KitchenAid Keypad Membrane Wear or UI Failure

Microwave keypad buttons are unresponsive or respond intermittently; sometimes only certain keys fail.

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

Worn keypad membrane contacts, cracked user interface board, loose ribbon cable, liquid damage from cleaning sprays

Safety: Unplug the microwave before removing the control panel.

Test all keys: Note which keys fail to respond to help identify if the issue is localized or general.
Clean surface: Wipe the keypad with a slightly damp cloth; avoid spraying cleaner directly on the panel.
Inspect ribbon cable: Remove the control panel and reseat the keypad ribbon cable at the control board.
Replace keypad/UI: If specific keys remain dead, replace the keypad membrane or the entire user interface assembly, depending on your model's design.
