How to Fix 4C Error

UNPLUG THE REFRIGERATOR. This error indicates a failure of the freezer compartment’s defrost sensor.
Empty the freezer and remove all drawers and the rear interior panel to expose the freezer evaporator coils.
The defrost sensor is clipped onto the evaporator coils. Disconnect its wire harness.
Test the sensor’s resistance with a multimeter. An infinite (open) or zero (shorted) reading means it has failed.
Replace the sensor, ensuring it is securely clipped to the coil. Reconnect the wiring and reassemble the freezer interior.
