KitchenAid Phantom Key Press / UI Contamination

Microwave keypad beeps randomly or starts functions by itself without pressing buttons.

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

Moisture or steam behind keypad, liquid spill into control panel, failing keypad membrane, failing user interface board

Safety: Unplug the microwave immediately if it starts by itself.

Dry out panel: Leave the microwave unplugged for several hours to allow any moisture behind the keypad to evaporate.
Avoid sprays: Do not spray cleaner directly on the control panel; apply to a cloth instead.
Inspect UI: If the problem persists, remove the control panel and inspect for signs of liquid damage or corrosion.
Replace keypad/UI: Replace the keypad membrane or user interface board if contamination or failure is evident.
