How to Fix / Troubleshooting
Safety: Unplug the microwave before any disassembly.
Steps:
- 1. Power reset: Unplug for 10–15 minutes, then reconnect. If F1 clears and does not return, it may have been a transient glitch.
- 2. Check for moisture: If F1 appeared after heavy steaming, allow the control area to dry thoroughly.
- 3. Inspect control board: Remove the control panel and visually inspect the PCB for burnt components or corrosion. If damage is visible, replace the board.
- 4. Replace control board: If F1 persists with no visible damage, the control PCB is likely faulty and should be replaced with a Galanz-compatible board.
