How do i know what size garage door spring i need?

Welcome to the MM Garage Door Repair Utah blog! As your trusted local garage door experts, we’re here to guide you through the often-confusing world of garage door maintenance and repair. One of the most crucial components of your garage door system is the spring. Choosing the correct size spring is vital for safe and efficient operation. In this post, we’ll answer the common question: “How do I know what size garage door spring I need?” Let’s dive in!

Why is the Right Garage Door Spring Size Important?

Using the wrong size garage door spring can lead to a host of problems. Too weak a spring will struggle to lift the door, putting strain on the opener and potentially causing it to fail prematurely. On the other hand, too strong a spring can cause the door to slam down, posing a safety hazard and damaging the door itself. Correct spring size ensures smooth, balanced operation, extending the lifespan of your entire garage door system and, most importantly, keeping you and your family safe.

Safety First: A Crucial Warning

Before we proceed, it’s absolutely essential to emphasize the dangers of working with garage door springs. These springs are under immense tension and can cause serious injury or even death if mishandled. We strongly recommend that you do not attempt to replace or adjust garage door springs yourself unless you have extensive experience and the proper tools. If you’re unsure about any step, please contact MM Garage Door Repair Utah at 801-418-9217 for professional assistance. Your safety is our top priority.

Steps to Determine Your Garage Door Spring Size

If you are experienced and have the proper tools, here’s how you can determine the size of your garage door spring. Remember, proceed with extreme caution.

Step 1: Gather Information

Before you even approach the garage door, gather as much information as possible. Look for any existing labels or markings on the spring itself. These might contain information about the spring’s dimensions and weight capacity. Also, note the following:

• Door Weight: If possible, find the manufacturer’s specifications for your garage door model. This will provide an accurate weight. If not, you can estimate the weight based on the door’s material (steel, wood, etc.) and size.
• Door Height and Width: Measure the height and width of your garage door.
• Spring Location: Determine whether you have torsion springs (mounted above the door) or extension springs (running along the sides of the door). The method for identifying the size differs slightly depending on the spring type.

Step 2: Identifying Torsion Spring Size

Torsion springs are located above the garage door opening. To determine their size, you’ll need to measure the following:

• Wire Size: This is the diameter of the spring wire. Use two wrenches to gently pry apart one coil of the spring. Then, use calipers to measure the wire diameter to the nearest 1/16 of an inch. If you don’t have calipers, you can use two wrenches to gently pry apart one coil of the spring. Then, use a tape measure to measure the outside diameter of 10 coils. Divide that number by 10 to get an approximate wire size.
• Inside Diameter: Measure the inside diameter of the spring. This is the distance across the inside of the spring coil.
• Spring Length: Measure the overall length of the spring.

Once you have these measurements, you can use a garage door spring chart or online calculator to determine the spring’s weight capacity. These charts correlate wire size, inside diameter, and length to the spring’s lifting force.

Step 3: Identifying Extension Spring Size

Extension springs are located along the sides of the garage door. To determine their size, you’ll need to measure the following:

• Wire Size: As with torsion springs, measure the wire diameter using calipers or the 10-coil method.
• Inside Diameter: Measure the inside diameter of the spring.
• Spring Length: Measure the relaxed length of the spring (when it’s not stretched).

Extension springs are also often color-coded to indicate their weight capacity. Common color codes include:

• Brown: 60 lbs
• Orange: 70 lbs
• White: 80 lbs
• Green: 90 lbs
• Yellow: 100 lbs
• Blue: 110 lbs
• Red: 120 lbs
• Brown: 130 lbs

However, relying solely on color codes can be misleading, as they can fade or be painted over. Always verify the size with measurements.

Step 4: Matching the Spring

Once you have the measurements, you need to find a replacement spring that matches the specifications. It’s crucial to match the wire size, inside diameter, and length as closely as possible. A slight variation in length might be acceptable, but the wire size and inside diameter should be exact.

FAQs About Garage Door Springs

Q: Can I use a slightly stronger spring than the original?

A: It’s generally not recommended. Using a significantly stronger spring can cause the door to slam down and damage the opener or door. A slightly stronger spring might seem appealing, but it can create an imbalance in the system.

Q: How long do garage door springs last?

A: The lifespan of a garage door spring depends on several factors, including usage frequency, door weight, and maintenance. On average, springs last for 7-12 years or around 10,000 cycles (one cycle is one opening and closing of the door).

Q: Should I replace both springs at the same time?

A: Yes, absolutely. Garage door springs work in pairs. If one spring breaks, the other is likely to fail soon as well. Replacing both springs ensures balanced operation and prevents future breakdowns.
