What does the asterik with the tear drop on the middle control mean on DeLonghi AR690 Retro Toaster Oven?

Possibly an internal fuse opened.

instruction manual did you throw it out in the garbage ?

follow this steps and fix it. God bless you

f the oven doesn't work at all, make sure the circuit breaker or fuse is on at the electrical service panel and test the electrical cord . If the oven doesn't work on its toaster and oven functions, test the main switch . As needed, check the fuse .
If the toaster function doesn't turn off unless the door is open, test the solenoid, the switch and if necessary, the thermostast.

Location of the typical toaster oven's thermal fuse.
If the toaster oven stays on when the door is opened, check the main switch . If the oven doesn't heat, test the heating elements.

The manual mentions nothing about any user serviceable fuse or reset. "Funky" wiring in your home shouldn't cause an appliance to fail. Wiring that is in poor condition usually results in blown fuses or tripped circuit breakers in the service panel, heat in places it shouldn't happen and of course, fires.

It is very possible that the outlet is worn to the point that it doesn't make very good contact with the toaster's plug and has caused the toaster to fail to heat up. Try removing the toaster to a different outlet and try again. Check the original outlet with another appliance or lamp, etc. to see if it works or not. Also, check to be sure any ground fault outlet hasn't tripped.

If the toaster fails to work as expected in another outlet, there's little you can do to repair without jeopardizing your safety - especially if you're not familiar with appliance repair. These appliances aren't really meant for disassembly - manufacturers don't want to be liable for "repairs" that end with injuries, burns and death so the make them pretty hard to take apart. Even if you are successful, they make even harder to reassemble without it looking obvious that it has been disassembled.

Take it apart if you want - learn about how it works and buy a new one. These devices don't rely on rocket science and the controls are pretty simple - but it is an electrical device and electricity isn't a hobby. Be safe. Be smart.

BTW - I don't want your money - I just don't want you to get hurt.

Goiod luck!

your heating element has gone bad or there is some bad wiring in the oven itself

to check open up the toaster oven and look at the wires coming from the heating elements inside to the timer on the front panel if there is no bad wiring then the heating elements are bad and the toaster oven needs to be replaced

This is a two slice Delonghi toaster, model CT12 and is has stopped heating on the right side

Test and eventually replace the temperature probe. When the problem is not the temperature probe it is a faulty timer board.
