Modern garage doors have rollers or levers that will open the door, and these mechanisms could be far more complex than the old systems that you may have grown up with in your parent’s home. Modern garage doors have tracks, motors and pulleys, as well as springs, sensors and remotes or keypads �” all things that could go wrong.
Modern garage doors do need some servicing to keep them safe, quiet and secure. Some parts will need replaced from time to time. The good news is that parts are easy to come by, and only a modest amount of mechanical ability is required to fit replacement parts. The hardest part, for most people, is figuring out what the parts are so that you can order the right thing.
There are many retailers that sell garage door repair parts, and if you have an understanding of how the door works and are able to put the new parts in yourself then you could save a lot of money, and get the pride of knowing that you did the repair yourself.
Some repairs are simple. If the remote control and the switch both fail to operate the door, then check that the motor is still connected to the power, and that there are no tripped circuit breakers or blown fuses. These are the most common causes of problems.
If the door doesn’t close fully, or it reverses before it hits the ground, then it could be that the close-limit or close-force settings require adjustment. There are many sensors in modern garage doors, and problems with these cause just as many issues as broken rollers, tracks or springs. Performing a quick check of the settings on these could save you from wasting time and money on replacing garage door repair parts for some of the more expensive systems in the door.
