If your garage door's spring breaks, stops working properly, or snaps, you'll lose the ability to open and close your garage door. This could happen due to a variety of issues, like normal wear and tear or from extreme temperature changes in a short amount of time. Spring replacements require a quick response from a garage door provider near you. Contact The Home Depot and a local, background-checked technician will respond within 24 hours.
The power to your garage is out with the door shut, and you need to get your car out or you'll have to take a bus. You'll notice a cord—usually with a red handle—dangling down from the guide track that the opener uses to open and close the door. This is the manual override. Once pulled, it allows you to open and close the door with your own power in the form a little elbow grease.
