my ninja air fryer is smoking a lot, not just a little steam, should i unplug it?

Yes. Unplug it immediately from the wall outlet. Black smoke indicates a serious issue.

1. Wait for all smoking to stop.
2. Let the appliance cool completely.
3. Inspect for burnt food debris or oil spillage inside the unit or on the heating element.

If that didn't work: The unit may be damaged. Do not use it again. Return the appliance to SharkNinja Operating LLC for examination, repair, or adjustment.

Heads up: Never use this appliance for deep-frying with oil. Never cover the air intake vent or air outlet vent while operating. This causes overheating.
