SOURCE: Lift-Master garage door opener Model 1045-6 1/3 hp

There is a thermal cut out in the motor, usually the motor must cool before the opener will operate again. If the opener only operates 3 times it must be heating up too quickly.
First you opener is only made to do your job for you, which is opening and closing the door. If the door does not operate properly manually the opener will not operate properly.
When the door is disconnected from the opener it should lift easilly, it should basically stay at whatever point you let go of it (midway and fully open) and it should close without slamming down. It does not matter what size the door is!!! If it does not something is wrong with your springs and the door can be VERY DANGEROUS!!
With that being said it sounds more like a static lock-up possibly a loose ground or even a circuit problem in the home.

It's on the rear of the motor unit. Just below where all those white wires go. You will have to remove the light lens first.

SOURCE: Chamberlain Lift Master Pro Formula 1 only makes click sound

Is the door stuck in the open position? If so the trolley is probably jammed against the bolt just in front of the motor unit. Loosen the chain enough to free the trolley and then run the opener until the door is closed. While the door is closed locate the 'up limit' on the side of the motor unit and turn this control 2 complete turns in the opposite direction of the arrow printed on the cover. Tighten the chain.

I am trying to reprogram the keyless entry for the garage. The garage door is a Lift-Master model 1280


If you know the existing pin you do this:

  1. Press the four buttons for the present PIN, then press and hold the # button. The opener light will blink twice. Release the # button.



  1. Press the new 4-digit PIN you have chosen, then press ENTER. The motor unit lights will blink once when the PIN has been learned.


Test by pressing the new PIN then press ENTER. The door should move.


Otherwise you do this:



Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.
