Possible Causes

Failed internal NTC sensor on PCB, Loose sensor harness, Overheating of control area, Defective main PCB

How to Fix / Troubleshooting

Safety first: Turn OFF power to the range and allow it to cool.

Ventilation and environment:

  • Ensure the range is not installed too tightly against cabinetry, restricting airflow.
  • Check that vents are not blocked by foil or other materials.

Internal inspection (advanced):

  • Remove the rear control panel cover.
  • Locate the internal temperature sensor (often mounted near the control board) and verify the connector is secure.
  • Inspect for signs of overheating or melted plastic around the control area.

Next steps: If the sensor is integrated into the PCB or tests out of spec, the main PCB assembly will need replacement. This is typically a professional repair.
