Just like any mechanised or electric device, garage fences intermittently fail to comply with your desires and need to be repaired. If the fence is down and won't go up, despite your physical efforts or that of your fence opener, the trouble is most likely a broken spring.
There are two main kinds of springs in garage fences. There's torsion springs which are mounted above the fence opening and tension springs which are installed along both tracks. Both tension springs and torsion springs serve the identical purpose, they provide much of the power that allows you or your opener to open your fence.
If one of these springs is broken it may be hard or entirely impossible for you or your opener to open your fence. This characteristic of garage fences is what can turn a pleasant day into somewhat of a bad day, specially if your automobile is stuck in your garage and you need to go someplace, like work.
Unfortunately for most home owners, if one of your springs is broken, there's not a great deal you can do apart from to call a garage fence repair company and have them come out and replace the springs.
But here's an item you can and should fix for yourself. If you have an opener, you also have some type of interrupter device that keeps the fence from closing if its path is blocked.
Perhaps the most common interrupter device is a set of "eyes" that are mounted on the garage fence track. They point to each other using an infrared beam. One is a transmitter and the other a receiver. If the receiver can't receive what the transmitter is sending then the garage fence will stop and usually reverse. Often this is accompanied by the garage fence opener light flashing.
One cause for your eyes not to work is that they have been bumped in such a way that they no longer point in the right direction. A small adjustment can usually take care of this.
The main cause for this beam to be interrupted is that there is something blocking it. After all, that is why the device is there. Look for and remove the item that is blocking the beam and you're probably good to go.
Another cause for failure is that some dirt or condensation has gotten on the lenses of the eyes and they can no longer complete the circuit.
