Mounted on support brackets on the garage ceiling, a garage door opener is a motorized unit that operates the panel. If the device is damaged, the door could move slowly or fail to close completely—making it easier for intruders to break in. So you can explain any issues to a repair specialist, below is an overview of how it works and what safeguards in place to prevent dangerous accidents.   

How Garage Door Openers Function

A garage door opener is a radio that contains a motor. The opener remote acts as a radio transmitter. When it’s pressed, a signal is sent to the opener. Once the signal is received, the motor turns on. This prompts a trolley to move a drive assembly that opens or closes the door.

Due to the low cost, many homeowners install chain-drive garage door openers, where a metal chain is used to operate the trolley. As chain-drive systems can create a lot of noise, belt-drive openers are also popular. A rubber belt moves along the trolley for quieter operation. Screw-drive systems use threaded steel rods to move trolleys. With a direct-drive unit, the opener functions like a chain, belt, or rod. 

Industry Standards for Safe Operation

If the garage door opener is faulty, the panel could move unexpectedly. If the reverse function doesn’t work, someone could get seriously injured. That’s why the Consumer Product Safety Commission has standard requirements to prevent accidents.

Residential garage door openers must have functioning reverse mechanisms that can change door direction in two seconds, connections for additional safety devices, backup clocks if reverse mechanisms fail, and emergency release handles.
