Dear Experts,

Yes, its yet another GE refrigerator with the freezer evaporator coils frosted solid. Model GSS25LGPACC is the model. To date I have replaced the defrost heater (it did check ok at 21.7 ohms but was very black so replaced it) and the defrost thermostat. Did not fix the problem.

Is my next step to test/replace the motherboard? Or should I perhaps replace one or both thermisters in the freezer compartment first and see if that solves the problem? One thermister is hard wired to the evaporator fan motor and taped to the top of the evap. coil and the other is in the right side freezer wall behind a grille. Evaporator fan seems to run fine. Obviously I don't want to just throw parts at it and hope...

If you recommend testing/replacing the motherboard, and I know this is redundant, could you explain EXACTLY which 2 pins I need to put a jumper wire on and what my digital multimeter should read if board is good and what it would read if bad. If you could include a photo of the board off the APP parts diagram with pin location circled that would be GREAT but not necessary if its a hassle. Want to be CERTAIN it is bad before I buy that expensive part.

Finally, I recall I read somewhere that if you have to replace the motherboard you should also replace the evaporator fan motor (which seems fine) and all thermisters (which appear visually ok) at the same time...Is all or part of that statement correct?

Am I missing anything or on the wrong track? Could it be anything else?

Thank you VERY MUCH for your help..

Hi utzig,

yeah I think there are a lot of us out there having problems with these GE's--I know how ya feel. Did you know there was a recall on the motherboards a while back? I didn't until this problem surfaced--not sure if we are covered by it or not.

Anyway, whats holding me back on just purchasing the motherboard and installing it is the same reason as you--once installed you own it--even if that doesn't fix the problem. I'm hoping one of the forum experts will chime in with some help on testing motherboards.

Say, what site did you find the part for $127? I called our local supply outlet, they quoted me $148--I think I'll ask about a price match too, good tip. By the way, the guy told me they have 515 boards on hand right now but says he cant keep them in stock during the summer--says they go out all the time--kinda telling isn't it...

I talked with GE a couple days ago, and they did not mention a recall to me.

I did see something on that but it was from years ago and I think the time is up for it.

I just bought a house and this fridge was here. It had sat dormant for a year. It worked for a couple days and then went down hill.

I will never buy another GE appliance after what O have learned the past few days.!!!

New motherboard did fix the problem.

You can check them at the control board by unplugging and testing there.

However, I actually just cut the wires, took the thermisters off and put them in ice water. I then tested the resistance at approx. 32 degrees F. You want a resistance of around 16.7 ohms or so at 32 degrees.

Then I just spliced them back together.
