The oven no longer heats up when I set it on 'bake'

Worked fine yesterday. I wiped done the control panel, and afterwards it wouldn't start.
I thought perhaps I messed up the setting when I wiped it down- but it seems that the top element still works.  

I'll call customer service and see if they can help. but you guys know everything under the sun, so i expect you'd have an answer before CS answers the phone.

I think you can Ohm it out with a meter to test. Not for sure of the numbers your looking for though.

I've had the potentiometer,( heat control, off/on/volume knob), go bad before. Should be able to get one online.  Simple to replace.

BTW, your username is ironic

Ohmmeter. Check the element, first terminal to terminal, then terminal to the outside cladding on the element. 1.5 to 7 ohms is a normal range from terminal to terminal, you should have no conduction at all between the terminals and the cladding. If the element reads good, you may have a bad relay or controller if it's a newer oven, or your membrane may have failed if it has membrane switches on the front. You failed to note a make or model number, so I can't tell if it's an older switch type or a newer digital.

OK- found a break in the element that I didn't see before...

-with an odd white colored powdery substance on the 'floor' of the oven...

Alumina powder and magnesium oxide, just wipe it out.
