Technician Only Inspect and test the temperature sensor and circuitry

  1. Disconnect power to the oven at the circuit breaker.
  2. Access the temperature sensor (thermistor) inside the oven cavity.
  3. Visually inspect for damage, disconnection, or burn marks.
  4. Use a multimeter to measure the sensor’s resistance and compare to manufacturer specification.
