Unplug and Allow to Cool
Before starting any troubleshooting, unplug the air fryer and let it cool completely. This ensures safety and prevents burns while cleaning or inspecting components.
Clean the Basket and Interior
- Remove the basket and any accessories. Wash them thoroughly with warm soapy water or use a dishwasher if they are dishwasher safe.
- Check for grease, food residue, or burnt particles stuck on the heating element or inside the basket. Use a soft brush or cloth to gently clean these areas.
- Dry all parts completely before reassembling.
Inspect and Clear Vents and Heating Element
Look for blockages or accumulation of debris near the vents and heating element. Use a soft brush or compressed air to remove dust or grease that could cause smoke.
Check and Use Proper Liners
If using liners, ensure they are placed correctly and not during preheating. Avoid using liners that are too thick or placed in a way that blocks airflow, as this can cause overheating and smoke.
Test and Prevent Future Smoking
- Reassemble the basket and accessories. Plug in the air fryer and run it at a low temperature (around 200°F) for 5 minutes to see if smoke persists.
- If smoke continues, repeat cleaning or consider inspecting the heating element for damage.
- Regular maintenance and cleaning after each use will help prevent future smoking issues.
