2 1/2 months ago my refrigerator was warm and freezer was fine.
Replaced the defrost timer and all seemed fine for about 1 month, then the same thing happened. This time replaced the thermostat and watched it for a few days. Everything seemed good, it was defrosting properly. Put it back together and started using it again. Today, a month and a half later, the same darn thing is going on.
All I know that’s let is the heater. Can the heater be bad if it is defrosting when I put the freezer in defrost mode?
Any and all help is greatly appreciated,
Tom
Also check the heater mounting.
Check the wiring especially where it bends around the frame, could be a wire has lost it’s insulation.
A bad ground can also be in the wall receptacle.
