Error Code F20

Overheat or runaway heat condition detected in the oven. In normal cooking mode, indicates temperature exceeding 650°F (343°C). During self-clean mode, indicates temperature over 915°F (491°C).

? What Causes This

Defective temperature sensor, faulty sensor wiring harness with corroded or loose connections, malfunctioning cooling fan, or defective Electronic Range Control (ERC).

✓ How to Fix It

  1. Measure the temperature sensor's resistance at room temperature (should be approximately 1100 Ω).
  2. If resistance is significantly higher (e.g., 1600 Ω), replace the sensor.
  3. Inspect wiring between sensor and ERC for defects and corrosion.
  4. Check cooling fan operation.
  5. If steps 1-4 don't resolve the issue, replace the ERC.
