SOURCE: garage door opens a few inches and stops

On the rear of the motor unit near where all those white wires go you will find the 'up force'. Increase this 1/4 turn and try.

SOURCE: my garage door opener (liftmaster 1265) buzzes

Remove the cover from the motor unit and check the drive gear. It is white nylon and is just in front of the motor. Most likely stripped.

You don't say but I am going to assume the door is stuck in the open position. Loosen the chain enough to relieve the tension on the trolley. Now run the opener until the door closes. While the door is closed locate the 'up limit' control on the side of the motor unit. Turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Tighten the chain.

If the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. Make sure the lights on the sensors are both on and not flickering. Tweak them if necessary. If you cannot get both lights to come on you have bad sensors or the wiring to them.

Garage door opener chain out of sync with door


There are two white screws on the sides that adjust the limits. Adjust the "down" screw less. You should have to turn the screw 4 full turns for eight inches. After you make this adjustment, test it without the door being hooked up to prevent damage to the door or opener if it tries to close too far.
