Good Morning, RAlan:

I assume that the only time the heating element works is when you put it on the bake cycle. This means that you are not able to program the unit to run with the digital clock
to "Set And Forget" the unit.

Obviously, the clock has a switching circuit that activates at a predetermined time. I would, therefore, encourage you to check this switching circuit for a failure.

Since the unit has a one year warranty, is there any chance you can get the manufacturer involved in this repair? The list price of the unit is about $130 and would expect Black and Decker to support this piece of equipment.
