Café Keypad / Membrane Failure

Microwave keypad buttons are unresponsive or require very hard presses; some keys work while others do not.

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 membrane keypad, Cracked control panel overlay, Loose keypad ribbon cable, Liquid damage to keypad

Safety first: Unplug the Café microwave.

Steps to try:

Test all keys: Note which keys work and which do not. If entire rows or columns fail, the keypad matrix is likely damaged.
Clean surface: Wipe the keypad with a soft, slightly damp cloth and dry thoroughly. Do not spray cleaner directly on the panel.
Power reset: Restore power and test again.
Repair: The long-term fix is to replace the keypad or full control panel assembly. This involves removing the top grille and control panel and transferring the wiring harness.
