Hello - I’m having trouble with my GE Profile side-by-side refrig. This unit has a single compressor and 2 evaporators (freezer + fridge). There is a defrost heater of the freezer evap, but not the fridge evap. I’m having trouble with the fridge evap totally frosting over to the point where there is no airflow - then fridge temps start to rise. The freezer coils seem to do ok. I’ve confirmed the defrost heater functions - by manually triggering it in the diagnostics. I’ve checked out the thermistor resistances - and they all seem ok (they pass diagnostics too). One troubleshooting diagram sugegsted replacing the main board when you have this situation (when thermisters and heater coil check out OK). I’ve replaced the board, but still seem to be having this heavy frost problem on the refrig side. One thing I’ve noticed is that the refrig evap cover, which is a shaped foam piece with plastic skin, seems to be heavy - like its absorbed moisture - and probably no longer much of an insulator. I’m still wondering how the refrig evap coil is supposed to get adequate defrost. I’m also thinking there must be a solinoid that controls refrigerant delivery to the refrig coil - how likely is that sort of failure?
I’m wondering what I should try next. Ideas?
Thanks,
Jeremy
