Error E2
Cosori Air Fryer
Severity:What Does This Error Mean?
Cosori E2 means the internal fan motor has stopped or failed. The fan circulates hot air for even cooking — without it, the unit will not cook correctly. Check that the basket is correctly seated, as some models trigger E2 when the basket is not fully inserted.
Affected Models
- Cosori Pro II 5.8 Qt
- Cosori Pro Gen 2 5 Qt
- Cosori Dual Blaze
- Cosori Smart WiFi Air Fryer
- Most Cosori air fryer models
Common Causes
- Fan motor failed or seized
- Fan blade blocked by food debris
- Basket not correctly seated triggering a safety interlock
- Overheat cutoff stopping the fan
- Fan motor connector loose
How to Fix It
-
Ensure the basket is fully inserted and clicked into place.
Some Cosori models use a basket presence sensor. A basket not fully seated triggers E2 as a safety measure. Push the basket in firmly until you hear the click.
-
Unplug the air fryer and allow it to cool completely.
An overheating event can trip the fan motor's thermal protection. Wait 30 minutes, plug back in, and test.
-
Check for visible food debris in the air vents.
Food particles can enter the fan housing through the rear vents and block the fan blade. Use a toothpick to clear any debris visible in the vent slots — do not use water.
-
Test with a short cook cycle after cooling.
Set to 160°C for 3 minutes. You should hear the fan spinning within 10 seconds of starting. If you hear nothing, the fan motor is not responding.

Contact Cosori support for warranty service.
E2 from a failed fan motor requires internal repair. Have your model number (on the bottom label) and proof of purchase ready when contacting support.
When to Call a Professional
E2 requires internal inspection to access the fan. Do not open the air fryer yourself. Contact Cosori support — fan motor replacement under warranty is available on most models.
Frequently Asked Questions
What does E2 mean on a Cosori air fryer?
E2 indicates a fan motor fault. The fan circulates hot air to cook food evenly. An E2 means the fan is not spinning — the unit will not cook safely and should not be used.
Can I fix Cosori E2 myself?
Not safely. The fan motor is inside the sealed unit. Opening the air fryer voids the warranty and risks electrical hazards. Contact Cosori support for warranty repair.
