Possible Causes

Faulty NTC sensor reading low, Heater relay stuck on, Control board calibration error, Fan not circulating heat evenly

How to Fix / Troubleshooting

Safety first: Monitor the unit closely if you suspect overheating and keep it away from flammable materials.

  • Verify temperature: Use an oven thermometer to compare actual temperature to the set value. If significantly higher, suspect sensor or control issues.
  • Adjust recipes: Temporarily lower set temperatures by 25–50°F and shorten cook times while diagnosing.
  • Inspect sensor: Check that the NTC sensor is properly mounted and not touching the heater directly. Replace if damaged.
  • Control board: If the heater does not cycle off or temperatures overshoot badly, replace the main control PCB.
