GE Profile Bottom Freezer Cool, Top Refrigerator NOT!

"Josh Brasel- I really doubt it is the evap fan. You would get an error code and you would not have the condensation. It goes into a defrost 3-5 times a day, depending on your unit. That last for 20-30 min. You can hear a sizzle when the water hits the heater. Have you noticed that? You could be timing it just right and witnessing the unit in defrost. There is a defrost sensor and a temperature sensor that could be failing. Although, they usually work or don't work. The main control board controls how long it is defrost. As far as testing each component, that is difficult. Its done at the control board. Its complicated, temperature and ambient temperature need to be considered for each test. I would suggest keeping a log of the time of day, the temp of both freezer and fresh food sections, what noises you hear, any error codes, and don't unplug it or reset it. Let it do what it is doing. It might just be in defrost. Keep track of how long it stays in this mode.

This unit has a duel evaporator it has a 3 way valve on the compressor possible. This controls the flow of gas from one evap to the other. It is part of the sealed system and only a qualified HVAC EPA certified technician can do the repairs. You might call GE to find out how long your sealed system is covered. I hope this helps in some way. Good luck"

Per your symptom there Is a high chance the fan I ls collapsed in ice and won't rotate . This is not going to give and error code because it's intermittent and mechanical rather Than signal error. The problem is the drain tubes are closed off with foreign debris. To repair the issue unplug the unit overnight this will serve as force defrost . The next remove the cover plate on the back of refrigerator ,now pull the drain tubes ,water should come out the drain holes, make sure to remove the foreign substance wash the tubes place them back , vacuum around the condenser are and . Plug in the refrigerator. The issue should be resolved.
