This customer has this gigantic refrigerator/freezer. It looks like the Model # is only for the refrigerator section.
The coils iced up last year and she had a company replace the defrost heater and thermostat and the main control in the console near the ceiling.
Now, her complaint is, the refrigerator temperatures are fluctuating all over the place.
She sets the control to 4 and the temp may go up to 40 or 45 degrees.
If she sets it full at 7 the temp goes down sometimes to 20 or 30 degrees.
Seems like a runaway cold control, but I'm not sure what controls the temperature in this refrigerator.
Is it the same main control (part #297334200)? Or is there something in there that acts as a cold control.
Thanks in advance,
