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.
