Common Reasons Why Your Cosori Air Fryer Fan Isn’t Working

The Cosori air fryer uses a fan to circulate hot air, cooking food quickly and evenly. When the fan stops working, it usually points to one of several common issues. Here’s a breakdown of potential causes:
Overheating Issues
Modern air fryers have built-in safety features to prevent overheating. If the unit gets too hot, the fan might automatically shut down to prevent further damage.
- Solution: Let the air fryer cool down completely before attempting to use it again. Ensure that the vents are not blocked and that the air fryer is placed in an area with sufficient ventilation.
Obstructions
Food debris or grease buildup can sometimes obstruct the fan, preventing it from spinning freely.
- Solution: Unplug the air fryer and carefully inspect the fan area. Remove any visible obstructions using a soft brush or vacuum cleaner attachment. Regular cleaning can prevent this issue.
Control Panel Problems
Sometimes, the issue lies within the control panel or the settings you’ve selected.
- Solution: Ensure the air fryer is set to a mode that activates the fan. Some models have specific settings for different types of food that might affect fan operation. Try resetting the air fryer by turning it off and unplugging it for a few minutes before plugging it back in.
Electrical Issues
A faulty power cord, a blown fuse, or other electrical problems can prevent the fan from receiving power.
- Solution: Check the power cord for any signs of damage and ensure it is properly connected to the air fryer and the outlet. If the air fryer has a fuse, check if it needs replacement. For more complex electrical issues, consult a qualified technician.
Motor Problems
The fan motor itself might be defective or worn out, especially in older units.
- Solution: Unfortunately, motor replacement can be complex and sometimes not cost-effective. Contact Cosori customer support to inquire about repair options or warranty coverage.

Inspect and Clean the Fan Area:
Unplug the air fryer and allow it to cool down.

Test the Overheat Protection:
If you suspect the air fryer has overheated, let it cool down completely.
- Ensure the vents are clear and the unit has proper ventilation.
- Try using the air fryer again after it has cooled down to see if the fan operates normally.
