Possible Causes

Shorted or misreading NTC sensor, Stuck heater relay, Faulty thermostat or thermal cut-out not opening at correct temperature, Sensor dislodged from correct position

How to Fix / Troubleshooting

Safety first: Unplug and allow to cool fully.

Steps:

  • Sensor position: Verify that the cavity temperature sensor is properly clipped in place and not touching the heater directly.
  • Sensor test: Measure NTC resistance at room temperature and compare to expected values. Replace if out of range.
  • Relay check: On the main board, check if the heater relay is stuck closed (heater always on). If so, replace the board or relay.
  • Thermal safety: Confirm that the thermal cut-out opens at its rated temperature by testing continuity after a controlled heat test (service procedure).

Warning: Overheating can lead to fire; do not continue using the unit until the fault is corrected.
