Possible Causes

Sensor partially out of cavity, Sensor wiring high resistance, Control board miscalibration, Incorrect rack or tray placement too close to element

How to Fix / Troubleshooting

Safety: Verify temperature with an independent thermometer before making adjustments.

  • 1. Confirm overheat: Use an oven thermometer to compare actual and set temperatures at 180°C.
  • 2. Inspect sensor position: Ensure the sensor probe is fully inserted into the cavity and not pulled back into the wall, which can cause false readings.
  • 3. Check wiring: Inspect the sensor harness for poor connections or corrosion at the control board connector.
  • 4. Adjust offset: If your model supports it, apply a negative temperature offset in the settings menu.
  • 5. Replace sensor or board: If the error is large and persistent, replace the sensor first; if still incorrect, the control PCB may need replacement.
