Possible Causes

Corrupted control board firmware, Failed memory (EEPROM) on PCB, Power surge damage, Loose ribbon cable between display and main board

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.
