The LiftMaster 8500 opener model is often used on a 10*12 garage door. At times users experience a difficulty in getting the door to move in the downwards direction. They need to lift the door when it is in its last one and a half foots descent to get their camper through. An imbalance of the spring with the garage door is often the cause of this as it is essential that the springs geometry is aligned properly for ease in opening and shutting the door.

Let us go through the probable causes of this problem and their solutions:

  • A misalignment in the garage door or the springs or tripping of a garage door sensor can lead to the problem in shutting. There is no need to make any modification if your garage door is of the right size for the opening.
  • There is a flapper attached on the wall through which a LiftMaster model 8500 garage door goes through. When this flapper opens, it can reverse your garage door. The flappers on other LiftMaster models dont function in this manner. So, you need to get the door adjusted correctly to avoid this unusual flapper motion. One way of avoiding it is to pull the door just as you hit the button.
  • Is the shaft turning and unwinding the cable of your garage door? This can explain the problem of the door not completing its descent when shutting. Does the wireless light on your garage door blink when you close the door? This can be due to an imbalance in the spring or due to binding of the door when it reached its topmost height. You can solve this problem by leaving its spring a little on the heavy side when you balance it. By doing this you will allow for the gravity that the garage door needs for coming down, however, make sure this happens slowly allowing you time to get out the way. Moreover, make sure the garage door does not bind when it is at its top.

In a LiftMaster 8500 opener model, the door needs to sort of hang on the cables a little for the opener to function smoothly. This is different from traditional garage door openers in which an opener is attached to the door to pull it down. Use the cable tension monitor that comes with LiftMaster garage door openers to ensure that it is of the right tension. You can get in touch with us at any time of the day to hire our technicians for this job.
