Thanks for the easy to follow video! Had a heat pump installed in 2016, iced up the last two years in winter and finally stopped cooling this summer. Purchased the sensor in this video and fixed the cooling. Hoping it fixes the icing in winter. No experience with HVAC and was able to do this in less than 30 minutes. Thanks again!!!
I would of not known this if this wasn’t for your video, thanks for sharing👍
Just had a call for the same issue. No Heat, and outdoor unit frozen block of ice. Switched out coil and ats and defrost board. With all new part numbers from your reference. Thank you very much.
I’ve had the same freezing-up issue for a few months now since heat was called for. I live in northwest Ga. My unit a 2018 4ton. After pulling the meter out I realized the board and both sensors were bad. Thanks again for bringing this to attention, specifying the replacement parts and taking the time to video it sir. After replacing all 3 it’s been working great!

Great info. I just purchased a board yesterday.pkan to replace it today but with that insight I will hold off until I get the right parts." My hat goes off to you"!.
This is the exact issue I'm having with my 2 month old Rheem heat pump. The tech just replaced the faulty defrost board but didn't use the better sensors. Thank you for this video!!
Thank you for the video. Helped me out alot. I've had this Rheem unit 4 years now and it's been nothing but problems. I know one thing a will never get a Rheem again!
Yes! i have had the same issue. Thank you for the information. I now have the separate coil sensor on order instead of the board/sensor kit. I did not know that there has been issues with the sensors. Thanks again! Kerry
Good evening. I had a newer rheem about 6 years old, very similar to this unit. I had a bad defrost board and replaced the board with the sensors. Called back today with defrost not working, I had replaced the board a few days ago. upon arrival found un it iced up. shorted the pins to put into defrost and only stayed in defrost for less than 30 seconds with sensor incased in ice. This video is very helpful and now i know to get the new sensors. Thanks again
Yes so true I had problems with 5 of them my self I did change the sensor that was the problem sensor that comes with the kit it’s no good whatsoever , great video keep them coming great stuff and stay safe out there
We are having the same issue in Virginia. Going to try your solution as I've been racking my brain with this unit.
Having issues in Idaho as well house was built 2017 I burnt out my compressor motor last winter $$$$$ , it was stuck in defrost mode changed the board out two days ago, now it won’t go into defrost mode , I’m a industrial refrigeration operator so your video was very helpful my local hvac company I got the board from just gave me two new sensors so imma try that
Should fix the problem! Glad I could help. I would like to get into some more refrigeration work. Always thought it was really interesting.
Thank You for sharing this information. This will save me a lot of time.
Thanks for video! I am having same problem with new install at my brothers house.
Thanks for the video. My Rheem system is a little over a year old and it sounds like this is likely why it stopped working. Both LED 1 and 2 are solid on (Coil Sensor Failure).
Yep that would be it
Just changed one tonight it works I’m hoping it does not fail thanks for that advise!
Thank you for this very valuable and timely information.
Thank you I having that same problem with a Lennox
Thank you for the information, great help.
Interesting. We haven't been having problems with new Rheem units, but with Carrier and Lennox.
I have 2 of the same units. 1 no problems the other issue after issue after issue board been replaced multiple times under warranty. I’m going to try this and see if this fixes it. Thank you!
wow thanks dealing with the issue right now
Thanks for the heads up
Thanks for sharing.
What is up with these coil thermistors? I have had the ONLY TWO Honeywell DB7110U1000 defrost controls I bought forTRUCK STOCK, have their coil thermistors go bad within a week of installation.
First time I just replaced the thermistor but the second time I also exchanged the control for fear that the control somehow destroyed the thermistor???
Weird, over 30+ yrs of calls, this is the first time I ever ran into bad sensor issues under warranty. Thanks for the RHEEM INFO! I'll keep an eye out!
Yes! We've had the same problem on the 2018 heat pumps (two stage in this case). A slug fried the original board. Replaced the board, but not the sensors (which tested OK using an ohm meter). Fine in cooling mode, but in heating mode, needless defrosts all the time. Very short defrost cycles, too, so hard on the system and turns on the resistance heaters needlessly. I thought that setting the defrost termination at 70 was the error, but no difference regardless of which of the three settings we use.
SO, should we replace the new board AND both sensors or just the two new sensors?
I find that board part number 47-102684-104 has been replaced by 47-102684-204. Is it safe to assume that the 104 to 204 is compatible?
ALSO -- these outdoor unit cases rattle like crazy. Is there some weatherstripping missing that we can add to end the rattle? It seems that the metal case around the coil is what is loose and missing some sort of vibration dampening.
Thank you for your helpful video!
I was working on a 2 stage heat pump from 20 and the error it was throwing was the coil failure. Bypassed the board until I can get a new board and sensor after the weekend but they are still having problems cooling.
I had a problem with the defrost board blowing the 3a control fuse. Could this be a similar problem?
What happens when you have replaced the board and the sensors with the better parts and both LED are still flashing.
Thanks I have the issue.
I have the same Rheem heat pump and my board does not have the OAT sensor wire on the unit. Should I have that sensor?
Same thing in our area.
