2.4 The same is true of Older Overhead, BarCol and Raynor torsion springs that have winding cones with inconsistent hole sizes. If you insert a 1/2" X 18" bar in some of these holes you can move the opposite end of the bar over four inches. Bars in newer cones move less than 1 1/2". I've had many of the older cones spin loose from my bars, the last one generating an $1800 emergency room bill. If your cones are like any of these, or if they have more than 2" of play, leave the job of installing torsion springs to a professional garage door mechanic.
Remove the clamps and pliers from the torsion tube and track, and lift the door about 3 ft. by hand. If the door springs are properly adjusted, the door should stay in place when you let go. If the door falls when you let go, add a quarter turn to each spring. Repeat if necessary. If the door continues to open on its own, release spring tension in quarter-turn increments until the door stays in place when you let go. Then reconnect the opener. https://youtube.com/e/Z_eZc-kh40c
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.
Instead, try other methods that might break the frozen connection between the door and the floor. For example, you can use a heat gun or hair dryer to melt the ice and free the door. Standard de-icing products can also work. And if you are careful not to damage the door or the seal on the bottom of the door, you can use a flat shovel or similar tool to chip away at the ice.
