How to Fix / Troubleshooting
Safety first: Unplug the microwave before working on the control panel.
- Clean keypad surface: Wipe the keypad with a slightly damp cloth and mild detergent. Do not allow liquid to seep into the edges.
- Test multiple keys: Note whether all keys are affected or only certain areas. Localized failure suggests membrane wear.
- Inspect ribbon cable: Remove the control panel and check the keypad ribbon for cracks or kinks. Reseat it on the UI board.
- Replace keypad assembly: If keys remain unresponsive, replace the keypad or entire control panel assembly with the correct Fisher & Paykel part.
