Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the microwave before removing the control panel.
- Clean keypad surface: Wipe with a soft, slightly damp cloth and mild detergent. Dry thoroughly.
- Power reset: Unplug for 5–10 minutes, then plug back in and test.
- Ribbon cable check (advanced): Remove the control panel and reseat the flat ribbon cable connecting the keypad to the control board. Ensure it is fully inserted and locked.
- Test keys: After reassembly, test all keys. If specific keys still fail, the membrane keypad is likely worn and must be replaced.
- Next step: If no keys respond, the control board may be defective. Consider professional diagnosis.
