If your garage door is opening and closing slower than usual, shows wear and tear on the springs, and has loose bolts or screws, then it’s time to repair it!
Check your mounting brackets for loose bolts and screws. If they are loose, tighten them.
Check to see if the vertical tracks are straight and the same height. If you have horizontal tracks, check to make sure that they are slanted down toward the back of the garage. If you see an issue, loosen the mounting brackets, tap the tracks back into position, and then re-tighten the mounting brackets. Be sure to clean out any grease or dirt buildup inside of them or on the rollers and then wipe them dry after you clean them.
Checks the springs. A single-car garage will only have one spring, but a two-car garage will have two springs. These torsion springs operate the roll-up doors using cables and pulleys. For two-car garage doors, you’ll want to pull the cable further through the plate that is above the door and then knot the end so that the tension holds.
For a one-car garage door, you’ll want to call a professional because there is a high risk of injury in repairing the spring. If you have a swing-up door, simply move the hooks to the next notch to adjust the tension on the springs.
Check the garage door opener. If your garage door opens slowly or doesn’t open at all and you’ve done all of the above repairs, the door opener itself is most likely the issue as modern models use a motor that opens and closes the door via a drawback carriage just above the door.
Check the battery in your garage door remote. If you are stuck outside and the door won’t open, replace the battery as they aren’t meant to last more than a year before needing to be replaced.
If the battery is in good shape and the door still won’t open, your garage door remote may need to be reprogrammed and resynced to your main door opener. See your manufacturer’s website for information on how to reprogram your specific model.
If you’ve done all of this and still have issues, it might be time to replace the motor itself. The motors cost about $100 and can be found at most hardware stores; however, if you can’t fix it at the moment, use the red cord hanging down from the motor. This will allow you to open the door manually.
