This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Warped inner pan causing uneven contact, Foreign object under inner pan, Loose internal components, Failing relay on control board

Safety first: Unplug and allow to cool before inspecting inside.

Remove and inspect pan: Check the underside of the inner pan and the heating plate for foreign objects (spoons, grains, etc.).
Check pan flatness: Place the pan on a flat surface to see if it rocks. Replace if warped.
Normal relay clicks: Occasional soft clicks can be normal as relays switch; continuous loud buzzing is not.

When to call a technician: Persistent loud buzzing or grinding from inside the body indicates internal component issues.
