My thought was the fan wasn’t pushing enough air to keep the sail against the switch when installed. Held my hand over the hole where the sail goes and the fan is pushing air a good 2 inches from the motor. So I would think that’s enough to close the sail against the switch. I finally gave up and have a tech coming out to check it out. I will post the results when it is fixed.

I've learned that just about anything is possible. It's possible that there's something wrong with your fan so that there is reduced air flow. However, I'd be more inclined to look again at the sail switch. Does the new one look exactly like the old one? Does the old one work when pressed in your hand? I've seen new sail switches just not work very well. Did you buy an OEM or aftermarket switch? Did it have good ratings? Sometimes they can work when vertical but not horizontal. Sometimes the sail just needs a little tweak to better catch the air.
