Furnace sail switch not working
I have a 96 thor residency 36' motorhome that has been sitting for a few years. Has front and rear furnaces, ignition style atwoods. Upon starting, both furnaces fan's run strong, but wouldn't light. I bypassed the sail switch and both furnaces operate properly. I removed a sail switch and tested it for continuity, and it works! My fans seem to be blowing strong out of all floor vents... Do these switches get stiff or stuck when old???
One other question: I can find a power transfer switch, or converter, if anyone knows where they may be hidden. Thanks, Ken
