Possible Causes
Faulty NTC temperature sensor reading too low, Sensor detached from heater housing, Control PCB miscalibration, Fan not distributing heat evenly
How to Fix / Troubleshooting
Safety first: Unplug before internal inspection.
- Use lower settings: Temporarily reduce cooking temperature by 20–30°C (50°F) and increase time to compensate.
- Check sensor mounting: Open the unit and locate the NTC sensor. Ensure it is firmly clipped to the heater housing or designated bracket, not dangling.
- Test sensor: Measure resistance at room temperature and compare to expected values (from service data if available). Replace if out of range.
- Verify fan operation: Ensure the fan runs at full speed; a slow fan can cause hot spots near the heater.
