GE PSC25SGSC randomly getting warm on both sides
(Fair Oaks, CA)
I have read your writings on the GE Profile repair steps and I'd like some clarification if possible. My unit is the PSC25SGSC and it is randomly warming up the freezer and the refrigerator sides to 20/47 or so. I can unplug the unit for 5 minutes and power back on and it will typically be fine for a month or so. Recently the problem has come about once a week. My suspicions are the main board but are there any concerns that if it is a fan or thermistor causing the problem that a new board will get blown out as well?Answer

The thermistors will not cause the board to fail.
If the fan is shorted it will blow a resistor on the board but unplugging the refrigerator then plugging it back in would not make it go back to work if this were the case.
I believe your problem is going to be the main board however your model is a dual evaporator model, which makes things more complicated. I been wanting to write repair pages on these models but I really need more real world experience on them before I do so. I have been to service schools and have service manual but don’t want to write about them until I have real experience on them.
You have a three-way valve and a compressor inverter that could also be your problem. Turing off the power to the refrigerator will reset the three-way valve but since it goes back to work we know the valve is at least moving. The valve has three positions and when you unplug the refrigerator and reconnect it the valve will return to home position. Since it is turning we can assume it is working.
The inverter is what provides power to the compressor but will only do what the main board “tells” it to do.
The problem can be in the inverter board or the main board but there isn’t a real good way to tell for sure which one. If you catch it in the act (when it is not cooling) you can tell if the main board is calling for the compressor to be running but the compressor is so quiet and runs so cool you can tell if the compressor is running or not. If the refrigerator is not cooling and the main board is not calling for the compressor to run then the main board is bad. If the main is calling for the compressor to run and it is not cooling then we can assume that the compressor is not running and the inverter is bad. It will not be the compressor because when you unplug the refrigerator and plug it back it goes back to work.
If you have a voltage tester you can check for output voltage on the main board. Set the meter to read 4-12 VDC. On the main board you will see two wires marked J15-1 and J15-2. If the main board is calling for the compressor to be running you will read between 4 and 6 VDC between the wires. I hope this helps!!
