Possible Causes

Insulation breakdown in heating element, Pinched or bare heater wire touching metal chassis, Moisture inside base causing leakage current, Shorted control board component on heater circuit

How to Fix / Troubleshooting

Safety first: Unplug immediately if the breaker trips. Do not repeatedly reset a breaker without finding the cause.

  • Dry the unit: If the cooker recently overflowed or was washed aggressively, allow it to dry for 24–48 hours in a warm, dry place before retesting.
  • Inspect wiring: Remove the bottom cover and look for any wires with damaged insulation touching the metal frame. Repair or replace as needed.
  • Check heating plate: Look for cracks, burn marks, or melted insulation around the heating plate terminals.
  • Smell test: If you smell burnt electronics, the control board may have a shorted component and should be replaced.
  • Do not bypass ground: Never remove the ground pin from the plug or defeat safety grounding to stop tripping; this is dangerous.
  • Professional evaluation: Because this involves potential shock hazards, consider having a qualified technician perform insulation resistance tests and repairs.
