Multicooker makes loud clicking, popping, or buzzing noises during operation beyond normal relay clicks.

Safety first: Unplug the cooker and allow it to cool before inspecting internal areas.

• Identify normal vs abnormal: Occasional soft clicks from relays are normal. Continuous loud buzzing, arcing sounds, or metallic grinding are not.
• Inspect under inner pot: Remove the pot and check for utensils, grains, or debris on the heating plate. Remove any foreign objects.
• Check pot contact: Place the empty inner pot on the plate and gently press down. It should sit flat without rocking. Replace a warped pot.
• Internal inspection (advanced): With the bottom cover removed (unplugged), check that the heating plate mounting screws are tight and that no wires are touching the hot surfaces.
• Stop use if electrical noise persists: Buzzing or crackling from the control board area may indicate a failing relay or arcing. Discontinue use and have the board inspected and replaced if necessary.
