I had the same problem. Mine was caused by liquid seeping into the infinite switch (the switch that gets rotated by the knob to set burner temperature). This caused one of the live wires to short to ground within the switch. Bad Design IMHO. Replacing the switch fixed the problem (you can get replacement parts at Searspartsdirect.com - search using the cooktop model number).
You first need to remove the unit from its installation. Start by disconnecting the exhaust fan from the ductwork. Then push the cooktop up.
To get at the switch you need to remove the top by taking off only the top row of screws all around the unit and also in the down draft cavity (the down draft cavity is where the grease guard mesh is)

1) turn off power at the breaker. 2) remove hold down screws 3) pop up cooktop out of counter top 4) remove knobs and downdraft grille 5) remove ceramic top (screws around outside and also in side grille opening) 6) unplug burners replace with new burner

Turn off the circuit breaker to the cooktop. Verify by making sure the burners/fan do not come on. Disconnect the exhaust fan (underneath the cooktop) from the ductwork by removing the tape that joins it. While you are underneath the cooktop, open the junction box. Label the four wires that are joined so that you will be able to connect them later. Then disconnect the four wires. Remove the metal sheating that connects to the junction box (there is a nut on the inside of the junction box that you loosen. Pull out all the supply wires (from the mains) from the junction box. Then push the cooktop up and out and lay it flat on a table with the flat side down.
Take off only the top row of screws all around the unit. Rotate the unit so that you can get to the down draft cavity (the down draft cavity is where the grease guard mesh is). Remove the two center screws. Then pull the black top off.

Use Cooktop Cleaner with a soft micro cloth. Don't use water. Buff until the mark disappears. Hint: Never clean the cooktop until it is completely cool to touch as doing so makes cleaning much harder. Never use abrasives on the glass or abrasive cast iron skillets.

I just had the same problem- when I replaced the whole cartridge.
I repalced the infinite switch- do the one that gets the hottest- or do both.
It is easy to do- just write down the wiring diagram - make sure all power is off- cost of new switch was about $37.00
This solved the problem- however make sure to check the sizng on the new switch shaft as my old knob would not fit properly on the shaft of the new switch.
good luck

you may have lost a leg of your 240V service. make sure you have 240 to the appliance and then start chasing down where you lost it. there is no onboard trip or reset on this unit

is this down draft cook top or give me the m# thanks
