One of my burners doesn't spark so I'm thinking I need a new spark switch (under the knob). The burner gets a spark and ignites when I use a different control so I thought the ignitor was OK. I also thought the module was Ok since three of the burners work great. The cooktop is laid into a opening in a grantite top. I just looked under the cooktop and all I see are sheet metal panels with the bottom sides of a lot of sheet metal screws. How in the world do I dis-assemble the cooktop to replace the switches when nothing that can be unscrewed from that end. I believe the switch part number is AP3185909. If you think changing the switch(s) isn't the correct diagnosis, I certainly welcome any and all advice you may have!
ANSWER Bob, The hardest part of the repair, is removing the cooktop from the counter if needed(some models). In your case you may want to, unplug the power cord or turn power off to the unit. Remove the burner knobs, grates and burner caps. Remove the two(2) screws holding the burner base to the orifice holder under the glass cooktop,on each burner. Remove the burner base, and label the wires that attach to the igniter. Slowly and carefully lift the glass panel off the burner box base. The igniter switch harness comes as an assembly WB18T10339 and has all four(4) switches and wires. Thanks and Good Luck
