Nuwave air fryer emits a persistent bad odor (rancid or chemical) even when not cooking greasy foods.

Safety First: Unplug and cool the unit before cleaning. Avoid harsh chemicals inside the cooking cavity.

Step-by-step checks:

• Deep clean removable parts: Wash the basket, pan, and any removable racks thoroughly with hot, soapy water. Soak if necessary.
• Clean interior: Wipe the interior walls, ceiling, and around the heating element with a cloth dampened with a mild detergent solution. Rinse with a clean damp cloth and dry.
• Deodorize cycle: Place a small dish of water with a few tablespoons of lemon juice in the basket and run the air fryer at 350°F for 10–15 minutes. Allow to cool with the basket slightly open.
• Inspect for burnt plastic: Look for any melted plastic parts or liners that may have been overheated. Replace any deformed components.

Note: Persistent chemical odors after cleaning and deodorizing may indicate previous overheating damage to internal plastics; in such cases, consider professional inspection or replacement of the unit.
