Possible Causes
Weak household circuit, Loose power cord connection, Failing low-voltage regulator on main PCB, Oxidized AC input terminals
How to Fix / Troubleshooting
Safety first: Avoid using the cooker on overloaded circuits with other high-wattage appliances.
- Try another outlet: Plug the cooker directly into a different wall outlet on a separate circuit.
- Check cord fit: Ensure the plug fits snugly in the outlet and the cord is fully inserted into the cooker (if detachable).
- Inspect internal connections (advanced): Remove the bottom cover and check that the AC input terminals and neutral/line connections are tight.
- Board replacement: If flickering persists on a good circuit, the main board's power supply may be failing and require replacement.
