Understanding Garage Door Springs

Garage door springs are under immense tension, and when they break, they can release that energy with explosive force. There are two main types of garage door springs: torsion springs and extension springs. Torsion springs are mounted above the garage door opening, while extension springs run along the sides of the door. Identifying the type of spring you have is crucial before attempting any repairs. This guide primarily focuses on replacing torsion springs, as they are more common and generally require more specialized tools and knowledge. However, the safety precautions apply to both types.

Safety First: A Critical Warning

Before we proceed, let’s reiterate the importance of safety. Garage door springs are extremely dangerous. Attempting to replace them without the proper tools, knowledge, and experience can lead to serious injury or even death. If you are not comfortable working with high-tension springs, please, please call a professional. MM Garage Door Repair Utah is available 24/7 to assist you. Our number is 801-418-9217.

Tools and Materials Needed

If you’re determined to proceed, gather the following tools and materials:

• New garage door spring (correct size and type)
• Winding bars (correct size for your spring)
• Safety glasses
• Work gloves
• Adjustable wrench
• Socket set
• Vice grips
• Ladder
• Marker or tape

Ensure you have the correct replacement spring. Measure the old spring’s length, wire diameter, and inside diameter. These measurements are crucial for selecting the right replacement. Using the wrong spring can lead to improper door operation and potential damage.

Step-by-Step Guide to Replacing a Torsion Spring

Follow these steps carefully, and remember to prioritize safety above all else.

Step 1: Secure the Garage Door

Before you begin, ensure the garage door is fully closed. Clamp the door to the tracks using vice grips or C-clamps to prevent it from accidentally opening during the repair process. This is a critical safety measure.

Step 2: Loosen the Old Spring

Insert one winding bar into the winding cone of the broken spring. Use the other winding bar to loosen the set screws on the winding cone. Slowly and carefully unwind the spring by inserting the second winding bar and alternating between the two. This releases the tension in the spring. This step is extremely dangerous, and requires extreme caution. Keep your face and body away from the spring during this process.

Step 3: Remove the Old Spring

Once the spring is fully unwound, loosen the set screws on the stationary cone (the cone attached to the center bracket). Slide the spring off the torsion tube. If the spring is in multiple pieces, carefully remove all fragments.

Step 4: Install the New Spring

Slide the new spring onto the torsion tube, ensuring it’s oriented correctly (the winding cone should be on the same side as the winding cone of the old spring). Secure the stationary cone to the center bracket using the set screws.

Step 5: Wind the New Spring

This is the reverse of unwinding the old spring. Insert one winding bar into the winding cone. Wind the spring the correct number of turns, as specified by the spring manufacturer or based on the door’s height (typically around 7.5 turns for a standard 7-foot door). Insert the second winding bar and alternate between the two, maintaining control of the spring at all times. This step requires significant strength and precision.

Step 6: Secure the Winding Cone

Once the spring is fully wound, tighten the set screws on the winding cone securely. Remove the winding bars carefully.

Step 7: Test the Door

Remove the vice grips or C-clamps from the garage door tracks. Slowly lift the door manually to test its balance. If the door is difficult to lift or falls quickly, the spring tension may need to be adjusted slightly. Make small adjustments to the winding and re-test until the door is properly balanced.

Tips for a Successful Spring Replacement

• Double-Check Measurements: Ensure the replacement spring matches the specifications of the old spring.
• Lubricate the Spring: Apply a garage door lubricant to the spring to reduce friction and extend its lifespan.
• Replace Both Springs: If one spring breaks, it’s often recommended to replace both springs at the same time. This ensures balanced operation and prevents the other spring from failing shortly after.
• Consult the Manual: Refer to your garage door opener’s manual for specific instructions and safety guidelines.
