Craftsman Garage door opener - not opening/closing. Also LED blinking 11 times

I have a Craftsman Garage door opener. Today suddently it started malfunctioning wherein when i try to open it, doors lifts up little bit (say one feet) and then it stops. As part of initial troubleshooting here are my observations:

- Door stays in same place whenever i press the button. I would expect it to open on first press and close on next press. Instead it opens for one feet. Next press, it again closes and then opens upto same location
- If i disengage the door, i see the belt rotates only upto certain level and then it stops (same distance when the door was engaged)
- The obstruction sensor shows green light and i see that if i block the path between two ends, the green light goes off. That makes me thing the safety sensor seems to be working fine
- I opened the side where bulb goes and some wires are connected, and i see a LED blinking exactly 11 times and then stops for few seconds and repeats. I checked multiple times and it is 11 blnks and not 10 as comes up in google when i search for blinking related to garage door

Any suggestions?

Welcome to the forums.

It's helpful to have a model number to go along with the problem.
That tells us the manufacturer too.
