No, there is no fuse. There is a safety thermostat that detects when the toaster gets too hot and will shut it off. However, it is very unlikely that this has gone bad.

Most likely, there is a problem in the mechanical linkage that turns on an internal switch when the toaster bar is pushed down.

The other possibility, which is far less likely, is that the power cord has a break in it. Sometimes, if the toaster is moved around frequently, the power cord gets flexed too much and then breaks where the cord enters the power plug. Fixing this involves replacing the power plug. To diagnose this, you can carefully hold the power cord in slightly different positions and see if the toaster powers up in any position.

Do not try to just pull it off, you will likely damage difficult to repair parts.

On the underside remove 6 pozidrive screws 3 each end (one under the crumb tray)
Standing on its base - open the doors and remove 4x countersunk torx T10 screws, near the top, that screw from the inside into the end covers.
Now remove the opposite end to the knob, (in order to learn how it is held). Pull the bottom away from the base to the left, around 5 mm, and slide the whole end cover upwards, it unclips at the top. The other end is not so easy of course because of the knob. Release the cover, as before. It is possible - with the knob at the top, pull the bottom of the cover out 5mm and push hard to slide it upwards as before. The cover will release from its top mount. Then slide the cover all the way up, as far as the knob slot will allow. This will allow you see and have access to the back of the knob and the plastic clip that holds it in place. Stand the toaster on its base, with the end cover lifted up it is easy to put your hand inside the cover from the top and putting your thumb and forefinger around the bar you can grip the plastic hook and ease it downwards whilst you use your other hand to pull the knob and its firmly attached bar away. It will be necessary to wiggle the knob up and down whilst pulling it outwards. The bar surface is not flat, it has ridges that hold it in place quite well, even without the clip, hence the need to work it up and down. That's all there is to it! Hopefully you haven't broken the clip off, but if you have, don't worry you will still be able to use the toaster with little impact. The attached photo shows a close up of the knob and bar just separated from the mechanism. This should give an idea of what you are up against.
What a fantastically well made machine this is, a real pleasure to work on.

I was able to replace parts on the circuit board (P/N: 128301_timer_pcb) to fix this issue on my KCO253CU Kitchenaid Toaster Oven. R1 was visibly burned. On further troubleshooting, ZD2 was found to be shorted.
Known Failed Parts Replaced:
R1: 47 Ohm 2 Watt resistor
ZD2: 47V Zener Diode
Other Parts Replaced
C1: 1.5 uF 400 Volt Film Capacitor
ZD1: 5.1 V Zener Diode, tested OK but replaced anyway.
See attached photo of circuit board for component part numbers.

Hi, W/D here.

Easy fix. Your upper locking bar has slipped. While someone is holding the door handle in the open position, you'll need to push the upper lock bolt back far enough to get the door open. You can slide it back carefully with a screwdriver or knife, a little at a time, while holding slight tension on the door with the handle. OK, door's open. Remove the inner door lock cover plate. The lever and locking knob will come off with it. Remove the mortise cover plate, on the edge of the door. Insert a small, thin bladed into the upper alignment slot in the lock behind the mortise cover plate, and loosen the upper allen screw behind the inside lock cover plate. Use the screwdriver to engage a slot in the locking bar, and raise or lower the bar until you have it level with the alignment slot. Tighten the allen screw.
Sometimes, the bar is so far out of alignment that you will have to gain access to the other end of the bar, in order to raise or lower it. This is done by removing the plastic cover on top of the door, and using needle nosed pliers to move the bar.
This should fix you up.

Best regards, --W/D--

Thanks.

I had the same problem with a "Sony VPL-ES3" projector. The lamp cover light would flash and the projector wouldn't turn on.
I think its a problem with a filter cover. This fixed the problem for me: 

1. Plug out the projector
2. Click off the filter at the bottom of the projector.
3. Plug the projector back in. (the lamp cover light should flash)
4. Plug the projector out again.
5. Put the filter cover back on.
6. Plug the projector in again and it should work fine.

This has worked for me every time I have had this problem. 

see http://www.fixya.com/support/t153483-no_oven_but_still_toasts. the suggestion for thsi problem helped us withthe problem that you describe. Clean the contact after opening fromthe right side.

Never buy black & decker they don't supply parts they want you to rebuy the same junk over & over. its a shame this is what american companies have become buy japanese they last longer and make replacement parts.(I'm not unpatriotic just an informed consumer).

I doubt if you can fix this without taking the unit apart. Usually it is not that difficult to remove the cover. Unplug the unit. Turn the toaster upside down and remove the screws holding the outside case on. The case usually slides off or by springing the bottom of the sides out you should be able to remove it. Once the cover is off it should be easy and obvious to fix the problem you described. When you have the unit secured reverse the order to assemble the unit and you should be back in business. Good luck.
