10.13 Slowly pull down on the winding bar until the garage door rises 3" and the roller hits the vise grip on the track. The door will usually drop back down and raise the bar. If it doesn't, lift the end of the bar until the door closes. If the door comes up by itself when you hold the bar lightly, the springs are either over wound or they are too strong. You may need to remove 1/4 to 1/2 turns from the springs. If the door comes up on its own, you either have to many turns on the springs or you have the wrong springs. This can be very dangerous. We recommend getting professional help. Removing the winding bar could cause the garage door to knock you off the ladder.
Although garage door springs can break during any season and at any time, they most commonly break during the winter. This has to do with the temperature change. When the temperature sinks below a specific threshold, the metal will contract. This means it’s extremely possible for your door springs to shrink slightly during the winter months. This is hard on the springs and makes them more likely to break. https://youtu.be/Z_eZc-kh40c
