GE Oven F2: Over-Temperature Cutoff — Cavity Exceeded Safe Maximum

F2 is a safety shutdown. The oven temperature sensor detected temperatures above 615-650F during normal baking or above 915F during self-clean. The ERC immediately kills all heating elements.

Safety Urgency

F2 means genuine overheating occurred. Possible dangerous causes include a welded relay (element stays energized regardless of commands), a ground-fault element passing current through the chassis, or a drifted sensor causing the board to overheat the cavity.

Immediate Response

1. Turn off the breaker now
2. Open the oven door cautiously if not in self-clean lock
3. Let everything cool completely
4. Do not use the oven until the root cause is identified

Welded Relay Diagnosis

Set oven to 350F. Watch the heating elements. At temperature, elements should cycle off (stop glowing). If an element stays continuously orange past the set temperature, its relay contact is welded shut on the ERC board — a fire hazard. Replace the ERC.

Sensor Verification

A sensor reading artificially low makes the board think the oven is cooler than actual. It keeps heating past the real temperature. Test sensor resistance: 1,080-1,100 ohms at room temperature (77F). Significantly below this range indicates drift.

Element Ground Fault Check

Measure insulation resistance between each element terminal and the oven chassis. Should read infinity (OL on multimeter). Any measurable resistance means current is leaking through an unintended path — replace that element.

Parts and Pricing

Professional repair: $200-$500. Diagnosis requires relay testing and sensor verification — methodical process at 45-75 minutes.

Do Not Ignore Recurring F2

A single F2 during self-clean may be within limits. But F2 during normal baking indicates an active malfunction that can cause oven fires.
