Thanks in advance for any help on fixing this. I have a maytag french door fridge where the freezer is fine but the coils in the back are freezing up solid causing the fridge to stop getting cold air. Fan is good and I just replaced the control board and the heater has not come on. The heater was checked for continuity and seems good (I think it was .30 and the thermostat was reading (.2) overnight when it was cold. what else can be the problem? anyone?
If heater is good and you replaced the control all you have left is the defrost thermostat.
