Possible Causes
Open low-power heating circuit on PCB, Faulty relay or triac controlling keep-warm, Broken wiring to auxiliary heater (if present), Firmware error in warm mode control
How to Fix / Troubleshooting
Safety first: Unplug the cooker before opening the base or control housing.
- Check wiring: Inspect all heater wires from the control board to the heating element. Some models use separate taps or circuits for keep-warm; look for loose connectors.
- Inspect PCB components: Identify the relay or triac dedicated to keep-warm (refer to board markings). Look for burn marks or cracked solder joints and resolder if needed.
- Functional test: If you can safely measure voltage, check whether the board outputs reduced power to the heater in warm mode. No output suggests a control fault.
- Board repair or replacement: Replace the faulty relay/triac or the entire control board if component-level repair is not feasible.
