Possible Causes

Open oven temperature sensor (RTD), Broken sensor wiring, Loose connector at sensor or control board, Sensor harness unplugged during previous repair

How to Fix / Troubleshooting

Safety first: Disconnect power at the breaker before testing.

  • Access sensor: Remove the oven's rear panel to access the sensor connector, or remove the sensor from inside the cavity and pull it forward to reach the plug.
  • Test sensor resistance: With the sensor unplugged, measure resistance at room temperature. An infinite reading indicates an open sensor; replace it.
  • Check harness continuity: If the sensor is good, test continuity from the sensor connector to the EOC connector using a multimeter. Repair or replace any open wires.
  • Reseat connectors: Firmly reconnect the sensor harness at both ends.
  • Replace parts as needed: Install a new oven temperature sensor if open. If wiring and sensor are good, the electronic oven control board may be misreading the circuit.
