Garage Door Openers Can Think
Garage doors have two main sorts of springs. Extension springs run along the horizontal tracks on either side of your garage. They obtain their power by extending. Torsion springs run along a bar you can observe above your garage door when it is closed. Torsion springs obtain their strength from twisting.
In most cases if one of your springs is busted it can be completely impossible to open your garage door. The exception is if you have a single door and it is made of a light metal. In any case it is best not to attempt to open your door yourself. It can lead to injury.

Torsion springs are tough to change. If you have had no definite hands on training on how to replace your tension spring, do not even think about it.

While a lot of garage door repairs necessitate a educated technician to make the repairs, there are some things that a home owner may productively work on. One of those objects is the stop/reverse lights.
At the bottom of the tracks on either side of your garage door opening, you will most likely see a set of stop/reverse lights. These lights are in reality a transmitter plus a receiver of infrared beams. If the beam is interrupted your door will stop going down, turn around and go all the way back up. As a rule your garage door light will flash when this happens.
Occasionally your garage door eyes will stop and reverse your door when there is no apparent reason. One reason might be that your stop/reverse units have been bumped and are no longer pointing at each other. If you think that is the problem, make use of the set screws or wing nuts to correct the lights, not a hammer.
The primary reason that your door will stop and reverse is that your "eyes" are functioning precisely as they are supposed to. There is an object blocking your garage door. Sometimes the object that is blocking the door is not apparent, so carefully look around your garage door opening. Ultimately you'll figure out what it is.
If there's nothing apparently blocking your garage door, don't pull your hair out. There's one more thing to try. Take a paper towel and wipe the lenses on your stop/reverse lights. Now and again condensation or a small bug or dust particle will get on the lense and cause all your stop/reverse problems.
Another reason of an inconsistent garage door is that your opener's logic board or gear sprocket has malfunctioned.
If your opener is the problem you may be happy to know that you probably do not have to replace it. Components are accessible to garage door technicians who will repair your opener at a fraction of the price of a new opener.
