How to Fix / Troubleshooting

Safety first: Unplug the cooker and allow it to cool before inspection.

  • Check for warmth: During operation, carefully feel the outside of the cooker (without blocking vents). If it remains completely cold, the heater is not energizing.
  • Test different modes: Try sauté and slow cook. If none produce heat, the heater circuit is likely open.

Heater circuit diagnosis involves live electrical testing and should be performed by a qualified technician. The heating element or control board may need replacement.
