When to replace this part

Heat control (thermostats, fuses, heating element)

Symptom: The refrigerator's temperature reads inconsistently, or the compressor and defrost cycle seem out of step with how warm or cold it actually is inside.

Check: A thermistor that has drifted or failed reports the wrong temperature to the control board, so compare the compartment's actual temperature to what the display or dial shows.
