Answer John, First thing, remove power to the cooktop and turn the gas supply off at the wall. Remove the vent cover grille, burner knobs, and vent motor knob. Remove the two phillips head screws that attache the escutchean to the cooktop, on the inside of the blower plenum. Lift the escutcheon up in the back slightly and slide the assembly away from the front, until the locking tabs are free and you can then lift the escutcheon up and off the housing. Now you should have access to the switches, remember to change them one at a time, so you don't mix things up. labelling them can be helpful as well. Reverse the procedure, restore power and gas and check the burners for operation. Read More... Answered by AppliancePartsPros.com | Monday, December 10, 2012
