Oven displays F3E0 and stops heating; usually associated with the main oven cavity.

Safety first: Turn off power at the breaker before testing.

• Locate sensor: Find the main oven temperature sensor on the rear wall inside the oven. Remove mounting screws and gently pull sensor forward.
• Test sensor: Disconnect the sensor plug and measure resistance at room temperature (~1080–1100 Ω). If reading is open, shorted, or far out of spec, replace the sensor.
• Inspect harness: Check the harness from the sensor to the control for cuts, burns, or pinched sections. Repair or replace as needed.
• Control board: If sensor and wiring are good, the sensor input on the electronic oven control board may be defective and require replacement.
