I have read a couple entries here, and currently have a paper-clip bypassing this switch to get my furnace to work. Very cold here in Illinois! I also know that either the switch is defunct or the main vent is blocked at some point. I would like to get a new switch which I read runs about $20 but I can't find anyone locally to sell me one. Everyone is trying to get me to let them come over and repair it. After being fleeced too many times, I am trying to find this part. Any ideas would be greatly appreciated! Last guy told me only contractors can buy this and didn't even know what it was,...
