Garage doors have two main types of springs. Extension springs run above the horizontal tracks on either side of your garage. They get their power by extending. Torsion springs run along a bar you can observe above your garage door when it is closed. Torsion springs get their strength from twisting.
If one of springs is damaged it could be challenging or completely unattainable for you or your opener to open your door. This attribute of garage doors is just what can turn a appealing day into somewhat of a foul day, particularly in case your car is stuck in your garage and you want to go someplace, like work.

There are some items regarding your garage door that you can trouble shoot and repair youself. If you have a garage door opener then you also have some type of interrupter device that can keep your door from closing if something is in the way. Generally they are stop/reverse lights.
Perhaps essentially the most common interrupter gadget is a set of "eyes" which are mounted on the garage door track. They point to one another making use of an infrared beam. One is a transmitter and the other is a receiver. If the receiver can't get what the transmitter is delivering then the garage door will certainly stop and usually turn around. Often this is accompanied by the garage door opener light flashing.
Every now and then your garage door eyes will stop and reverse your door when there is no apparent reason. One cause can be that your stop/reverse units have been bumped and are no longer pointing at each other. If you suspect that is the problem, use the set screws or wing nuts to correct the lights, not a hammer.
The reason the stop/reverse system is there is that it stops your door from closing when something is in its path. Test your garage door opening and take away any item that may possibly be blocking your garage door. It will probably prove successful.
If you've spent quite a period looking for the item that is blocking your garage door and nothing seems to work, try cleaning the lenses of your stop/reverse lights with a paper towel. Perhaps a bug or mark has gotten on the lense.
Another cause of an erratic garage door is that your opener's logic board or gear sprocket has malfunctioned.
A DIY type of home-owner can substitute these things, but you may want the proper parts. They are often troublesome, but not inconceivable to find.
