Nuwave air fryer emits a strong burning plastic or electrical smell during use.

Safety First: If you smell strong burning plastic or see smoke (other than minor cooking smoke), unplug the air fryer immediately and do not continue using it.

Step-by-step checks:

• New unit break-in: For a brand-new Nuwave air fryer, a light odor during the first 1–2 uses can be normal. Run an empty cycle at 400°F for 10–15 minutes with good ventilation to burn off manufacturing residues.
• Inspect interior: Once cool, check inside the basket area and around the heating element for any plastic packaging, zip ties, or utensils that may have been left inside and melted.
• Check wiring (advanced): With the unit unplugged and cover removed, inspect wiring near the heater and control board. Look for melted insulation, darkened connectors, or scorched PCB areas.
• Repair damage: Replace any burnt wiring harnesses and damaged connectors. If the control board shows burn marks, replace the main control board.

Warning: Do not ignore persistent burning smells. They indicate a potential fire hazard and must be addressed before further use.
