How to fix it

  1. Disconnect power at the breaker.
  2. Pull the oven out and disconnect the sensor harness at the back.
  3. Measure resistance across the sensor — should read about 1080 ohms at room temperature (72F).
  4. If resistance is open (OL) or wildly off, replace the oven temperature sensor.
  5. Inspect the harness for damaged insulation or corroded pins.
  6. If the sensor reads correct, replace the control board.

Why it happens

  • Failed temperature sensor RTD probe has gone open — out of spec resistance.
  • Broken or disconnected sensor wire Wire harness pulled loose at the rear or connector corroded.
  • Failed control board Sensor input on the EOC has failed.
