According to Costco, I bought that air fryer somewhere else....maybe.

Either way, I took it apart and it was surprisingly clean. Removed the entire door sensor and hard-wired the door sensor so no more problems there. Looks like the errors on the door sensor all internal. I was going to take it apart but felt fulfilled and toss it in the trash. There is still a short with the toaster timer and air fry setting. Also, wont power on if in "air fry" mode. The fan is running high in Bake w/ fan so I'll take it.

All in all, about 40 minutes AND I'll be able to make toast tomorrow.

Thanks for everyone's previous input. I wouldn't have figured out about the screws in 2 of the 4 feet without the tips above

Mine's doing the same thing, sometimes I have to slam the door or flick the door switch repeatedly before it turns on, then it won't turn off, then it wont turn on, then it turns off while cooking...very unpleasant. I bought mine at Costco over two years ago. Costco has a ridiculous return policy and I'm going to take it back and see if this is returnable, then probably buy the same one again! I really like it. If they wont take it, I will either try to pry everything apart as described above and replace the switch or use a wire nut or solder to keep it in the "on position.

For what it's worth, I tried white vinegar and steam cleaning from the outside, no luck.

Also, you are supposed to use the timer on the left for everything except toast, then the toast timer for toasting. Right now, the toaster setting will enable air fry to work too. My guess is there is some or short in multiple places, maybe the sensor and the "mode" selector?

I'm glad I'm not the only one with this problem. Found other cases online. I feel like returning to Costco so they can return to MFG is the best way to make sure Cuisinart learns and fixes this on future models.
