Air fryer beeps repeatedly and will not start, but no specific error code is shown.

Safety first: Unplug before manipulating mechanical parts if needed.

• Check on‑screen prompts: Some models require pressing Start after selecting time and temperature; ensure the full sequence is followed.
• Basket and lid: Remove and reinsert the basket firmly. Open and close the lid until it latches securely.
• Keypad reset: Unplug for 5 minutes to clear any stuck input states. If a button is physically stuck, gently work it free or replace the keypad.
• Interlock switches: Inspect and test basket and lid switches; replace if they do not change state when actuated.
