Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the air fryer before opening the housing. Static discharge can damage electronics; ground yourself before touching the board.
Steps to address E9:
- Power cycle: Unplug the unit for at least 10 minutes to allow capacitors to discharge. Plug back in and test. If E9 persists, continue.
- Inspect control PCB: Remove the top or front panel to access the main control PCB and display board. Look for burn marks, swollen components, or corrosion.
- Check ribbon cables: Ensure any ribbon or plug‑in cables between the display and main board are fully seated. Disconnect and reconnect them to clean contacts.
- Surge damage signs: If there are signs of lightning or surge damage (charred tracks, blown components), the board will need replacement.
- Board replacement: Replace the entire Pro Breeze air fryer main control PCB with an identical part number. Transfer any mounting hardware and reconnect all harnesses exactly as original.
Warning: Board‑level component repair is not recommended for untrained users. Incorrect repair can create shock hazards.
