There are two Garage doors have two major types of springs. The most common type of spring is a torsion spring. Torsion springs are installed above the door opening. Tension springs are installed alongside the garage door's horizontal tracks. Both kinds of springs do the identical thing. They provide most of the power that causes your door to open.

The malfunction of either one of the two springs on your garage door can most likely keep you from being capable to open your garage door.

Regrettably for most home owners, if one of your springs is broken, there's not much to do except to call a garage door replacement business and have them come out and change the springs.

There are some things about your garage door that you can trouble shoot and repair youself. If you have a garage door opener then you also have some kind of interrupter device that will stop your door from closing if an object is in the way. As a rule they are stop/reverse lights.

At the bottom of the tracks on either side of your garage door opening, you may 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 broken your door will stop going down, reverse and go all the way back up. As a rule your garage door light will flash when this happens.

From time to time your garage door eyes will stop and reverse your door when there's no apparent reason. One cause 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, use the set screws or wing nuts to adjust the lights, not a hammer.

The main reason that your door will stop and reverse is that your "eyes" are operating precisely as they are designed to. There is an object blocking your garage door. Sometimes the object that is blocking the door is not evident, so carefully look around your garage door opening. Eventually you'll figure out what it is.

If there's nothing obviously blocking your garage door, don't tear your hair out. There's one more thing to try. Get a paper towel and wipe the lenses on your stop/reverse lights. Occassionally condensation or a small bug or dust particle may get on the lense and cause all your stop/reverse problems.

If your door is still acting irradically the trouble may not be your stop/reverse lights after all. You may have a issue with the logic board or the gear sprocket in your opener.

It is feasible for a home owner to change both the gear sprocket and logic board. The trouble is getting the correct parts and learning just how to replace each item. More often life is less difficult if you just phone a garage door technician to complete the replacement. They've helped hundreds of people and they can help you too.
