F7 — Stuck key on function keypad
F7 means the control sees a key on the touch / membrane keypad held down for too long (typically more than ~60 seconds). The microwave locks out cooking until the key is released or the keypad is replaced.

How to fix it
- Unplug the microwave for 5 minutes, then restore power — if F7 clears and stays clear, you're done.
- Inspect the keypad surface for bulges, sticky residue, or moisture.
- Gently clean the keypad face with a damp cloth and mild detergent — never spray cleaner directly.
- If F7 returns, unplug and disconnect the keypad ribbon at the control to confirm the fault is in the keypad (F7 should change to a 'no keypad' fault).
- Replace the membrane touch pad / control panel with the OEM part for your model.
- If a new keypad still throws F7, replace the control board.
Why it happens
Typical signs: F7 displayed, beeping · One pad may feel sticky, bulged, or unresponsive · Pressing CLEAR/OFF does nothing · Code returns shortly after reset
- Grease or moisture under the membrane keypad Contamination shorts a key continuously.
- Physically damaged / bubbled keypad Heat or impact has deformed the membrane so a key is always pressed.
- Damaged keypad ribbon or trim A crimp from the trim screws can pinch the tail.
- Control board input failure Only suspect after a new keypad still triggers F7.
