Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the microwave before removing any panels.
Initial steps:
- Unplug for 5–10 minutes to clear the code.
- Plug back in and observe whether F7 appears without pressing any buttons. If so, a key is likely stuck or the keypad matrix is shorted.
Keypad inspection:
- Clean the keypad surface with a soft, slightly damp cloth. Avoid excessive moisture.
- Remove the control panel to access the keypad ribbon cable. Inspect for damage or corrosion and reseat the connector.
Functional test:
- With the panel reinstalled and power restored, test each keypad function.
- If certain keys do not respond or trigger F7, the keypad or user interface board is defective.
Corrective action:
- Replace the membrane keypad or user interface control panel assembly as specified for your model.
- If a new keypad does not resolve F7, the main control board may also need replacement.
