Hi, I would like to remove the electric motor from a garage door in the hopes that I can use it as a manual door.

I would like to be able to pull it up and down by hand (I will most likely add a handle).

I am hoping someone may know if this is possible?

I think the motor is at one end:

And the other is just a support:

There appears to be a manual hand crank:

In the future I may replace the door with something more practical.

I have an idea how it might be possible, but I think I would need to support the door and remove the brackets. Then take it down, and pull it apart. But I have no knowledge as to how the supporting axle is connected to the motor or if it is even possible to then move it manually.

Perhaps it would be too heavy to lift manually? Or perhaps there is an easier solution?

I am open to anyone’s advice.

    The one that came manual will have a huge coil of spring acting as a counter-weight, which helps you with the lifting. I’d assume the one with motor doesn’t have that, and completely rely on the motor to lift the door, so if you were to remove the motor, it will take huge amount of strength to lift, and it won’t hold position so it might slam down at you at any given time.

    So imo nope, it’s dangerous.

    Unless you are the Hulk, it is extremely unlikely you’ll be able to open this door with only a handle, like you would a conventional residential garage door.

    You can remove the motor, but you’d want to replace it with a manual chain hoist. You’ll want to research “commercial roll up door chain hoist”. I think they are mostly similar, but maybe not all exactly the same… So, make sure you get one that works with your door. There will likely be a bit of customization involved with the installation to get things lined up correctly.

    Obligatory, “don’t fuck with garage door motors!” The spring is under tension and people have died messing with them.

    Thank you everyone for your very useful comments 👍 Especially the warning about the motor!

    The property is in need of repair and was abandoned for a while; I am slowly trying to improve what I can without spending any money (if possible).

    The garage door was previously operated by a remote control; when it worked it was intermittent and there is no other exit; I was often worried someone could get trapped in there; especially if there was a power cut. I enquired about a crank, as there is a socket, but this would only work from the inside and the crank would be very slow to operate.

    Unfortunately the motor no longer works, I replaced the battery in the remote and tested to be sure. I don’t have the money to replace anything, and if I did, I would probably prefer to just buy a manual ‘tilting’ garage door type.

    At the moment the door is up/open, and has been for several years (the photo is old), I am currently using the garage to store wood for now.

    I don’t think the door is too heavy; I think it would be possible to lift it/modify it. The photos are not so clear but the metal is thin, probably aluminium. Although it would certainly require some effort to lift and would most likely slam down without some support.

    If it was safe to remove the motor and easy to lift/support I may have considered some modifications using what I have lying around. But I am thinking given the danger/cost/effort it may stay as it is for now until I have some money to replace it completely with a tilt door.

    Thank you all again for your advice, this is a great first experience here.
