- RE-upload since not everyone likes my jokes. Rheem thermistors are not difficult to test and change, this video will show a process to test and repolace the main 3 up top at the heat pump unit.
Very helpful and informative. Thanks! Too much extraneous banter for me. I want to understand and get the job done. Other than that, yours is the best video out there on DIY Rheem repair!👊👍
@@UberROCK1 I appreciate you leaving a comment. Thank you :)
Been looking high and low for a simple explanation of what each thermistor is supposed to tell me. Finally... Informational from start to finish, also a big fan of not guessing but testing. I appreciate banter and subtle jokes - sorry you had to edit. Anyway. Rheem tech support gave me the part and told me what to do, but I needed to know why I was doing it, what the issue was, why the sensor I was asked to replace wasn't mentioned in the error code I was getting. Information out there is vague and often f'in meaningless/waste of time. Yes its a long video, but take the time and learn why your doing what your doing. Damn, thanks so much for taking the time to make this.
@@EricZettlemoyer-s1y thank you. If I can find a way to combine my humor and my love for water heaters one day I’ll be happy. Appreciate you leaving a comment
Thank you for your video. I was able to replace my thermistor using your video.
Might be worth mentioning, Rheem doesn't send out a bunch of thermistors anymore, or atleast not this time. The tech on the phone walked me through all the diagnostic menu steps and had me pull a reading for all the thermistors. They determined that it was the evap thermistor, which with the info in your video, I was able to understand why they thought that, and confirm it for myself. They sent out Rheem part# SP20845, a thermistor kit. It contained one thermistor, 3 different size clips, and a piece of sticky "cork" tape. Maybe they heard you in regards to testing and not mailing people multiple thermistors. The kit appears to retail for 2-3 times that of just one thermistor - so cost efficiency still isn't a priority.
It would have been an excellent video if you cut out the waffling and focussed on the topic. I wanted the learn something but you kept waffling!
Great Video! My unit looked a little different and to access the EV thermistor I had to lift up the upper cover (the 18" section that covers up all the heat pump stuff). Just 4 screws and I could get at it from the side. Thanks!
Your guide to replace these was given to me by support, but i find this video would have been informative too
When replacing thermistors do you suggest using "anti- oxidant joint compound" ??
Video is way to long!
Been getting some error codes lately. A005 Discharge temp high overnight 2 days ago and then A108 Condensate Blocked: Unclog Line overnight last night. I keep the unit in heat pump only mode and it appears to be working fine so not sure if maybe a thermistor is going bad. Going to wait and see what happens as I have this unit in series with a dumb Rheem unit as storage/backup so not a big deal if it fails.
I am saving about $400 a year with this unit in heat pump only mode. It uses more energy in Energy Saver mode, ironically.
Really hoping this thing fails at 9 years and 9 months as it will pay for itself in about 3.5 years with my DIY install cost of $1500 on a 50 gallon unit.
That will be about $6000+ in net savings over 20 years by installing this unit in Georgia. Yes it makes an annoying wining noise so install it in a garage and yes it works when it is 20 degrees outside. Runs a lot in the winter and a lot less in the hot summer when the garage is 90 degrees.
I installed the second unit as a smart Rheem unit failed 2x and they acted like it was no big deal to wait 3-4 days for a part each time. Now I will never run out of hot water and it will never be an emergency to replace or fix one of the units.
Install these with flex connectors so you can easily swap one out if Rheem gives you a return number to take it back to the store.
Great video, thanks!
Called Rheem and they ran through the diagnostic test. Determined the Evap Thermistor is bad and are shipping a new thermistor, clip and cork tape out Fedex.
Alarm just went off and I noticed that the unit overrides my choice of Heat Pump only mode and turns on the elements when the compressor turns off due to an alarm. Good to know for anyone that might try to use this in heat pump only mode off-grid and keep amperage low.
Will test the bad thermistor and report on the results.
Thermistor was bad. Was reading 4.5 kohm at 73 degrees on a 10k ohm NTC. ET in diagnostic reading 60 degrees at 85 ambient or 25 degree delta. No alarms for a few days now.
