Interior light (on models equipped with a viewing light) does not turn on, but the unit heats and cooks normally.

Safety first: Unplug the air fryer and allow it to cool before accessing the lamp area.

Steps to restore interior lighting:

• 1. Confirm function: Verify that all other functions (heating, fan, timer) work normally. If only the light is out, the issue is likely limited to the lamp circuit.
• 2. Access the lamp: On Hamilton Beach models with a viewing window, the lamp is usually behind a small glass or plastic lens inside the cavity or behind the side panel. Remove the appropriate cover screws.
• 3. Inspect the lamp and wiring: Look for a visibly burned or darkened LED module or bulb. Check that the lamp connector is firmly seated.
• 4. Replace the lamp module: If the lamp appears damaged or does not light when the unit is on, replace it with the correct Hamilton Beach lamp/LED module for your model.
• 5. Check the driver circuit (advanced): If a new lamp does not work, the lamp driver on the control board may have failed. Inspect the board for damage and replace the board if necessary.

Note: Use only manufacturer‑approved replacement lamps or LED modules to avoid overheating or electrical issues.
