Hi - hope everybody likes a challenge! I have a used GE Monogram that I bought with all it's issues and the compressor runs a lot it seems, and the fresh food side is continually too cold.

If I set it for 0-FZ and 37-FF it will be 0/27 after 12 hours. If I set it for 0/46 it will still be 0/27.

Here's what I've done: I've run the onboard diagnostics and all check out for damper action, thermistor continuity, etc.

I checked the thermistors with a meter and the expected resistance throughout the range of temps is achieved on all 4 thermistors. FZ, FF1, FF2, EVAP They are all the flat top style with white sealant.

The dampers have all been visually inspected and all three work. (Fridge top, 2 in climate controlled drawer at bottom)

I've verified temps with thermometer.

I've replaced control board.

SO I'm wondering why the compressor runs excessively even when below set temp, and I'm wondering how it's possible for FF side to continue to cool with all dampers closed!

THIS THING! Arrrghh
