Dometic Furnace Sail Switch Issue

Looked through ebay .

33082
Looks to me there is a big difference in appearance of the arm. Large paddle would close the limit switch with lower fan speed.
What is wrong with your furnace?

Intermittent operation. Sail switch fixed it. Now problem is back. Ordered both numbers sail switches. Seems Dometic had an issue with this part. Bracket was a problem not letting the arm close enough. But the correct part number is up for debate! 36160 is hard to find. Found one on eBay.

Did you check for loose connectors on sail switch circuit?
What part of Washington?

Checking circuit is next. Sail switch seemed initially to be the answer. Lots of on-=line issues with it. Now in Idaho

most of the time the sail switch is improperly diagnosed but people don't want to tell you they changed it for nothing. The first thing to do is to check to see if there is voltage through the sail switch when you start your ignition sequence. If you look up the electrical schematics, you will see there should be a line that goes through the limit switch and sail switch before getting to the board. If you have power at the board then it isn't either one of these. If you don't then it could be either or and you must test in between them to see which one it is. It's easy to find the wiring diagrams for the furnaces online and they will show you how yours is configured, sometimes they may have a circuit breaker in line also but mine doesn't.
