GE profile Refrigerator Model # PFS2251SBSS

Usally if its the motherboard it will have a burnt mark on it.. I just replaced the run capacitor and my compressor started working again. I would try this first for 13.00 before buying a board or other items unless like I said you look at your board and see a black mark

You must be referring to the compressor. It's possible it could be your main control board on the back of the unit. Typically its these main boards that go out, as they control everything on your GE Refrig, pretty much. If its not the board, it could be your Relay on the compressor, or the compressor its self, however, in my experience, GE's compressors are pretty decent.
