JVB98H1SS General Electric Range Hood

I pulled up the wires that the membrane switch hooks to and connected the new one with the new sensor pushed them down the opening. Took the sticky paper off the up and down button and stuck it too the indentation where it goes and there you have it as good as new! Works great!

Disconnected power and removed electrical cover
Disconnected wires from old controller one a time and connected to new controller as to not mismatch wire connections. Left new controller hanging off wires.
Raised vent and held using wood blocks to expose gap to use 1/4 inch wrench to undo screws from the inside (poor design for replacing the controller - this was the bulk of my time.) if this didn't work, I would have had to disassemble more of the downdraft.
Installed new controller.
Removed chocks, enabled power and tested...after verified, re-installed electrical cover.

Received membrane switch quick after I ordered it. Connected switch to downdrafts system in less than 15 minutes. Tested system to make sure it worked. very happy with partsselect shipped quickly after ordering.
