I have been working on a GE SBS Refrigerator model GSH25JFXBWW-S/N TR219919
Compressor runs all the time. Freezer temp is good (between 0 and 5 degrees). FF side is a little high at about 46-50.
Everything else works fine.
Also, I downloaded a schematic for this model from this site (pub. no. 31-51716) but it does not match the actual wiring on the main control board (Low Voltage Side) at J1, J2, J3 and J4.
I didn't want to have to remove each sensor to check it since the diagnostic is supposed to do that. I couldn't check them at the control board because the wiring doesn't match.
I originally determined the main control board was bad and replaced it. Everything worked as it should, so I thought I was done. The compressor was cutting on and off as I adjusted to different temp settings. However, after a few hours after I left, it went back to the compressor running all the time again.
I have tried to run the diagnostics. It goes into diag mode but the tech information I have (which lists similar GE models but doesn't list this specific model) doesn't line up with what I am getting so I don't trust it. For example,
when using diag code 0 2, 03, and 04 to do the communication test
it responds with 01, 4, and P respectively.
When using diag code 0 7, it responds with:
01, P2, P3, P4, 25 When I put in a new Dispenser Board it responds with
01, P2, P3, P4, 05
I have tried to find a different tech manual for this specific model on this site in the appropriate section but could not find one. I am looking for someone to point me in the right direction. Thanks
