How to Fix / Troubleshooting
Safety: Unplug and cool the cooker before tightening any screws.
- Differentiate normal vs abnormal: Occasional soft clicks from relays are normal. Very loud or metallic noises may indicate mechanical issues.
- Check pot and plate: Remove the pot and clean the heater plate. Ensure the pot sits flat and does not rock.
- Tighten heater mounts (advanced): Remove the bottom cover and gently tighten the screws holding the heater to the chassis.
- Inspect for arcing: Look for burn marks or carbon tracking near the heater terminals or relay. If present, stop using the cooker and replace damaged parts.
- Monitor: If noises persist or worsen, have a technician inspect the heater and control PCB.
