How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
- Step 1 – Clean panel surface: Wipe the keypad with a soft, slightly damp cloth and then dry thoroughly. Do not spray cleaner directly onto the panel.
- Step 2 – Power reset: Unplug the microwave for several minutes and reconnect to clear temporary glitches.
- Step 3 – Inspect ribbon cable: Remove the control panel and check the flat ribbon cable from the keypad to the control board. Reseat the connector and ensure it is fully inserted.
- Step 4 – Check for moisture: Look for condensation or corrosion on the keypad connector. Allow to dry completely if moisture is present.
- Step 5 – Replace keypad or UI board: If specific keys or entire sections of the keypad do not respond, replace the membrane keypad or the complete UI assembly as specified for your Bertazzoni model.
