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.

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 have a neighbor that can open my garage door with their remote. Can I change my code to open the garage door


Yes.
How to do it depends on make and model.
Get that information from the Garage door opener (this should be on a sticker on the outside of the unit; most likely on top so you'll need a ladder) and you can go on line to the manufacturer site and find the information on resetting the codes.
You will reset it on the Opener first; then you have to "retrain" your remotes and keypad to work with that new code. If this unit has been in place for a few years, it's a good time to replace your remote batteries also.

Previpus owner didnt supply 4 digit cide to sears garage door opener keypad


Simply call a local garage door service center and take your keypad into them and they will be happy to show you how you can do it. It usually involves having to push a button up on the back of the garage door closing unit so the device can pick up what is a "rolling code" instruction and the unit will work just fine for you. Just remove it and be sure to know the model number of the opener too before you go.

Many of these devices use a code that changes each time the door is opened and closed. This feature is used to keep potential bad people from learning your operational code and entering your garage. You may have a communication problem whereby the Garage Opener needs to be reset. You may try to change the settings. If you have dip switches on the main unit in the garage, change the dip switches to another setting and write down the numbers in the order that you have the set them, Then go to the remotes, hand held and hardware placed on the outside door, and change the settings on these devices to MATCH up with the inside unit. This is a good time to REPLACE the batteries also.

Outdoor keypad frequently doesnt work


IF REPLACING THE BATTERY DOESN'T DO IT YOU WILL NEED TO REPLACE THE KEYPAD.

NOTE: (IF YOU HAVE A ROLLING CODE SYSTEM) YOU WILL NEED TO REPROGRAM THE UNIT AFTER YOU CHANGE THE BATTERY.

HOPE THIS IS HELPFULL

First of all, did you try recoding unit by hitting LEARN BUTTON on motor. Try that. If n/g, try a new code with a number you did not use. Example, if old code was 5834, try 2222. If it works, one of the numer from you old code is worn out. Try new code or buy new pad.
