SNAP... bang... boom. That is the sound of a garage door torsion spring breaking. It can be a very loud noise that sounds like a firecracker or gunshot. Springs are rated for a certain number of cycles and are the first thing that will break in your garage door assembly. Broken springs are the #1 source of customer calls for garage door repair companies. If you have a broken spring, you should NEVER try to open the door, as it can be very dangerous. This repair should be left to a professional or someone with the right tools and skills.
If this is the problem then you will be able to tell by seeing if your garage door rollers are literally off track. If your garage door panels are not damaged, then you do not need to replace your door. However, the rollers do need to be put back on the track which should be done by a professional.

Garage doors are able to move due to a counterbalance system that usually consists of a torsion spring. We often find incorrect springs have been installed which result in an unsafe door that you may not be able to open manually when needed. The balance of your garage door should be tested annually to reduce wear on your garage door opener and ensure it can be opened if an emergency situation arises. Because of the dangers involved with torsion springs, garage door spring repair and installation should only be done by experienced professionals like our Medics.
