Garage Door Opener Stops or Reverses When Activated

My garage door opener doesn't close all the time. Well, sometimes it does... then sometimes it reverses at the bottom, sometimes it reverses right after it starts moving. What's a mother to do?

The first thing to check are the electric eyes that are located on either side of the door frame. Their purpose is to detect an object in the way of the door and reverse or disable the opener. If the eyes are not facing directly at each other, they may work intermittently, causing occasional spontaneous reversals with no rhyme or reason. If you don't have these eyes, no one stole them... you just have an opener that was built before the 90's when they became mandatory for all newly manufactured openers.

To check the function of the door...

Disconnect the garage door opener from the door and go through the troubleshooting routine on the garage door repair page.  In fact, you really should read the entire garage door repair article.  It will make troubleshooting later much easier!

Remember that sometimes, a garage door opener can increase the binding in a door just because of the way it pushes the door down. Ever notice how it is easier to pull a wagon over a curb than it is to push it? Same principle. Garage doors were designed to be pulled, not pushed. You may think the door is working OK because it feels OK, but you should still check all components to be sure.

Do any necessary repairs, reconnect the opener and try it out. If you still are having problems, you can make slight adjustments to either the closing force, opening force, or the travel limit adjustments.

Some older garage door openers do not have nicely labeled adjustment screws for force and travel limits. In fact, even some of the newer openers manufactured for and resold by your basic garage door company are not user friendly. This guarantees return business... costly minimum charges for diddly adjustments! Unfortunately, I cannot give you specs on every opener and all the configurations, but, if you want to know how I have approached the problem of limit adjustments on an unknown opener, it's really a matter of observation and educated guesses.

CAUTION : This is true, seat-of-the-pants troubleshooting. Because of the power of the motor,
there is always the risk of injury, so you must be very cautious !
If you feel uncomfortable continuing, call a professional!!
