XRS Airlift Doors - Stopping halfway down

[WashSingh]

I have a pair of XRS Airlift Doors that I installed in my bay roughly two years ago. I've noticed recently that when a car enters/exits the bay, the doors sometimes stop about halfway on their way down. This usually leaves about a 3/4 foot open gap between the ground and the door. As the weather is starting to turn, I'm concerned about the doors not closing correctly in the winter time. Has anyone encountered this before?

WashSingh, Which track to you have? I have had the poly track get a little missed aligned when the temp changes which could hold door up.

Edit. Sorry This applies to Poly doors not XRS

You need to adjust the cams on the motor assembly. Instructions are in the manual

Garbageman is correct the cams need adjustment if you don't know how to do it I suggest getting a door company to do it as you can really mess up the door if you adjust them wrong.

The cam's . Is this limit switches or something different?

 

[garbageman]

yes, they are the limits. they are adjustable with an allen wrench (metric). If the door is that far off it may have missed the upper limit once and rolled over on itself. Usually the cams only need to be adjusted a few inches after initial start up

Yes ok . However I have seen this an cycle the door up then down an then it runs normal on a line up day ?
