Automatic Garage Door will not open more than 3 feet anymore.
Out of the blue the garage door opener will not open the door more than 3 feet without stopping, sometimes it is not even that high. I disconnected the door from the opener by pulling the release cord and it still stops at the same 3 ft or less. I turned the adjuster to make the door go up higher and it didn't make a difference. I also increased the up force with no difference.
Any ideas on what is causing the issue? I won't work even if there is no load on it.
It is a Lift-master ats211r.

I did of that, it still doesn't go up more than 3 feet and a lot of times it is only a few inches. Sometimes it will stay there, others it will close after it reaches a few inches.

if you cant lift the door full open manually doesnt sound like an OP issue. is the door heavy? is it balanced?

It seems to be riding on the track ok when I disconnect it from the opener, the springs are intact, the track looks good.
It is a 16' door that is 10' tall so it has some weight behind it, but not excessive.
The opener does this even when the door is not connected to the opener and the trolly is just moving back and forth without a load.

Just a guess....but it sounds like a problem with the interrupter assy. This is a little plastic wheel with notches in it that interrupts the path between an LED and sensor. It basically tells the logic board that the motor is running. I've heard that dust and cobwebs can cause an issue, also that the wheel can loosen.

possible, but i wouldnt think this on a commercial type OP like this one.
if the OP wont cycle and is travelling more than 12", something is telling the OP to stop. the board or something has made drastic changes to the limits. the case needs to be removed and id check the limits.

Darren...the only reason I said the interrupter is because of how the travel changes so much. In my experience boards normally fail and do the same thing all the time. Not GDOs...just electronics in general. Is it possible the gears are worn and slipping?
Regardless...I agree..the case needs to come off and see what's going on in there. A bunch of snow would be a good indicator...lol.

I pulled to back off today and everything seemed to look in order. I will have to look closer at the interrupter.
