Question about Chamberlain Building Materials
We have made sure the pulleys are the same distance from the wall - - nothing is obstructing the door - - the door goes up just a little bit then stops - - will go all the way down - - manually the door works fine

Okay...upon further inspection, my left spring has broken in two. Going to call around for some quotes to replace the spring. Thanks for the suggestions.

The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.

Well sounds like its a pressure setting. you said you open the door by hand? Was it easy to do? Ask your self this can a 15 year old kid open it and close it? If so then it sounds like its a presure setting There should be two blue slots on your opener with numbers 1-9 says up and down force. Turn the up force towards the bigger number. Just a little bit. But before you do that as the other guy stated make sure that your cables and springs are working. Spring depending on your doors can be in three places but we going to assume you has the most common set up so look over the top of your door (with it closed) you should eb able to see a tube running across there. and somewhere in the in middle a set of spring look at the spring to make sure that you dont see any of the tube showing in the springs. Becare not to touch the spring as they are under a lot of stress.

On the back of the motor unit you will find the down force control. You may have to remove a light lens depending on your model. Increase this a 1/4 turn and try.
