Understanding the Problem
My one-piece garage door does not stay up when I open it by hand; it wants to come back down slowly. Can I fix that myself, or do I need to call someone? The answer often lies in the spring system. When a garage door fails to remain open, it typically indicates an issue with the door’s springs. A broken or worn-out spring, or improper tension levels, could be causing this problem.
Identifying Broken Springs
Whenever this problem arises with a one-piece garage door, the first thing to check is for broken springs. One-piece garage doors can have multiple extension springs, typically two on each side. A broken spring may not be immediately visible, so it’s crucial to examine them closely. Open the door fully and inspect for any separation in the springs, as this is often more evident when the springs are fully extended.
Understanding Safety Mechanisms
One-piece garage door springs, or extension springs, are equipped with built-in safety mechanisms that prevent them from extending beyond their intended capacity. Two rods are located inside the spring, which slide along one another. When the spring reaches maximum extension, the rods hook together, halting further movement. If you observe a broken extension spring, the safety rods will be visible, indicating that replacement is needed.
Adjusting Spring Tension
Another common issue might be insufficient tension on the springs when the door is fully open. Adequate tension is necessary for the door to remain in the upright position. If the door lacks this tension, you’ll notice slack in the chain that connects to the bottom of the spring. In the case of insufficient tension, you’ll need to adjust the springs to ensure the door stays up securely.
Preparing for Adjustment
Before attempting to adjust the springs, it’s crucial to approach this task with caution. These springs can be dangerous if mishandled. Start by ensuring the garage door is in the fully open position. If you have a garage door opener, you may need to disengage it by pulling the emergency release cord. This will allow you to open the door freely and maintains it in the open position while you work.
Adjusting the Springs Safely
With the door in the fully up position, proceed to adjust the springs by examining the chain connected to the bottom of the extension spring. The chain runs down to the wall and is typically screwed into a piece of wood. Check the hook attached to the spring and determine the link it connects to. Move the hook down several links to tighten the chain and ensure proper tension in the springs.
Seeking Professional Help
If these steps do not resolve the issue, you may need to call a garage door technician. A professional can assess whether the springs are inadequate for the weight of your door or if there is another underlying issue. While DIY fixes can save time and money, safety must always come first. If in doubt, contacting a garage door company is advisable to ensure proper repairs and avoid personal injury.
