You must have a robust helper or two for a few of the steps.
Disconnect the Garage Door Opener
To remove an electrical garage door opener, first, close the garage door all the way, then unplug the motor unit from the wall socket. Pull the discharge cord hanging down from the opener track to disengage the opener’s trolley. Disconnect the trolley support arm from the door by removing the cotter and connecting bolt at the door end of the arm. The door is now separated from the opener, and you’ll remove the whole opener assembly, if desired, following the manufacturer’s instructions.
Remove the Garage Door Springs
Garage doors use springs to hold much of the load of the door during lifting and lowering. There are two sorts of spring mechanisms. Extension springs are located above the upper tracks on each side of the door. Torsion springs are attached to the header directly above the closed door. Torsion springs are always under tension and may be very dangerous to figure with if you do not know what you’re doing. If you’ve got torsion springs, call a garage door professional to possess the springs unwound safely.
To remove extension springs, open the garage door all the way and fasten C-clamps or pliers to the tracks on each side to stop the door from rolling down once the springs are removed. this is often important: Garage doors (even thin metal doors) are very heavy and may come down with great force without the springs carrying the majority of their weight.
Temporarily tape or tie each spring to a door track. Use pliers to get rid of the lift cable from the rock bottom bracket on all sides of the door. Disassemble the spring and pulley assemblies.
Lower the Door
Set blocks of wood on the ground where the door meets the ground. The blocks will prevent you from pinching your fingers once you lower the door. With one or two helpers supporting the load of the door within the open position, remove the clamps from the door tracks. Carefully lower the door until it rests on the woodblocks.
Warning
The door may weigh several hundred pounds. confirm you and your helpers can safely carry the load of the door while lowering it.
Remove the Door Panels
You will remove the door panels one at a time, performing from top to bottom. Start by removing the bolts securing the hinges to the highest door panel, employing a wrench. a typical 16-foot door has two roller hinges (one at each end of the panel) and three regular hinges in between. Remove the bolts only on the highest half each hinge, leaving rock bottom halves attached to the lower door panel.
With a helper or two supporting the highest of the highest panel, remove the roller bracket at each end of the panel. Carefully tilt the panel back and lift it far away from the tracks and therefore the remainder of the door. Set the panel aside.
Repeat an equivalent process to get rid of the remaining door panels. If desired, remove the door tracks by unbolting the sections one at a time. The vertical track sections are going to be fastened to the wall with lag bolts; remove these with a wrench.
