All of a sudden our garage door stopped working and the light flashes 10 times. Liftmaster Model 2265 1/2HP. Any ideas?


We just had the same problem this morning (cold weather can mess these things up). Not sure what you mean by "not working". Ours would open part-way and then stop (or close part-way and then stop), but could open/close all the way if we held the button on the wall down the entire time it was lifting. After much research online, we ended up checking the sensors at the bottom of the garage door tracks to make sure that the green light was solid (not flashing). Ours flashed a bit, so we cleaned the "eye" and tightened it in place. Once the green was solid, we thought we were done, but still had the problem.

Then we began adjusting the screws on the unit itself that show pictures of the door opening and closing. We thought we were adjusting the torque in the unit (because we read online that cold weather can make it more difficult for the motor to work), but in reality we were adjusting the opening and closing "distance". Apparently cold weather can also do something to the tracks, which can require adjustments to be made. Something to do with ground swelling...

Anyway, we also discovered that when we had closed the door manually (red pull-cord) the night before for lack of a better solution, it never properly locked back into position, which was adding to the problem.

So, first, try cleaning the sensors. You need a solid green light for them to function properly. Second, if you have used the manual cord, make sure the arm that it attaches to is locked back into position. You can accomplish this by pulling the manual cord, manually closing the garage, and then pushing the button on the wall. The door arm should lock into place. Third, try using a screwdriver to adjust the open/close distance. Start with a 1/4 turn for each position, and play with it until you find the right setting.

If these suggestions don't address your problem, this link worked for us...http://forum.doityourself.com/doors-windows/368278-garage-door-wont-go-down-cold-weather.html

Lift-Master garage door opener stopped working


The motor will probably need rewinding.
Professional job. Don't forget to take the condensor with the motor.
Or alternatively, if money isn't a problem,, get somebody out to look at it.
There ya go:)

Liftmaster pro 1/2 hp wont shut in one button press


You have a door sensor problem. Either your main light bulb is burned out or you don't have one in your opener. The clicking sound you hear is the relay for the light. Both of the door sensors should have a small light that is lit. Tweak them until they are.

I have a 1995 Sear garage door opener that stopped working


The trolley (the part that moves back and forth and is connected to your door) of your opener is most likely jammed against the bolt just in front of the motor unit. You can remove the bolt or loosen the chain until your unit will run. Once the door is closed find the 'up limit' on the side of the motor unit and turn it about 3 turns in the opposite direction of the arrow printed on the cover. Now replace the bolt or tighten the chain. Whichever you first did.

Opener wont open makes clicking noise


Your opener has been hit by lightning or power surge.
If it's not too old you can replace the 'back board' (the computer board on the back of the opener.) Also If the opener has safety sensors one or both of them may be burnt out too, and if it was really bad then the rpm sensor will go too. So you could be looking at paying half the cost to repair or just get a new opener. Up to you, and get a surge protector. Lift master has a good line of products and makes thier own surge protectors for thier products.
