Princess Keypad / Touch Panel Failure

Microwave keypad buttons do not respond, or only some buttons work intermittently.

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, Loose ribbon cable connection, Moisture ingress behind control panel, Faulty control PCB scanning circuit

Safety: Unplug before cleaning the control panel.

Clean surface: Wipe the keypad gently with a soft, slightly damp cloth and then dry. Avoid spraying cleaner directly onto the panel.
Drying time: If moisture may have entered, leave the unit unplugged for several hours to dry.
Test all keys: After plugging back in, test each button. If specific rows or columns fail, the membrane or ribbon cable is likely damaged.
Service: Replacement of the keypad membrane or entire control panel assembly is usually required.
