Nuwave air fryer interior light (if equipped) does not turn on, but unit otherwise works.

Safety First: Unplug the air fryer and allow it to cool before accessing the light assembly.

Step-by-step checks:

• Confirm feature: Verify that your specific Nuwave model includes an interior light and that you are using the correct button or function to activate it.
• Inspect lens: Check the light lens for cracks or heavy grease buildup that may make it appear dim.
• Access light (advanced): With the unit unplugged and cover removed, locate the interior light module near the top of the cavity. Check the wiring connector for a secure fit.
• Test voltage: During a light-on command (use caution and proper insulation), measure voltage at the light connector. If voltage is present but the light is off, the LED/bulb is bad.
• Replace module: Replace the interior light assembly if defective. If no voltage is present, the main control board light driver may have failed.

Note: Light failure does not affect cooking performance but can be inconvenient; repair based on your comfort level.
