Rheem RGDA model troubleshoot part 1

- Опубликовано: 19 янв 2025
- This is the beginning of the troubleshoot for this furnace. I cover electrical problems up to the ignition control.
This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.
After spending hours ended up just resetting the draft switch and the furnace is purring like a (loud) kitten again thank you! A decade after posting, this video is still helping people fix their furnaces!
If the draft hood switch continues to open, you will need to find out why.

This video saved me a lot of time and trouble. My draft switch just needed to be reset. The previous tenants did not even know that this furnace is still completely operational. Thanks!!
thank you Gary,,,,,,we had massive winter storm and our rheem weird ass furnace went out turned out we had two issues one was beat up thermostat second was gas re flux sensor had been moved from factory placement once exhaust had been checked and sensor reset fired right up....we had grand kids just move in and lost our heat not good...thanks so much for the weird rheem years videos which saved us a bunch of money...god bless you Gary for helping the dyi folks on a tight income....
Glad you got it going.

He nailed it with the "Hidden switch" I remembered a service dude showing us that but could not remember where it was located. All the other help videos I watched where about voltages and wire colors but I knew there had to be one about that darn button switch !!!! Thank you!!!!!!!!!!!!
You sir are awesome. Just fixed my RUUD/Rheem unit with you guidance. Found the draft switch had to be reset.
Glad you got it going. I would be checking the draft hood for spillage during operation.

0:58 luckily I watched this video before calling a repair man. The door was loosened during a party. Thanks!
You win!

I'm not sure if that switch tripped or it is failing but it wasn't conducting right; I didn't know it was resettable so I bought a replacement (different brand, trips as 215F, hope that's right..). In any case, replacing it didn't work - but it turned out that it was because I had the ignition control unit unscrewed from ground (as I was debugging). I saw your other video and got it sorted. Thanks.
I'm learning a lot from your vids Sir... Thanks you very much for Putting out these infos… Bless you Sir.

Hopefully this finds you well. I have a similar model and I keep getting my transformer blown out. I have no schematic to this furnace.
If the transformer burns up, you probably have a short to chassis. I did a series of 2 videos about troubleshooting this problem. ruclips.net/video/eBYunyrImf0/видео.html

How do you connect the voltage meter to the furnace? Thanks.
How it is connected is dependent on what you are trying to check and what your symptoms are.
Give me some symptoms, and I may be able to help.

was there a part 2 to this video troubleshooting no heat?
Thanks for letting me know. Some of my older videos have had the links broken by youtube. I have repaired the links. There are 3 videos in this series. You will find the link at the end of each video.

my rheem model Rrgg 05n31jkr will spark,pilot,light main flamr but then shut off after 5 to 10 seconds. i could not find a flame sensor so could it be with the pilot/igniter? if so can i clean it if so how? or do i have to replace? thanx in advance
The probe that the spark comes from is the sensor. It can be cleaned with sandpaper.
GFM
do u have a video showing me how by any chance? also am i cleaning the top part of the probe like the flat part or around it?
I do not have one. Clean both the top and the sides of both probes.
GFM
ok thank you i will do it this weekeend!
Love you man.. fixed it. I had a fan blowing in my crawl space and guess made that draft thing suck air in wrong direction. Let me send you something. Saved me money for sure. Paypal? Thanks again...
I appreciate the thought but I am not taking anything now. Thanks for the support.

Well I want to do something nice back.. my guess even our local guys would be scratching their heads on this older unit. They could have told me just about anything. I can't thank you enough.
I should have watched your part 1 first,, I watched them backwards figuring it was more complicated… :)
good stuff, thank you...
furnace not staying lit
Need more than that. Does the main burner come on for a few seconds?
