I've read in forums to fix a leaking (from bottom) furnace, "remove small panel around the copper pipe and check the evaporator coil for a clog." I think I’m trying to open the right panel. My furnace stands vertical, I’m reaching up to a copper wire and padded wire (I think also copper)...

Hello, everyone. I have this power vent kit on my gas furnace: http://www.fieldcontrols.com/pdfs/46285100.PDF Actually, the vent itself is different, but the control box is the same. Sometimes my thermostat turns on the furnace, but the control box won't turn on the blower. I had a...
