I have a 15+ year old GE Monogram 42" side by side built in refrigerator model zisw42emb that over the last few weeks is showing Error FF on the freezer door information panel. Usually it goes away in several hours or if I power off/on the refrigerator. I vacuumed the dust from the condenser and surrounding parts. The freezer is still cold enough. Also, the Warm Temperature light comes on for a bit but not as long as Error FF.
It appears the condenser fan runs more often than in the past.
Now I’m getting a CC error in additional to the FF error. The refrigerator is cold but the freezer is warmer. I have the temperature dial in the freezer set to 9. If I unplug the power for a few minutes the error messages go away for a while but return shortly.
If both evaporator and condenser motors are running and the condenser is clean I recommend you to call the service co. It may be a sealed system problem.
Also, i want to take the panel off in the freezer to check the coils for frost. Is their a service manual to help me understand the best way to do this?
