What to check, in order
- Unplug it and let it cool
Completely.
- Clean it out
Clean the basket area and the vents thoroughly. Baked-on grease around the fan is a frequent culprit.
When to call an engineer
If it's clean and the fan still grinds or won't spin, the motor has worn out.
Good to know
- Air fryer makers use these codes less consistently than other appliances. If your manual says something different, the manual wins.
About this code
Unbranded and less common appliances don't publish one shared code list, so this page gives the most common meaning across makers. Your manual is the final word, and the model number that finds it is on a label on the underside.
