whirlpool Gold fresh food section coils frozen

Hello There is not a heater for the FF section evaporator. The refrigerator maintains 38-44 degrees. When the control board cycles off at 3-44 degrees , the evaporator defrosts manually on temperatures alone. No need for a heater if coil temperature is above 32 degrees.

Did you run it through diagnostics ? Is there any error codes ? If no error codes I would replace board and Fresh Food thermistor
