Seeing white smoke coming out of your air fryer can be alarming, especially if it happens suddenly during cooking. At Appliance Medic Pro, we frequently get calls from homeowners who think their air fryer is about to catch fire β but in many cases, the issue is preventable.
Still, white smoke should never be ignored, as it can indicate grease buildup, overheating, or electrical issues.

Is White Smoke From an Air Fryer Dangerous?
Sometimes β yes.
From real service experience:
-
Light white smoke often comes from burning grease or food residue
-
Heavy or continuous smoke may indicate overheating or electrical failure
If smoke continues after turning the unit off, unplug it immediately.
Common Reasons an Air Fryer Is Producing White Smoke
1. Grease or Oil Dripping Onto the Heating Element (Most Common)
This is the #1 cause we see.
It happens when:
-
Cooking fatty foods (bacon, chicken wings, sausages)
-
Excess oil pools in the bottom
-
Drippings hit the hot heating element
π This creates white or light gray smoke, often with a burnt smell.
2. Food Residue or Old Grease Buildup
If the basket or tray isnβt cleaned regularly:
-
Old grease reheats and burns
-
Smoke appears early in the cooking cycle
-
Smell is strong but not electrical
We see this often in air fryers used daily without deep cleaning.
3. Using Too Much Oil
Air fryers require very little oil.
Using excess oil can:
-
Overflow into the base
-
Smoke when heated
-
Leave residue on internal parts
4. New Air Fryer (Burn-In Period)
Brand-new air fryers may produce smoke due to:
-
Manufacturing oils are burning off
-
Protective coatings heating for the first time
This usually disappears after 1β2 uses.
5. Overheating or Electrical Component Issue (Serious)
If smoke:
-
Smells like burning plastic
-
Is thick and continuous
-
Appears with buzzing or popping sounds
β οΈ This may indicate wiring or control board failure and should be inspected by a professional.
What You Should Do Immediately
If you see white smoke:
β
Turn the air fryer OFF
β
Unplug it from the outlet
β
Allow it to cool completely
β
Remove food and basket
β
Inspect for grease buildup
β Do NOT pour water inside
β Do NOT continue cooking if smoke persists
How to Fix and Prevent White Smoke in an Air Fryer
From technician experience:
-
Clean the basket, tray, and base after greasy foods
-
Use parchment liners (air-fryer safe)
-
Add a little water to the drip tray when cooking fatty foods
-
Avoid aerosol cooking sprays (they leave residue)
-
Do not overfill the basket
When to Stop Using the Air Fryer and Call a Professional
Contact Appliance Medic Pro if:
-
Smoke smells electrical or plastic-like
-
Smoke continues with no food inside
-
Unit shuts off unexpectedly
-
Controls stop responding
Continued use in these cases can create fire or shock hazards.
