How to Fix / Troubleshooting
Safety first: Unplug before opening the unit.
Basic checks:
- 1. Dedicated outlet: Plug the air fryer into a dedicated wall outlet, not a power strip with other high‑load devices.
- 2. Cord inspection: Check the power cord for damage or loose fit in the outlet.
Internal checks (advanced):
- 3. Control board capacitors: Open the housing and inspect the power supply section of the control board. Look for bulging or leaking electrolytic capacitors.
- 4. Reseat connectors: Ensure all low‑voltage connectors to the display and UI board are firmly seated.
- 5. Replace board: If capacitors are failing or voltage is unstable, replace the control board.
