Possible Causes

Loose AC input connection, Overheating causing thermal fuse to open intermittently, Faulty power relay on PCB

How to Fix / Troubleshooting

Safety first: Unplug the cooker before inspection.

  • Check power cord and plug: Wiggle the plug gently in the outlet (with another appliance) to rule out a loose outlet. Inspect the cord for damage.
  • Ventilation: Ensure the cooker is not overheating due to blocked vents. Move it to a cooler, open area.
  • Internal wiring check (advanced): Remove the bottom cover and inspect AC input terminals, thermal fuse connections, and relay solder joints for looseness or cracks.
  • Resolder or replace: Repair cracked solder joints on the relay or connectors. Replace a weak thermal fuse or failing relay as needed.
  • Monitor operation: After repair, run a long program with water only and observe whether the cooker completes the cycle without shutting off.
