A broken garage door spring may not be immediately visible, as the spring is usually located above the garage door, either at the center or on either side of the door. However, there are some signs that indicate that the spring is broken.
When a garage door spring breaks, it loses tension, and the door may become difficult or impossible to open or close. You may also hear loud popping or banging noises when opening or closing the door, and the door may appear to be crooked or uneven when it moves.
If you suspect that your garage door spring is broken, it's best to contact a professional garage door repair company for assistance. Attempting to repair or replace the spring on your own can be dangerous and cause further damage to your garage door or other parts of your property.
