How to Troubleshoot & Replace Ge AP4411806 / WB24X10174 Switch Fan

Had to remove the glass top to get to the switch. Removed the burners and Igniter's to get top off. You can NOT go through the bottom to remove this switch you have to remove the glass top. 

This part worked great to swap out the fan switch. Getting access to the switch was an ordeal. I watched several available youtube videos for other GE cooktops which showed how to lift up the cooktop and access the swtichbox; however the downdraft version requires additional steps to access the switches, and I could not find a video. I was able to drop the wire housing box by removing four mounting screws from below. This lowered the wire housing box approximately 4-5 inches as it was limited by the wires. I was then able to push the broken switch down out of its slot, and swap out the broken switch via that 4-5 inch gap from the side and under the counter. Cleaned all cooktop parts, reassembled the switchbox, installed new Clear Tape, and new Foam Tape, and dropped back into the counter. Tested all the functionality and celebrated the successful repair! 

This was more difficult than expected. I ended up calling a pro and it took the two of us to hold the cooktop and move it around. I had to remove the cooktop and tilt it to reach the screws that held the plate that held the knob in place. I don't know who designed this thing, but they did not take into account servicing it. If I had to do it again, I would also order the gasket that goes around the edge of the cooktop. We managed to salvage it, but I would have liked to replace it. 

Watched a youtube video on how to remove the glass top and then it was straight forward to remove the damaged switch and replace with the new one. Project took about 2 hours.
