GE Refrigerator Error Code F2

The F2 error code on a GE refrigerator indicates an oven over-temperature condition. This code is triggered when the oven sensor reads a temperature above 650°F while the door latch is in the unlatched position, or above 915°F when the latch is engaged during a self-clean cycle. A third trigger condition occurs when the cooling fan stalls while the oven cavity is above 650°F, causing the thermal switch to open as a protective response. The F2 code is essentially the control board's way of flagging that heat inside the oven has reached a potentially damaging or dangerous level.

The most mechanically significant cause of F2 is welded relay contacts on the oven control board. When relay contacts fuse together, they allow continuous voltage to flow to the bake or broil element even without a command from the control board, causing uncontrolled heating. A stalled or physically blocked cooling fan is another critical factor. The cooling fan prevents heat from migrating into the control cavity and helps regulate temperatures around the thermal switch. If the fan fails or its airflow path is obstructed, the thermal switch opens and triggers F2 even if the actual oven temperature is within normal range.

High resistance in the oven sensor circuit is also a known contributor. Corroded connectors or degraded wiring between the sensor and the control board can cause the board to receive a falsely elevated resistance reading, which it interprets as an extreme temperature. Restricted airflow to the rear of the unit compounds thermal management problems. Diagnosing F2 requires systematically checking relay contacts, fan operation, rear clearance, and sensor lead integrity before replacing components.