Same problem here in NC. Im a newer tech but cant help but notice the constant calls for frozen units due to sensor failures. I like to check everything before replacing the parts, but its a habit to replace them “just in case”. (I do warranty mainly)
Come to tunnel hill Georgia please and fix mine please.. I have had it changed 3 time already. Please fix it
Do you have to replace the board if you replace the sensor?
Mines happing now… 90 degrees in the house in Arizona
Nice…👍
Hi, thanks for the video! I was told that the new kit part# 47-102684-204 has the new sensors with the board which replaces the old kit 4710684-104 that had the bad sensors, can any anyone confirm that the new 208 kit is now good, board and sensors?
👍👍
on the board in the condenser the little led lights are solid re dwould you know what code that is ,put new compresserror in but will only hum wont start up old compressrror came complete apart inside thank you for your time
It will say what each fault code is on that board. It's really small so you got to get up close to it.
@@HVACTechTips ok thank you
Had my Rheem instead this past April. Since turning cold in Maryland and having to turn the heat on it's been making a loud trumpet like or whale call sound before the fan comes on. I was told it was the defrost mode. Is this normal or is this part of the board/sensor issue?
Would this bad sensor cause my condenser fan to cycle on and off even while the compressor is running fine? My fan only runs for about five seconds and then shuts off for about minute and then comes back on for five seconds. Then compressor gets hot and shuts everything down. My defrost board is flashing two blinks so thinking this is the problem. Does it for ac and heat pump modes. Thanks
No this would just effect the defrost in heating. Sounds like it may be a bad board, motor, or capacitor? Can't say for sure unless there's more information given.
More reasons to just stick with a basic a/c
I have a RP2060BJVCA 2 months old system, and the service guy said that my 410A levels look good, Pressure looks good, he checked system during the day when it was 40 degrees. Defrosted fine during the daytime but it won't defrost during the colder nights (28 Degrees) and just shuts down without going into defrost mode. So then it wants to start up with frost on coil. Please someone tell me where to start looking for the problem.
Have you checked the ohms on the bad sensor? I have had one Rheem system so far freezing up. The sensor tested fine. I did a force defrost on the board a couple weeks ago. Its been running fine since.
how do you force the defrost??
Aren't these sensors supposed to be mounted in the middle of the coil?
Exact same unit. Exact same issue. My board has the 2 solid lights and eventually locks out. Do you have any insight on how I can purchase these parts? They're not available on Rheem's website and want me to contact a PRO. I was hoping to perform this repair myself.
You will have a really hard time getting it yourself. It will be best to contact a company. The board and sensor will be under warranty so you would only have to pay labor anyways.
I have a 4 month old rheem sensor on bottom inside unit light ran red, called th.e installers, they blamed in on filter, put a new filter less than a month a go.happened again tonight told my son it froze up, told me it was the filter,,so sick of this, I live in Georgia..ready to get a second opinion..So sick of this..My son paid for it, he is in Alanta, I \live in Gainesville.. The compamy is an hour away.I don't know what to do
What have been the problems occuring that result in changing the board. I've had my board and sensor changed recently And the unit seems to be decorating too often and I have excessive amount of water building up to ice under my unit to the point ground is so saturated the unit is starting to lean
It’s going to stay wet underneath the unit as long as it is cold outside and heating
Two inches of ice surrounding the whole unit?
@@HVACTechTips two inches of thick ice and then some surrounding the whole unit? This didn't occur with my former unit that was there for 14 years.
Yea something is wrong. It should be defrosting the ice
@@HVACTechTips surrounding meaning on the ground not the unit itself. I've never seen this wish my old unit. And this unit has both a regular defrost for 2 mins. Then it will also energize..the fan will spin for 1 second and a defrost will take place for 30 seconds before the fan then comes on in heat mode. The HVAC co says this is normal for Ruud ????
What does it mean if just light 2 is blinking
It should say on the actual board
Maybe time to call TV reporters, let the world know,😢😢
Is the part # of the temp sensor labeled on the temp sensor? I think mine is bad but I don't know which one goes for my old heil 10 unit.. any suggestions
Hi there. Thanks for the video. I had a question though. I've been having a defrost issue with my Rheem Heat Pump. Defrost board and sensors were changed but the problem is still there. I've got the 47-102684-204 board. Do you happen to know if my board has the same issue asbthe board you showed in your video? Thanks!
It’s more about which sensor you have. To be safe I would replace the sensor
@@HVACTechTips thank you!
Thanks for the tip. I have a Rheem (2005) that was new - in box - never installed until 2018, and not put into service until 9/2019. It came with an unfinished home I bought here in the Gatlinburg area. In your video, you never mentioned what "the problem" with the defrost board/sensors was. My problem has been, when in heat mode, it goes into defrost too often and runs for too long. Thus, adding very cold air to the house to be re-heated. (more run time = more $$) Last year I replaced the defrost board with professional installation. Protech 47-102684-83 to replace 47-21517-16. Still doing the same thing. Do you think the sensor kit replacement might solve this problem? I have used a total of four (four) different HVAC companies. I seem to be learning more at RUclips University. Thanks if you can help. John A.
