It is important to know the important components of a garage door. Otherwise, you won't be able to troubleshoot minor problems with individual parts before they render the whole door immobile.
Garage Door Opener
The opener powers the motor to lift the door open and close it. It is important to take note of the horsepower that a motor has. The more the horsepower, the higher the capacity it has to handle a door in relation to its weight.
There are three types of drive openers. A chain drive has a length of metal that goes around a metal rod that comes out of the motor. The chain is connected to an arm on the door that pulls it up to open and lets it down to close the door. A belt drive works the same way except that the belt is made of rubber. There is also a screw drive that opens and shuts the door via a threaded steel rod.
Garage Door Capacitors and Gears
The opener has two other parts you know about. There are capacitors and gears. Capacitors power the motor. Gears enable the movement of the drivers be it a chain, belt or screw drive. The turning motion of the gears moves the drives to open or close a garage door.
Garage Door Springs
Another important part of a garage door is the torsion springs. They steady the door as it opens and closes. Without them, the momentum of the door opening and closing would damage it. The springs counterweight this force with a force that is equal to the weight of the garage door.
A door may have torsion springs which are put inside or around the metal shafts above the door. It may also have extension springs that are placed along the sides of a door or above its horizontal tracks.
Garage Door Cables and Pulleys
Cables also have the important function of helping to lift up the door so that it can be pulled back by the drive. Pulleys guide the cables and provide precision and extra leverage for the door to be opened and closed. There are also rollers that keep cables on their path and sensors that stop the door in case an object is in the path of the door.
