Technician Only Test and replace temperature sensor or wiring

  1. Disconnect power and remove the oven’s access panel.
  2. Inspect the temperature sensor and its wiring for damage, loose connections, or shorts.
  3. Measure the resistance of the temperature sensor with a multimeter and compare to manufacturer specs.
  4. Replace the sensor or repair wiring if readings are out of specification or if physical damage is found.
  5. Reassemble and test the oven for normal operation.

Parts needed: Temperature sensor (thermistor/PT sensor), Wiring harness/connectors
