f the garage door was placed on a set of rollers without any resistance, it would be difficult to control the speed at which the door closed. This would make lifting the door open excessively hard. The torsion springs and tensioning cables that are in place are the two main components that allow the door to be moved without a lot of effort on your part.
The springs, situated over the mounting rod and attached to the door via a steel cable, are an especially crucial point of operation. When something goes wrong, there is no doubt you will see the difference in how your garage door operates. Here are a few of the most common issues that can arise and what you need to know about making garage door spring repairs.
Problem: Spring are making a screeching noise when the door is opened or closed.
Cause: This is usually a problem that is related to older garage doors that have not been properly lubricated for some time. The springs may even appear rusted or aged when you take a closer look. The sound of the springs opening and retracting will create a telltale squeak or screech.
Solution: Use a high-quality lithium grease, or lubricating spray to generously coat the springs. Grease the springs while they are closed, but also while they are fully extended to ensure the entire spring is coated with lubrication.
Problem: One or both of the springs are broken, which means there is no tension when the door is open and shut.
Cause: Broken torsion springs can be caused by a few different things. The springs can wear out and break after years of excessive use or they can become damaged when the door becomes jammed and the supporting cables are compromised.
Solution: If the torsion springs are broken, they must be immediately replaced. The process to replace the springs can get pretty complicated, including having to support the weight of the door during installation. Therefore, it is best to trust a garage door repair professional for this task.
Problem: Springs do not provide enough tension when door is closed to keep it from slamming shut.
Cause: The spring has been overextended and is no longer providing enough resistance to support the weight of the door.
Solution: During garage door jams, the springs have to accept the brunt of the weight for an extended period of time. This can lead to over-extension of the spring causing irreparable damage. If you notice that the usually tightly wound spring is not contracting as it should, the torsion springs will have to be replaced.
By educating yourself about some of the working components of your garage door, you will be better equipped to handle issues that arise. If you have further questions, be sure to talk to a garage door repair professional in your area.
