.
Glad it was helpful. Thanks. And yes, these are crazy expensive.
Great job. Thank you for making this video it was a big help. 👍👍❤️
Glad it was helpful!
Terrific video I learn a lot and saved money from paying a Rv guy come out plus I find out sometimes theses wire connections might be a little corrosion or rust on it I pulled them off sanded a little and jingle bells problem solved, I thought my box on outside was gone but found out wires were just dirty or no good contact
That's great. Avoided a very costly repair. My experience with the RV shops is they would have probably just made you pay for a new refrigerator. Glad that was avoided.
@@SeidelRanch keep up the great work again great video step by step, make more thru out Rv hey if you’re going to own one , might as well gain more knowledge
@@Paul-iu1om Thanks. I have some trips in the RV coming up. I will see what I can find to hopefully help the RV community. Thanks for the feedback.
@@SeidelRanch no problem
I got same frigerator, got 120 and to circuit board , but no 12 volt coming in, converter has 120 it’s putting out 13.42 still no 12 volt at refrigerator I’m stump oh I forgot it’s got a dead battery; do we need a working battery lol
Good diagnostic info. Thx !
Thanks. I hope it helped.
Awesome work, thanks for the info. Helped me out alot👍
Glad it helped! Thanks.
Thank you for all the great tips..
Glad you like them! Hope it helped.
Merci pour les bonnes instructions, your explanation ara very good
Thank you.
Hello, excellent, very detailed video from you, thank you. Now a question about this...what would be the problem in the refrigerator if it is connected to propane gas and electricity, the light is on, the automatic light is on but it does not cool. I appreciate your answer.
Is the boiler in the back of the fridge getting hot?
Thank you! Great video! Thanks to you, I found the issue! Thanks again for the great information, much appreciated
Glad it helped!
Incredible video!!!! Thanks for share!!! 👍👍👍👍
Glad it was helpful! Thank you.
Great video, answered a lot of questions.
Glad it was helpful!
Such a helpful video. Thank you!!
Glad it helped.
Your video really help me understand what's wrong my fridge thank you
Glad I could help.
I do need some help please, I have just replace both boards and the fridge still isn't working. I used a multi meter to check all the power after installing the new boards, but still no power. My fridge doesn't have a leak like yours. Any suggestions? Greatly appreciated
The switch fixed it for me you are the man
Glad you got it working.
Very helpful, thank you!
Glad it was helpful!
Super good video my friend excellent troubleshooting skills thank you very much
Glad it helped
thanks for this! helped me troubleshoot my issue
Awesome. Thanks for watching.
Thanks for the video and info!
Glad it was helpful. Thanks.
Well done troubleshooting video.
Thanks. Glad it was helpful.
Very nice job of teaching trouble shooting the system one question so if you heater tank is leaking on the system can that be replaced or is the unit junk ?
It can be replaced, but you have to pull the whole unit out and take the cooling system off to put a new one on. I personally never liked the refrigerator anyway so I did this: ruclips.net/video/mxYPcA0Mvu4/видео.html
Nice! clear and detail
Glad you think so!
Such a good video thank you so much!!
Glad you liked it! Hope it helped.
Thank you very much sir. Very clear explanations. Very very helpful
Thank you. Glad it was helpful.
Great video! When we got to the 12 V DC end our meter read 8.71. Now what should we do?
Sounds like either a weak 12 volt battery or the wiring for the 12 volt connection is too weak. I bet it's the battery though.
Excellent thanks!! Sad thing is, still no luck on our fridge
Sorry to hear that. We do love our new fridge if that helps any.
@@SeidelRanch I'm just buying a cheap household fridge and a inverter
Aww, have another go at , didn't have a probe in all the way
Excellent. So helpful.
Glad it was helpful!
This is an outstanding video, thank you thank you thank you!!
Glad it was helpful!
this helped me out a lot, TY very much
Glad it helped. Thank you.
Great video kudos to you just what I needed to know
Awesome. Glad I could help. Thanks.
Hey!! We just got our new trailer and in our first rv park, after plugging in the electrical and all we realized the ac was working, the microwave was as well but the fridge light wasn’t even on. I pressed it and as expected nothing happened. We never used this Narcold Eletric fridge before… do you have any idea what this could be or what we should do?
Thank you so much!
Have you checked all the breakers and plugs? Sometimes if it's new they may have the breaker turned off.
Lot of good info, thanks a lot!
Glad you enjoyed it! Hope it was helpful.
@@SeidelRanch I told my wife it’s your fault I had to purchase a voltage meter 🤣🤣
@@kevenorr6592 That is the best way to buy it. I use that excuse all the time.
Just wanted to say thank you, same problem.
Sorry to hear yours has a cooling leak. Hope it's under warranty.
The best video ever thank you so very much
You're welcome. Glad you liked it.
The little button "sensor" is usually a bimetal thermostate, used as an over temp safety switch. You will find them again on the hotwater heater
That is good info to have, thank you.
Yeah on the schematic, it’s called a thermofuse.
Great job only thing left was to show troubleshooting thermoster in fridge, it think the black button is an overtemp protection on the bimetal switch on the exhaust
Thank you. Yeah, forgot about going over that at the time.
Great walk through, now going to see what I find wrong with mine. Cheers friend
Glad to help. Hope you found the issue and it was simple.
Thanks for the video! Mine wasn't any of that, but the 12 volt wire going to that little button has a resistor soldered with a heat shield. Still very helpful 👍 -CXD
Glad it helped
excellent video best one ive seen on youtube.
Wow, thanks! Glad it was helpful.
Thanks for the Vid, Our fridge and lights turn on but then that breaker trips and shuts everything off. we just replaced the main control board in the back of fridge but this problem still persists. no leaks seem to be happening. thoughts?
If it's popping a breaker, than the 120v power is shorting somewhere. Can you run it on propane ok? If so, it might be a 120v heating element.
Awesome video, thanks
Glad you liked it!
Thank you. I have the same problem with the small black button.
Hope it helped. Thanks for watching.
So our camper is at a seasonal campground. The fridge worked fine on 110 but we wanted a bigger fridge so I pulled the dometic out
Same fridge as jn this video.
We have not had a battery in our camper for 3 years as we run power off 110
4 days since I pulled it out of camper and the fridge does not work when I plug it in my garage?
No lights ON on front panel.
Would the battery wires have anything to do with this?
Great info, thanks.
Glad it was helpful!
What are those white connectors called that hook up to the thermocoupler?
Great video. Thank you
Glad you liked it!
Great help 😊 thanks
Glad it helped.
Hit the button on the boiler and it turned right on, thanks!!! so does this mean i need to replace that? i did not see any leaking.
It could have just been one of those times and tripped. I would watch it though. If you keep having the issue I would suspect a leak.
