Wrench: A component used to loosen screws and secure springs.
Screwdriver: used to unscrew set screws.
Torsion spring adjustment device: used to adjust the tension of the spring.
Pad: Used to support the door body to release the tension of the spring.

Lubricant: Used to lubricate door rails and other moving parts.

Safety Precautions:
Wear gloves and goggles: Always wear gloves and goggles during operations to protect your hands and eyes from possible injury.
Disconnect power: Before beginning operation, be sure to disconnect power to the garage door to avoid the risk of electric shock.
Handle with caution: Use caution when handling to avoid injury or damage.
Get help: If necessary, seek professional help to ensure safe and correct operation.
By being prepared with the proper tools and materials, and following safety precautions, you can safely and effectively replace your garage door spring, ensuring proper operation of your garage door and the safety of your home.


Step 2: Disconnect power to the garage door

Power outage is crucial in the process of replacing garage door springs, and its importance is mainly reflected in the following two aspects:

To avoid accidental electric shock:
During the garage door spring replacement process, you will need to come into contact with the power supply and controls of the electric garage door system, which may pose a risk of accidental electric shock. Garage door systems usually use high-voltage power supplies. If you accidentally come into contact with power components during operation, it may cause serious electric shock injuries or even life-threatening injuries. Therefore, a power outage is one of the key steps to ensure operational safety.

How to cut off power:
Typically, you can disconnect power to your garage door by:

Disconnect power switch: Most garage door systems are equipped with a power switch that you can turn off to cut off the power supply.
Unplug the electrical outlet: If your garage door does not have a dedicated power switch, you can simply unplug the electrical outlet to block the power supply.
You can safely replace the garage door springs only after ensuring that the power is off. Remember, safety always comes first and be sure to follow proper procedures and safety measures to keep yourself and others safe.


Step 3: Release the tension of the original spring

Releasing the tension on your garage door springs is one of the most dangerous steps in the spring replacement process. Springs store a large amount of energy, and if the tension is not released correctly, it can cause the spring to suddenly release, causing serious injury. Therefore, before releasing the tension, always use extreme caution and follow these steps:

Warning about the potential dangers of original springs:
The spring may release suddenly: Because the spring stores a large amount of energy, if it is released improperly, it may spring back quickly, causing physical injury.
Severe crush injuries: When tension is released, the spring may suddenly move or twist, causing serious crush injuries.

Ways to release tension:
Using a wrench: Insert the wrench into the adjustment hole of the spring, then slowly turn the wrench to gradually release the tension. Make sure to keep your hands and body away from the spring to prevent sudden release.
Use a torsion spring adjuster: If you have a torsion spring adjuster, you can use it to slowly release the tension from the spring. Again, be sure to operate safely and stay out of the path of the spring's movement.
After you have released the spring tension, be sure to remove the spring carefully and ensure that no other parts or persons are in the path of the spring. Safety first, always remember this.


Step 4: Remove the original spring

When removing a garage door spring, you need to follow these steps:

Loosen the screw connecting the spring
Using the correct size wrench, locate the screw that attaches the spring.
Loosen the screws one by one, but do not unscrew them all the way to avoid the spring suddenly falling off.

Unlock the spring from the bearing bracket
Make sure the spring tension is fully released.
Carefully unhook the spring from the bearing bracket, making sure the spring does not pop open.
Be careful during the operation to avoid injury caused by sudden spring pop-ups.
If the spring is too tight and cannot be easily untied, stop operation and seek professional help.
During disassembly, make sure there are no other people around to avoid accidental injury.
By following the steps above, you can safely remove your garage door springs and prepare them for replacement with new ones.


Step 5: Install the new spring

Installing new garage door springs requires caution to ensure safe operation. Here are the detailed steps for installing a new spring:

Make sure the power to the garage door is disconnected to avoid accidental activation.
Get your new garage door springs ready and the tools needed.

Install new spring into bearing bracket
Install one end of the new spring onto the bearing bracket, making sure the spring is oriented correctly.
Insert the spring at the other end into the corresponding hole in the door body.

connecting screws
Use a screwdriver to secure the spring to the bearing bracket. Make sure the screws are secure, but not too tight to avoid damaging the spring or bracket.

Adjust spring tension
Use a torsion spring adjuster to gradually adjust the tension of the spring until the proper tension is reached. Tension adjustments should be made based on the weight of the garage door and the size of the springs.

Test door operation
Open and close the garage door manually a few times to make sure the door is functioning properly and there are no abnormalities.

During installation, be careful to ensure that your fingers do not get caught in the spring.

The tension of the spring must be appropriate. If it is too tight, it will be difficult to open the door, and if it is too loose, it will affect the balance and operation of the door.

If you are unsure about spring installation and adjustment, it is recommended to seek professional assistance.

By following the steps above, you can safely and effectively install new garage door springs and get your garage door back up and running.


Step 6: Reconnect power

Before reconnecting power to your garage door, it is important to make sure that all steps have been completed correctly and that the door is functioning properly. Before reconnecting power, you can double-check the operation of your garage door to make sure it's safe. If any abnormality is found, stop the operation immediately and seek professional help.

Make sure all steps have been completed correctly, including spring installation, screw fixation, and tension adjustment.

Before reconnecting power, make sure the garage door opens and closes smoothly without any unusual sounds or resistance.

If you find that the door is running abnormally or not smoothly, you should stop the operation and check whether there are any missing or wrong steps.

If you are unsure about the operation procedure or there is a safety hazard, please stop the operation immediately and seek professional help.
