Possible Causes
Failed main heating element under the pot, Open thermal fuse, Faulty triac or relay on control PCB, Disconnected heater wiring
How to Fix / Troubleshooting
Safety first: Unplug the cooker and allow it to cool before inspection.
- Check with simple test: Start a manual high-temperature or sauté program for 5–10 minutes with the empty pot in place. Carefully feel the outside of the cooker body; it should become warm. If it stays cold, the heater is not energizing.
- Listen for clicks: Normally, you may hear a faint relay click when heating starts. Absence of this sound can indicate a control issue.
- Do not attempt DIY rewiring: The heater circuit carries mains voltage and high current.
Diagnosis and replacement of the heating element, thermal fuse, or control PCB must be performed by a qualified technician.
