How does garage door spring work?

Welcome to the MM Garage Door Repair Utah blog! As your trusted local garage door experts, we’re dedicated to providing you with the knowledge and services you need to keep your garage door operating safely and efficiently. Today, we’re tackling a crucial component of your garage door system: the springs. Many homeowners don’t realize the vital role these springs play, or how they actually work. So, let’s dive in and unravel the mystery of garage door springs!

How Does a Garage Door Spring Work?

Garage door springs are the unsung heroes of your garage. They do the heavy lifting, literally! Their primary function is to counterbalance the weight of the garage door, making it easy to open and close, either manually or with the assistance of an opener. Without properly functioning springs, your garage door would be incredibly difficult, if not impossible, to operate.

There are two main types of garage door springs: torsion springs and extension springs. Let’s explore each type in detail.

Torsion Springs

Torsion springs are typically mounted horizontally above the garage door opening. These springs work by winding and unwinding. When the door is closed, the torsion spring is tightly wound, storing energy. As the door opens, the spring unwinds, releasing that stored energy to help lift the door. The amount of tension in the spring is carefully calibrated to match the weight of the door.

Here’s a breakdown of how torsion springs work:

1. Winding: When the garage door is closed, the torsion spring is wound tightly around a torsion tube. This winding process stores potential energy.
2. Lifting: As the garage door begins to open, the torsion spring unwinds, releasing the stored energy. This energy assists in lifting the heavy door, reducing the strain on the opener motor (or your back, if you’re opening it manually).
3. Counterbalancing: The torsion spring is precisely calibrated to counterbalance the weight of the door. This ensures that the door remains balanced at any point during its travel, preventing it from slamming shut or being difficult to lift.

Torsion springs are generally considered safer and more durable than extension springs. They also tend to provide a smoother and quieter operation.

Extension Springs

Extension springs are located on either side of the garage door, running along the horizontal tracks. These springs work by stretching and contracting. When the door is closed, the extension springs are stretched to their maximum length, storing energy. As the door opens, the springs contract, releasing that energy to help lift the door.

Here’s how extension springs function:

1. Stretching: When the garage door is closed, the extension springs are stretched, creating tension and storing potential energy.
2. Lifting: As the garage door opens, the springs contract, releasing the stored energy. This energy assists in lifting the door.
3. Safety Cables: Extension springs should always be installed with safety cables running through them. These cables prevent the spring from becoming a dangerous projectile if it breaks.

While extension springs are often less expensive than torsion springs, they generally have a shorter lifespan and can be more dangerous if they break. The safety cables are absolutely crucial for preventing injury in case of spring failure.

Why is Spring Tension Important?

Proper spring tension is absolutely critical for the safe and efficient operation of your garage door. If the tension is too low, the door will be difficult to open and may not stay open. If the tension is too high, the door may slam shut or be difficult to close. Incorrect tension can also put undue stress on the garage door opener, leading to premature failure.

What Happens When a Garage Door Spring Breaks?

A broken garage door spring is a serious issue. You’ll likely notice that the door is extremely heavy and difficult to lift, or that the opener struggles to operate the door. Never attempt to operate a garage door with a broken spring. This can cause further damage to the door and opener, and can also be extremely dangerous.

Safety Note

Working with garage door springs is extremely dangerous and should only be performed by trained professionals. The springs are under immense tension, and improper handling can result in serious injury or even death. Do not attempt to repair or adjust garage door springs yourself. Always contact a qualified garage door technician.

FAQs About Garage Door Springs

Q: How long do garage door springs last?

A: The lifespan of a garage door spring depends on several factors, including the quality of the spring, the frequency of use, and the maintenance performed. On average, torsion springs last for 15,000 to 20,000 cycles (one cycle is one opening and closing of the door), while extension springs typically last for 5,000 to 10,000 cycles.

Q: How do I know if my garage door spring is broken?

A: Common signs of a broken garage door spring include a loud bang, a door that is difficult to open or close, a door that is crooked or uneven, or a visible break in the spring.

Q: Can I replace just one garage door spring?

A: It’s generally recommended to replace both garage door springs at the same time, even if only one is broken. This is because the springs work together to balance the door, and replacing only one spring can lead to uneven wear and tear and a shorter lifespan for the new spring.
