Possible Causes
Failed control PCB, Corrupted firmware, Shorted keypad matrix, Loose keypad connector
How to Fix / Troubleshooting
Safety first: Unplug the microwave before accessing the control area.
Step-by-step checks:
- 1. Power cycle: Unplug for 5–10 minutes, then plug back in. If F1 returns immediately, the fault is persistent.
- 2. Reseat keypad connector: Remove the control panel and reseat the keypad ribbon cable on the control board.
- 3. Inspect for damage: Look for burnt or damaged components on the control PCB.
- 4. Replace parts: If reseating does not help, replace the keypad assembly first. If F1 persists, replace the main control board with the correct Midea part.
