Shorted Switch from a pot boiling over
Lift the cooktop out of it's inset in the counter top, flip it upside down and lay it on towels to protect the cooking surface. There is a raised rectangular panel that covers the switches located about the center front of the bottom. Remove this panel with a small nut driver to expose the switches. Now, locate the dead switch and place a strip of masking tape pointing to it and lapping around the edge so it can be seen when the unit is flipped back upright. Flip cook top back upright. Locate the correct switch by observing the masking tape. There are two small, short-threaded, phillips screws holding the switch in place. They must be accessed from the knob hole (remove rubber grommet)and at a slight angle. There is very little room to extract the screws...this is where I used the magnet to magnitize the tip of a small screw driver. Once the screw is free of the threaded hole, lift it with the magnetized screwdriver out through the knob hole. The switch will fall out easily when the two screws are removed. If you drop one of the screws inside the stove top, don't panic, I was able to shake the cook top and retrieve the screw. Now, flip the top back upside down. Using a pair of pliers remove each wire one at a time from the bad switch and connect it to the same terminal on the new switch...this way there can be no mistakes. Be sure the rubber insulator removed from the bad switch and placed on the new one. Position it where the screw holes show through, then place the switch in position. Turn the top back over in the upright position but position it where you can reach underneath it with your left hand. You will have to hold the switch and maybe move it around slightly to aline the screw holes when replacing the screws. Take a screw on the end of the magnetized screwdriver and carefully insert it into the knob hole and into the switch bracket. once you get one started, the other will be easy. I don't recall the screw replacement being any problem, just that you have to handle the screws carefully, so as to not drop one inside the cook top. Now, flip the top back over and replace the cover over the switches and replace the top in it's cabinet. The job is complete, Oh, and don't forget to flip the stove's cirduit breaker BEFORE even touching the stove!

Looking down at stove top the upper left large burner seems to only work on high settings and then you must turn off to make it cool down, is this the upper control thermostat on right of top that is bad? I see a couple of parts listed but not sure. Thanks
For model number g7ce3034xb

Looking at the top of the cooktop, the top right burner switch, the post that holds the knob has broken off at the base of the switch. Am I able to replace the post or should I just replace the switch and which switch do I need?
For model number MEC7630WS00

Hi Ron, thank you for your question! The post of the switch is not sold separately, you may need to replace the entire infinite switch, part number PS2377004. We hope this solves your problem!
