Sharp oven shows F14 and may not start pyrolytic self-clean or high-heat modes.

Safety: Ensure the oven is cool and power is off before inspection.

• Check door lock status: Confirm that the door lock engages properly when starting self-clean. If the door does not lock, address the door lock assembly first.
• Locate pyrolytic sensor/thermostat: On pyrolytic models, there may be a dedicated high-temperature sensor or thermostat. Test for continuity or correct resistance per service specs.
• Inspect wiring: Trace the self-clean circuit wiring from the control board to the lock and high-limit devices. Repair any damaged or overheated wires.
• Replace faulty components: Replace the pyrolytic sensor or thermostat if open or out of spec. If all components are good, the control board may be misreading the circuit and require replacement.
