How to measure garage door extension springs?

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 resources you need to keep your garage door operating safely and efficiently. Today, we’re tackling a common question: How to measure garage door extension springs. Correctly identifying your extension springs is crucial for ordering replacements and ensuring the proper balance and functionality of your garage door. Let’s dive in!

Why Accurate Spring Measurement Matters

Garage door extension springs are under immense tension, and their size directly correlates to the weight they can safely lift. Using the wrong springs can lead to several problems, including:

• Door imbalance, making it difficult to open and close.
• Premature wear and tear on the garage door opener.
• Potential for dangerous spring breakage, causing injury or property damage.

Therefore, accurate measurement is paramount for safety and optimal performance. While we always recommend professional assistance, this guide will help you understand the process if you choose to tackle it yourself.

Safety First

WARNING: Garage door springs are under extreme tension and can cause serious injury or death if mishandled. If you are not comfortable working with springs, please contact a qualified garage door technician like those at MM Garage Door Repair Utah.

Before you begin, take these precautions:

• Disconnect the garage door opener: Unplug the opener from the electrical outlet to prevent accidental operation.
• Wear safety glasses: Protect your eyes from flying debris.
• Use proper tools: Avoid using makeshift tools that could slip or break.
• Never attempt to release the tension on the springs yourself: This requires specialized tools and expertise.

Tools You’ll Need

To accurately measure your garage door extension springs, you’ll need the following tools:

• Measuring tape: A standard measuring tape will work fine.
• Scale (optional): To weigh the garage door if the weight is unknown.
• Notebook and pen: To record your measurements.

Step-by-Step Guide to Measuring Extension Springs

Follow these steps carefully to obtain accurate measurements:

Step 1: Determine the Spring Type

Extension springs are typically located above the horizontal tracks on either side of the garage door. They extend and contract as the door moves. Identify if you have standard extension springs or looped end extension springs. This will affect how you measure the length.

Step 2: Measure the Spring Length

Measure the length of the spring while it is relaxed (not stretched). This is the most crucial measurement. For standard extension springs, measure from the end of one hook to the end of the other hook. For looped end springs, measure from the end of one loop to the end of the other loop. Record this measurement in inches.

Step 3: Measure the Spring Diameter

Measure the outside diameter of the spring. This is the distance across the coil from one side to the other. Measure to the nearest 1/16 inch. Record this measurement.

Step 4: Count the Number of Coils

Count the total number of coils in the spring. This can be a bit tedious, but it’s important for determining the spring’s wire size. Record the total number of coils.

Step 5: Determine the Spring Wire Size (Optional but Recommended)

The wire size is the thickness of the wire used to make the spring. While not always necessary, knowing the wire size can help ensure you get the correct replacement spring. The most accurate way to determine the wire size is by using a wire gauge. However, you can also estimate it based on the spring’s color code (see below) and the other measurements you’ve taken.

Step 6: Determine the Spring’s Lifting Capacity

To determine the spring’s lifting capacity, you’ll need to know the weight of your garage door. If you don’t know the weight, you can weigh the door using a bathroom scale. Place the scale under the door and carefully lower the door onto the scale. Be sure to support the door on both sides to prevent it from falling. Divide the weight reading by two to get the approximate weight each spring needs to lift. Alternatively, you can look for a sticker on the door that indicates its weight.

Understanding Spring Color Codes

Extension springs are often color-coded to indicate their lifting capacity. Here’s a general guide to common color codes:

• White: 100 lbs
• Green: 110 lbs
• Yellow: 120 lbs
• Blue: 130 lbs
• Red: 140 lbs
• Brown: 150 lbs
• Orange: 160 lbs
• Gold: 170 lbs
• Light Blue: 180 lbs

Note: These color codes are not standardized across all manufacturers, so it’s always best to confirm the lifting capacity based on your door’s weight and the spring’s measurements.

Final Solution

Once you have all the measurements (length, diameter, wire size or coil count, and lifting capacity), you can use this information to order replacement springs. When ordering, be sure to specify whether you need a right-wound or left-wound spring. This is determined by which direction the coils wind when viewed from the end of the spring. If you are unsure, it is best to order a pair of springs, one of each wind direction.

Remember to replace both springs at the same time, even if only one is broken. This ensures balanced operation and prevents premature failure of the remaining spring.

FAQs

Q: Can I use a spring with a slightly different length?

A: It’s best to use a spring with the exact same length as the original. A slight difference (e.g., within an inch) might be acceptable, but it’s crucial to ensure the spring’s lifting capacity is correct.

Q: How do I know if my springs are broken?

A: Common signs of broken springs include a garage door that is difficult to open or close, a door that slams shut, or visible gaps in the spring coils.

Q: Can I replace the springs myself?

A: While it’s possible to replace extension springs yourself, it’s a dangerous task that should only be attempted by experienced individuals with the proper tools and knowledge. We strongly recommend contacting a professional garage door technician.
