Oven displays F3 and will not start or stops mid-cycle; temperature may be inaccurate.

Safety First: Disconnect power at the breaker before accessing wiring or control components.

• Access the sensor: Inside the oven cavity, locate the temperature sensor on the rear wall. Remove its mounting screws and gently pull it forward to access the connector.
• Check connections: Inspect the sensor plug and wiring for burns, corrosion, or broken conductors. Reseat the connector firmly.
• Measure resistance: With the sensor unplugged, use a multimeter to measure resistance across the sensor leads. At room temperature, it should be ~1080–1100 Ω. An infinite or extremely high reading indicates an open sensor.
• Inspect harness to control: If the sensor tests good, trace the harness back to the electronic oven control board. Check for pinched or broken wires, especially where they pass through the rear insulation.
• Replace faulty component: Replace the oven temperature sensor if open. If wiring and sensor are good, replace the electronic oven control board due to a failed sensor input circuit.
• Test operation: Restore power and run a bake cycle at 350°F, verifying that the oven heats and no F3 code reappears.
