How can I test the balance of my garage door?

To test the balance of your garage door, disconnect the opener by pulling the release cord, then manually lift the door. If the door stays in place, it's balanced. If the door rises or falls, it may be out of balance, indicating that the springs need adjustment. In Thornton CO, Golden CO, or Erie CO, an imbalanced door can damage the opener and other components, so it’s important to have it professionally fixed.
