Oven overheats, display shows F2, sometimes accompanied by a continuous beep and very high oven temperature.

Safety first: Turn the oven off and switch off the circuit breaker immediately if the oven is overheating. Allow the appliance to cool completely before inspection.

• Visual check: Confirm that the oven is not still heating with controls off. If elements remain red-hot with controls off, leave power off and do not use until repaired.
• Inspect oven temperature sensor: With power off, locate the thin metal temperature sensor probe inside the oven (usually on the back wall, upper area). Remove the mounting screws and gently pull the sensor forward to access the connector. Check for burnt or broken wires.
• Test sensor resistance: Using a multimeter set to ohms, measure resistance across the sensor leads at room temperature. A typical 1000–1100 Ω reading at ~70°F (21°C) is expected. If reading is open, shorted, or far out of range, replace the sensor.
• Check harness to control: If the sensor tests good, inspect the wiring from the sensor to the electronic oven control (EOC) behind the control panel. Look for pinched, melted, or loose connectors and repair as needed.
• Replace control board: If wiring and sensor are good but F2 persists or elements stay on, the EOC relay is likely stuck. Replace the electronic oven control board following the model-specific wiring diagram.

Do not continue using the oven if it overheats; this is a fire hazard. Seek professional service if you are unsure about electrical testing.
