Removing an electric roller garage door is a challenging task that requires careful attention to safety. Before starting, it is essential to disconnect the power source by unplugging the electric garage door opener or turning off the corresponding breakers or fuses. The process involves removing the tracks on each side while leaving the longer vertical angles supporting the endplates. The next step is to secure the curtain with a rope or strap to prevent it from rolling off and then removing the bolts that secure the endplates to the vertical angle. It is crucial to be cautious when dealing with the tensioned spring, as it can be dangerous. With the bolts removed, the curtain can be lowered slowly, ensuring it is supported to manage the uneven weight distribution. Finally, the vertical angles are removed from the jambs, completing the process of taking down the electric roller garage door.

What You'll Learn
Remove the hood and tracks
Removing the hood and tracks of an electric roller garage door is a challenging process. Before you begin, it is important to disconnect and unplug the electric garage door opener to prevent anyone from accidentally activating the door while you work. You can do this by pulling the opener's release rope and unplugging the opener from its outlet. If your door opener is hard-wired, turn off the corresponding breakers or fuses to cut the power.
Once the power is disconnected, you can start by removing the hood. If there is a hood covering the barrel, open the door and remove it. Next, you will need to remove the tracks on each side, leaving the longer vertical angles that support the endplates. Be cautious when handling the tracks, as they may be sharp.
At this point, you can wrap a strap or rope around the centre of the curtain to secure it and prevent it from rolling off. You may need to raise the forks to free the bolts. With the curtain secured, you can now remove the bolts on each side that secure the endplates to the vertical angle. There are typically two or three bolts on each side. Once the bolts are removed, carefully lower the curtain. It is important to note that the distribution of the door's weight will be uneven due to the springs being off to one side. Therefore, ensure that the winding side is supported with a rope, straps, or by hand as you lower it.
After lowering the curtain, you can now remove the two long vertical angles from the jambs. These steps will effectively remove the hood and tracks of your electric roller garage door.

Secure the curtain with rope or strap
Once you have removed the tracks on each side, you will need to secure the curtain with a rope or strap to prevent it from rolling off the blades or pallets during the removal process.
To do this, wrap a strap or rope around the centre of the curtain. Roll the curtain as needed, then tighten and secure the strap or rope. This will ensure that the curtain remains in place while you move on to the next steps of removing the electric roller garage door.
It is important to note that the distribution of the door's weight will be uneven, as the springs are off to one side. This means that as you pull the curtain away from the header, the winding side will be heavier and may possibly drop. Therefore, it is crucial to have a second person support this end as needed with a rope or straps, or even by hand, as the first person walks this end down a ladder.
The rope or strap should be tightly secured around the curtain to ensure that it does not unravel or shift during the removal process. This step is crucial to ensuring the safety of those involved in the removal process, as well as protecting the door itself from potential damage.

Disconnect the electric door opener
Disconnecting your electric roller garage door is a simple process, but it requires caution. The first step is to ensure the door is closed. If your door is not closing due to a power failure, you can manually pull it down. If you cannot close the door, do not proceed, as the door could drop suddenly and cause injury or damage.
Once the door is closed, locate the release cord. This is usually a red cord with a pull handle, found near the top of the door. Pull the release cord down and back towards the motor with a small amount of force. You will feel it disengage, and you will also see a small spring on the lever open up.
If your door opener is hard-wired to your garage, you must turn off the corresponding breakers or fuses to cut the power. Now, your door can be manually raised or lowered.
To re-engage the opener, push the wall console button to start the motor. Allow it to travel until you see the 'Inner Trolley' mechanism at the bottom of the rail. Locate the piece that slides along the bottom of the opener rail, as the opener chain or screw is turning. This piece needs to be re-engaged to the carriage, trolley, or other mechanisms that attach the arm to the opener rail. On some models, the door will reconnect automatically when the motor stops. For others, you will need to pull down on the red emergency release cord until you hear a click.

Remove bolts, brackets, and rollers
To remove bolts, brackets, and rollers from an electric roller garage door, you must first disconnect and unplug the electric garage door opener. Pull the opener's release rope and unplug the opener from its outlet. If the door opener is hard-wired to your garage, turn off the corresponding breakers or fuses to cut the power.
Next, unwind the torsion springs with steel winding bars. Place one winding bar into the hole in the spring's adjustment collar, then carefully loosen the set screw with a screwdriver while holding the winding bar in position. Take note of how many quarter turns you make to loosen the spring, as you'll need to twist it back to its original tension after replacing the rollers.
Now you can begin to remove the bolts, brackets, and rollers. Remove one door hinge and roller at a time, starting with the set of hinges second from the bottom. Remove all the screws holding the hinge in place, then lift the hinge off the door and manoeuvre the roller out of the door track. Use pliers or a hammer to pop the roller head out of the tracks if necessary.
Once all the rollers are removed, you can then remove the bolts and brackets. For the bolts, you will need to remove the two or three bolts on each side that secure the endplates to the vertical angle. Raise the forks as needed to free the bolts. Finally, remove the two long vertical angles from the jambs.

Realign the sensor eyes
Realigning the sensor eyes of an electric roller garage door is a simple task that can be completed in a few steps. Firstly, close the garage door to prevent any movement during the process. Then, turn off the power to the garage door for safety reasons. It is also advisable to wear electricity-resistant gloves when working with electrical components.
Once the power is off, locate the sensor mounting brackets and loosen the screws connecting them to the sensors. It is important not to completely remove the screws, only loosen them enough to allow for adjustments. The sensors should be positioned at the same level, approximately 6 inches from the ground, to ensure they effectively detect objects above and below them.
To realign the sensors, tie a string between the two sensor brackets and use a level to assess their alignment. Adjust the sensors as needed until they are properly levelled and aligned with each other. This can be done by moving the sensors up or down slightly until the string is level. The sensors should be pointed directly at each other, ensuring the "lasers meet up and the eyes from the sensors are making a connection".
After the sensors are aligned, tighten the screws to secure the sensors in place. Finally, restore power to the garage door and test the sensors to ensure they are functioning correctly.
