Step 2: Remove and Clean the Basket and Tray
- Remove the basket and tray from the air fryer.
- Wash them thoroughly with warm, soapy water to remove grease, food particles, and residue.
- Dry completely before reassembling.
Residual grease or food particles can ignite and cause smoke during operation, so regular cleaning is crucial.
Step 3: Check and Clear Vents and Heating Elements
- Inspect the air vents and heating elements for grease or food debris.
- Use a soft brush or cloth to gently clean these parts, ensuring no buildup remains.
- Be cautious not to damage the heating element.
Blocked or dirty vents can cause overheating and smoke. Regular checks help prevent this.
Step 4: Use Liners and Avoid Overfilling
Using compatible liners (like the Cosori liners) can prevent grease from staining the basket and reduce smoke risk. Ensure the basket isn’t overfilled; leave space for hot air circulation to avoid excess grease dripping and burning.
Step 5: Prevent Preheating with Food or Liners
Never preheat the air fryer with empty basket or liners alone, as this can cause smoke. Always add food or properly arranged liners before turning on the device.
