Hey guys, this is my first post but I've been fighting this problem for awhile. Let me back up a couple of years.
The initial problem with this GE side by side ( GSH25JSTA SS ) was after a power outage (we've had line problems for a couple of years now).
The refrigerator wouldn't come back on after outage. Lights on inside fridge but no compressor, fans, or lights on icemaker controls.
At first, it wouldn't come back on for 15-30 minutes, then it would come back on. This progressed over the last couple of years to a couple of hours, several hours, and last month, it wouldn't power back up until it was left unplugged for 12-14 hours. This was obviously a problem. I ordered a replacement board (WR55X10942P) to replace the original WR55X23210. I installed it and all was well (for a few weeks) until we had storms in area Monday of this week. Again, just like before with old board, only 120V lights on inside fridge, and would not run.
I verified there was no VDC coming from the circuit board to power fans and front ice/temp control. Unplugged unit several times but didnt power back up. Ended up putting old board back in and it fired right up...
Sorry for the long story but it has me puzzled why the new board is acting the same as old board after an outage
. I havent had time to try the new motherboard again, but if i had to bet money, I bet it would work again now after a few days. There is nothing obviously wrong on wire traces or components of either board. Old board has had some heat around a couple of components in 12 years of service, but nothing obviously wrong.
Im also having an (i think) unrelated issue with freezer temp fluctuations and refrig running too cold that I think is being caused by an out of range thermistor in FF section, the damper will open and close fine in test mode, but seems to be staying open. Thermistors in freezer (2) are in range, but I dont have a spare for FF sec right now. This is unrelated I think, and Im not too concerned about it, but did want to post all issues.
If someone can shed some "light" on what component causes loss of 13VDC power on board after power glitch, and what resets to allow it to come back after X amount of time?!! Thanks.
