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 evaporator thermistor, Sensor not in contact with coil, Damaged sensor harness, Faulty main control board

Safety: Disconnect power.

Procedure:

Access evaporator: Remove front cover and expose the evaporator coil.
Locate sensor: Find the thermistor clipped to the coil tubing.
Check contact: Ensure the sensor is firmly attached to the coil. Reattach if loose.
Inspect wiring: Look for damage along the harness and at the connector. Repair or replace as needed.
Test and replace: Measure resistance; if out of spec, install a new GE evaporator thermistor.
Control board: If F2 persists with a known-good sensor, replace the main control board.
