How to Fix / Troubleshooting
Safety first: Unplug before internal inspection. Avoid using damaged cords.
- Direct connection: Plug the cooker directly into a wall outlet without extension cords or multi-plugs.
- Inspect cord: Replace the power cord if it is thin, damaged, or non-original.
- Internal connection check (advanced): Inspect screw terminals and solder joints on the AC input and neutral bus. Tighten and resolder as needed.
- Check capacitors: Look for bulging or leaking electrolytic capacitors in the SMPS section. Replace the PCB if capacitors are failing.
- House wiring: If multiple appliances flicker, consult an electrician to check household wiring and voltage stability.
