The working mechanism of a garage opener is mainly driven by a power unit. The power unit has an electric motor which is attached to a track. A trolley is attached to the garage door via an arm which slides back and forth, thus opening and closing the garage door. When the motor is operating, the trolley pulls along a chain, screw or a belt. Suppose there is a power failure, in that case, the quick release mechanism will disconnect the garage door from the garage door opener. The entire mechanism of garage door opener is situated above the garage door. The power unit is located at the end of the garage and hangs from the ceiling.

Types of Garage Door Openers

Based on the mechanism of operation different types of garage door openers have come up in the market, they are:

  • Chain drive openers: They have a bicycle chain which connects trolley to the motor.
  • Belt drive openers: They have a belt instead of a chain
  • Screwdriver openers: They have a long screw which is connected to the trolley
  • Direct drive openers: They use a gear wheel to drive the trolley along a fixed chain
  • Jackshaft openers: They move the garage door up and down with the help of a motor that is attached to the side of a torsion rod which spins up and down. The main benefit of this type of garage opener is that it saves space from the ceiling but it needs a torsion rod installed with the door which is a drawback.

Remote controlled garage door opener has been here with us for a long time. The first generation had a transmitter and a receiver which controlled the opener mechanism. The transmitter will transmit a radio frequency and receiver will listen to that radio signal, thus opening and closing the garage door. But due to low power and limited range, the transmitter signal would be received by the nearby opener also. In the latest technology, a rolling code is employed to solve this problem. In this, a different code is sent from the previous one, thereby unlocking the door. Transmitter sends the ‘next’ code in sequence .receiver compare ‘next’ code to its calculated ‘next’ code.

Lately, there has been a rise in incidents of cloning of garage door openers. It has been due to the fact that most garage door openers use fixed–code encoding techniques. This can be cloned easily with a remote-controlled duplicator (copy remote).
