Defrost on GE GSH25JSTA SS

[gangemcs]

Hi.  I recently changed out the Motherboard on my side by side GE refrigerator/freezer as the evap was frozen over.  At same time I changed the thermister.  I had determined the defroster and the defrost thermostat were good.  All has been good except now I see the temp is fluctuating a bit.  Just tonight the freezer temp was going above 40 degrees. I could hear the condenser fan running as well as the compressor so I was thinking the evap fan was bad.  Then all of a sudden I see the evap fan is running.  Is it possible I caught it during a defrost cycle.  What will temp of the box go up to?  Is it common that the compressor would run during this cycle?

Thanks,

Did you change both thermistors in the freezer?
