Smoking
Ninja Air Fryer
Severity: ModerateWhat Does This Error Mean?
Your Ninja air fryer is producing smoke during cooking. This is almost always caused by excess grease or food residue burning on the heating element or the bottom of the unit — not a fault with the appliance itself. It is normal for a small amount of steam to appear, but visible smoke means cleaning is needed.
Affected Models
- Ninja AF101
- Ninja AF161
- Ninja DZ201 DualZone
- Ninja SP101 Foodi
- Ninja AF080
Common Causes
- Grease buildup on the heating element from previous cooks
- Fatty foods (bacon, sausages) dripping excess grease
- Food residue stuck to the basket or crisper plate
- Cooking spray residue baked onto the basket coating
- New unit burning off factory coating on first use (normal)
How to Fix It
-
If smoking heavily, turn off and unplug the unit immediately.
Light wisps of steam are normal. Thick smoke, especially with a burning smell, means you should stop cooking right away.
-
Let the unit cool, then remove and wash the basket and crisper plate with warm soapy water.
Grease that builds up over multiple cooks is the main cause of smoking. A thorough wash after each use prevents it.
-
Wipe the inside of the cooking chamber and the heating element area with a damp cloth.
Do not submerge the main unit. Use a damp cloth to wipe away any splattered grease from the chamber walls.
-
For fatty foods, add a small amount of water (2 tablespoons) to the bottom of the basket before cooking.
The water catches dripping grease and prevents it from burning on the heating element below. Works well for bacon and sausages.
-
Avoid aerosol cooking sprays — they leave a residue that burns and smokes.
Use a brush to apply a thin layer of oil instead of spray. Aerosol sprays are the number one cause of basket coating damage and smoking.
When to Call a Professional
Smoking from the exhaust vent is almost never a hardware fault — cleaning resolves it in virtually every case. If you see sparks or smell burning plastic, unplug immediately and contact Ninja support.
Frequently Asked Questions
Is it normal for a new Ninja air fryer to smoke on first use?
Yes — a small amount of smoke and an unusual smell during the first 1-2 uses is completely normal. The protective coating applied during manufacturing burns off. Run the unit empty at 400F for 10 minutes before your first cook to burn this off safely.
Can I use my Ninja air fryer if it smokes a little?
A very small amount of vapour from cooking juices is normal and safe. Visible white or grey smoke from the exhaust vent means you should clean the unit before continuing. Black smoke or a burning plastic smell means stop immediately and unplug.
