Cleaning the air-fryer is another matter. The trays that nicely slide into the supports hold onto grease with great vigor.

Meijers sells non-stick pans designed to sit on top of the original trays. Not quite so large, but Non Stick.

I can live with that.

Living with the handles sticking out just a little wider than my air-fryer isn't quite so easy to live with.

A few minutes on the table saw with an abrasive metal blade, and the tray fits nicely.

A few more minutes with a sander to smooth the razor-sharp edges, and it was safe for use.

I cooked a couple burgers in this and it worked perfectly. Cleanup was just a damp sponge and a rinse. The original pans couldn't be cleaned with Easy-Off and a steel pad.

Being shown how a proper pan behaves embarassed the air-fryer so much it decided to go on strike. I applied percussive maintenance with limited success. "Limited", in this case means none at all.

This required more investigation, which required removing the outer casing, and ignoring the "No User Servicable Parts Inside" warning.

The cabinet is held together with more philips head screws than I think were truly necessary. The real trick was discovering the two screws hidden inside the rubber feet, and the hex-head screw.

Luckily (Luck favors the man with too many tools) I had tools to remove the recessed screws and the hex head (metric, of course) screws.

Once I reached the Inner Sanctum, where no man has ventured since this machine left the factory, I discovered that the problem was the stupidest of all reasons.

The air-fryer has a push-button switch on the door so it can turn off the power to the heater element while the door is open.

Turning off the power does not cool the pans and grill. Trust me, I've tested this.

After introducing the switch to tuner cleaner, more percussive maintenance, and pointed profanities, I decided that the switch is a stupid design decision and I can make the air-fryer work by cutting the wires that feed in and out of the switch and joining them together to bypass the non-functional switch.

Now, if the air-fryer is on, it's heating, regardless of whether or not the door is open.

I maintain that I didn't do a hack-job of a repair, I simplified the state diagram defining the air-fryer's behavior. Simplification is a classic re-engineering technique.
