What are the dimensions - I can't find the answer anywhere

That number looks like a serial number as opposed to a model number. Black and Decker start with 'TO' for Toaster Oven.

Greetings from Toronto!

Try a warranty claim on their 2 year warranty. Free repair is good eh?

Seems to be the last one on the net!

Hope this helped!

you have a relay failure . its real common on all digital ovens in general after looking up yours , there are no inside parts made for this oven . this is another problem with all "made in china " appliances THERES JUST NO PARTS! anywhere ! see what your warranty will do , if thats no good, some krups appliances can be sent back for "repair " its not realy repaired just replaced at a reduced cost . i wish you luck .........Please if this answer helped , please rate this 3 or 4 stars . and keep me in the paid answer department . A 1 or 2 may knock me down into the unpaid ranks. Thanks Cactus Bob .

I have same problem.
Found 1 parts distributor who has the part supposedly in stock, but shipping was pretty expensive so I'm waiting:

Cost was $10.66 but shipping is even more than the part! At least you can get one if you need/want!
