Morphy Richards Keypad Wear / Membrane Failure

Microwave buttons are unresponsive or require very hard pressing to register.

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 contacts, Cracked keypad ribbon cable, Contamination under keypad overlay, Faulty control PCB key scan

Steps:

1. Clean surface: Wipe the keypad with a soft, slightly damp cloth to remove grease and dirt.
2. Test multiple keys: Note which keys fail. If entire rows or columns are dead, the ribbon or PCB may be at fault.
3. Reseat ribbon cable (for competent persons): Remove the control panel and reseat the keypad ribbon on the control PCB.
4. Replace keypad: If individual keys remain unresponsive, replace the membrane keypad or full control panel assembly.
