If you’ve not shopped for a garage door opener before, you may not realize there are several options on the market. The most common door opener in the U.S. is the central system. You’ll recognize it by the motor installed on the garage ceiling. If your garage has a cathedral height ceiling, you likely have a jackshaft opener installed on the side of the garage door.
Your Magical Remote
You already know how convenient life is with the garage door opener remote in your hand. Ever wondered how it works? Your remote has a radio transmitter that sends out a signal to the receiver on the garage door opener. You press the button, the radio signal goes to the opener, and magic happens. When it doesn’t, the garage door technician gets a call. Dead batteries in the remote are the reason for a significant number of garage door service calls.
How the Door Opens and Closes
The remote only plays a small but essential role in getting the garage door opened and closed. The real star is the drive. If you have an older system or an unattached garage, you likely have a chain drive. It’s a bit like a bicycle chain, but noisier. The metal chain drives the trolley. By the way, the trolley, or the carriage, is the rail that stretches across the garage ceiling. Many newer systems use the quieter belt drive. Instead of a chain, a rubber belt drives the trolley. Belt drives have fewer mechanical parts, so they need less frequent maintenance. To make things more fun, you can also use a screw driver or a direct drive. If you’re not sure which drive your garage door opener uses, ask your garage door repair technician at your next routine maintenance appointment.
If you’ve ever watched your garage door stop and go in the opposite direction, you’ve witnessed an essential safety feature. It’s a law in the U.S. that any garage door opener sold on the market today must have two automatic reversal systems. One is mechanical. If the system encounters an obstacle while the door closes, it reverses the door. All openers also have an electronic reversal system, which uses sensors or photo eyes mounted on each side of the garage door. The sensors sit six inches from the ground and project a laser beam. If anything breaks the connection, the door reverses.
