We arrived at a rental property and tried to open garage door to get our vehicle in so we could unload luggage, etc. Could not open from outside. Went into house and, from inside garage, tried automatic opener but this did not work. So in trying to open the door manually, I reached up and pulled on the red cord attached to a lever. What I could not see, and was not expecting, is that the rope was frayed through almost completely. The rope broke when I applied some weight to it, sending me backwards onto the floor of the garage. https://www.youtube.com/e/Z_eZc-kh40c?app=desktop
4.4 Take the spring on the left and place it at the left end of the door as pictured here. Notice that the end of the wire points to the right toward the center of the door. This is a right wind torsion spring. It will go above the garage door on the left side of the spring anchor bracket. The winding cone at the other end of this spring is usually painted red.
