Possible Causes

Normal relay switching on PCB, Inner pot expanding and contracting, Slight movement of heating plate, Loose mounting screws

How to Fix / Troubleshooting

Safety first: Unplug the cooker before tightening any screws.

  • Identify noise source: Light clicking from inside the housing at intervals is often the heater relay and is normal. Loud metallic pops from the base or pot may indicate mechanical movement.
  • Tighten base screws: Remove the bottom cover and gently tighten mounting screws for the heating plate and chassis.
  • Check inner pot fit: Ensure the pot sits flat and does not rock. A slightly warped pot can make popping sounds as it flexes.
  • Monitor for burning smell: If noise is accompanied by smell or smoke, stop using the cooker and inspect for overheating components.

Note: Some clicking is normal; focus on new, unusually loud, or grinding noises.
