Furnace help

Well I finally pulled the furnace from the Travel craft and cominced to trouble shoot my heater problem.My hunch was a bad fan switch so i started with a continuity test through the fan circuit the two disk switches I pulled and read with a meter while using a lightbulb as a heat source opens and closed as they should however the fan switch was a bit sloppy at first.the sail switch was found to be good as well. The fan motor spins free so I went back to the trusty print and read the circuit through the thermostat switch and found that the coil wire that pulls in the fan circuit had burnt into right at the spot where it leves the coil.So good news is I found the problem. Bad news, part is no longer available,but thank goodness there's eBay.I found it there and bought two of them. As soon as they get here I'll get it up and running;that is if the ignighter board hasn't got a fault. Thanks again for all the info given me on this essue.
