Display shows F3 and beeping; oven will not start or stops mid‑cycle.

Safety first: Disconnect power at the breaker before accessing the sensor or control board.

• Access the sensor: Inside the oven cavity, locate the temperature sensor on the rear wall. Remove the mounting screws and gently pull the sensor forward.
• Check connector: Disconnect the sensor plug and inspect for corrosion or loose pins. Clean with contact cleaner if needed and reconnect firmly.
• Measure resistance: With the sensor unplugged, measure resistance across its terminals. If the reading is infinite (open circuit) or extremely high, the sensor is defective and must be replaced.
• Check harness continuity: If the sensor tests good, check continuity from the sensor connector to the EOC connector using a multimeter. Repair or replace any open or damaged wires.
• Replace parts: Replace the oven temperature sensor if open. If sensor and wiring are good but F3 persists, replace the electronic oven control (EOC).
