Oven overheats, may shut off mid-cycle, display shows F2 or F2 followed by a beep.

Safety first: Turn off power at the breaker. Do not use the oven until the cause of overheating is identified.

• Check the temperature sensor: Access the sensor at the rear of the cavity. Remove and test resistance at room temperature. If resistance is much lower than specified (indicating a short), replace the sensor.
• Inspect wiring for shorts: Follow the sensor harness from the cavity to the control board. Look for melted insulation or points where the wire may touch the metal chassis. Repair or replace damaged wiring.
• Verify cooling fan operation: Restore power briefly and start a low-temperature bake. Confirm that the internal cooling fan behind the control panel starts running after a few minutes. If the fan does not run, check the fan motor and its wiring. Replace the cooling fan motor if seized or open.
• Check for stuck relay: If the oven continues heating even after being turned off, the bake or broil relay on the main control board may be welded closed. In this case, the control board must be replaced.
• After repairs: Reset power, clear the error, and test at a moderate temperature while monitoring for normal cycling and no further F2 codes.
