Freezer has wild swings in temp
I have a GE Profile french door (model no. PFSF5NFYA BB). For about a week now I have had an issue where the freezer goes up to about 40F degrees then back down to 0. This process takes about 6 hours. So it is not a normal defrost cycle. But it does seem like it may be correlated. After doing research I replaced the freezer defrost thermostat and the thermistor. This looked like it may have fixed the issue, but after about 24 hours of it not happening, it started again.
The freezer does eventually get down to 0 again, but it takes so long that the ice will almost totally melt then completely refreeze. Any help would be appreciated. Thanks

Wanted to follow up. I replaced the inverter and that did it. Been a few weeks and still running properly
Esta é uma boa pergunta?

Hi @ephraimschmitt,
In the 6 hours is the compressor running continually trying to drive the temp back down to the set operating temp?
Can you hear if the evaporator fan is running when the compressor is running? Usually opening a door (either door) will stop the fan, but the compressor will keep on going. Closing the door will start it again

The freezer is currently at 40 and the fridge at 42. I opened the door to the freezer and the fan is running (open or closed doesn't seem to matter). I cannot tell if the compressor is running. It does not appear to be running though from what I can tell ( a little hard as I don't know if what I am hearing is a compressor or just the loud fan, but appears to be the fan)

If you can access the compressor you should be able to "feel" it operating (careful it may be hot but it really shouldn't be, warm yes too hot to touch no) although if the condenser fan is also running it is because the refrigerant needs to be cooled which might indicate that it is being pumped through the sealed system.
Do the lights in each compartment go out when you manually operate the door switch with the door open?
Unusual for the evap fan to run with a door open as you don't want cold air being blown out of the either compartment. It is the door switch that signals the control board to turn off the evap fan and also turn on the light(s). The condenser fan if operating will continue to run regardless of the doors being open or shut.

Ok, so the compressor was cold to the touch. The condenser fan was running. And this time when I opened the freezer The evaporator fan was off, but flipping the switch made it sound like the compressor was kicking on and off (sound of pressure releasing each time then something other then the evaporator fan running). Then after a few minutes the evaporator fan kicked in. The evaporator fan does not seem to flip with the open/close switch. But I feel like that is normal for this fridge. It is at 44 degrees now, so I will wait a bit and see if it goes down (now that it sounds like the compressor might be running?)

Just checked an after a hour it is down to 39 degrees and it sounds like the compressor is still running.
