Garage Door Tension Spring Replacement

Garage door tension springs are essential components that counterbalance the weight of the door, making it easier to open and close. Over time, these springs can weaken or break, compromising the functionality and safety of the garage door.
Replacing garage door tension springs requires technical knowledge and proper safety precautions. This detailed guide will provide you with step-by-step instructions on how to safely replace the tension springs on your garage door.

Safety Precautions

- Disconnect the garage door opener from the power source at the circuit breaker or fuse box. - Engage the manual lock on the garage door to prevent it from accidentally opening. - Wear safety glasses, gloves, and closed-toe shoes while performing the replacement. - Never attempt to replace tension springs without proper experience or training.

Materials Required

- New garage door tension springs (matched to the size and weight of the door) - Adjustable winding bars - Safety cables - Wire cutters - Lubricating spray

Step-by-Step Instructions

1. Determine Spring Type

There are two main types of garage door tension springs: extension springs and torsion springs. Extension springs run parallel to the top of the door, while torsion springs are mounted on a shaft above the door.

2. Remove Old Springs

- Remove the safety cables from the old springs by cutting the wire with wire cutters. - Use adjustable winding bars to carefully unwind the springs. Turn the winding bars clockwise to release tension gradually. - Once the springs are fully unwound, they can be removed from the garage door.

3. Install New Springs

- Attach safety cables to the new springs. - Use adjustable winding bars to wind the new springs counterclockwise to the appropriate tension level. - Consult the manufacturer's instructions for the correct tension setting.

4. Lubricate Springs and Hardware

- Apply a lubricating spray to the springs and all hardware components to reduce friction and extend their lifespan.

5. Reconnect Safety Cables

- Reattach the safety cables to the garage door to prevent the springs from flying off if they break.

6. Reconnect Garage Door Opener (Optional)

- If you have a garage door opener, reconnect it to the power source and reprogram it to adjust to the new springs.

Additional Tips

- Replace both tension springs even if only one is broken to ensure balanced operation. - Springs should be wound to the same tension level. - If you encounter any difficulties during the replacement process, seek professional assistance from a qualified garage door technician.
