Having been extremely frustrated with fixing computerized refrigerators, I have finally found enough information. There are whole websites dedicated to listing the problems with GE computerized refrigerators, model numbers starting with GS and PS (all side-by-sides after 2001). Some of the problems are:
Designing the mother board to intentionally burn out a 2.1 ohm, 1/4 watt resistor if a fan motor goes bad, instead of installing a fuse, a current limiter that responds to heat (forgot what these self resetting devices are called), or using the MCU to detect overcurrent.
Being plagued with a bad batch of thermistors.
Using poor quality fan motors that fail way more often that the old 4 watt, 120 VAC motors, and when they fail and take the motherboard out, the price is about $200 for parts.
Wiring harness failures (open circuit to thermistor).
Overheated compressor relay and associated bad solder joint for the relay on the motherboard.
After seeing GE Factory Service throw 2 of these in the dumpster, and me going crazy for weeks trying to fix them, I can not recommend GE refrigerators.
