Door needs assistance to open all the way - Chamberlain Liftmaster

Have a Chamberlain Liftmaster. When the remote button is pushed, the door will go up about one foot then stop. Sometimes it will go all the way up on the second try. Some times it takes several tries. Sometimes it won't o up at all unless I help lift it up.

Watch the door go up and down to figure out the problem, but it sounds like a problem with the springs. We have had similar problems with our garage and it is usually because one spring has more tension on it than the other so when it tries to go up one spring pulls more than the other and the door gets wedged on the rails. I have found this usually occurs when the springs get older and they usually break a short time later. The best solution I have is to check and possible replace the springs.

Check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flashing. Tweak them a bit. If you cannot get both lights to come on you have a bad sensor.
