Check Basket and Accessories
- Ensure the basket is properly seated in the unit. A misaligned basket can cause sensor errors.
- Remove any accessories or liners and verify they are correctly placed and not obstructing sensors or vents.
- Reinsert the basket securely, listening for a click or confirming proper alignment.
Clean Sensors and Contacts
Turn off and unplug your air fryer before cleaning. Use a soft, damp cloth or a cotton swab to gently wipe the temperature sensors located near the heating element and the contact points inside the basket. Dirt or grease buildup can trigger false error codes.
Reset the Air Fryer
- Unplug the device from the power outlet.
- Wait for about 5 minutes to allow internal components to reset.
- Plug the unit back in and turn it on. Check if the error persists.
Inspect for Electrical or Mechanical Damage
If error codes continue, carefully examine the power cord, plug, and internal wiring for signs of damage or loose connections. Do not attempt internal repairs unless qualified. Contact COSORI customer support if you suspect hardware issues that require professional service.
