This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Open or shorted freezer thermistor, Damaged wiring harness, Faulty main control board input

Safety first: Unplug the refrigerator before accessing the freezer rear panel.

Steps:

Inspect freezer thermistor: As in E2, locate the sensor on or near the evaporator. Check for physical damage or disconnection.
Test and replace: Measure resistance and compare to expected values. Replace with a Magic Chef-compatible thermistor if readings are abnormal.
Check wiring: Inspect and test continuity of the harness back to the control board.
Control board: If sensor and wiring are good, the main control board may need replacement.
