A garage door opener is a modern convenience that most homeowners take for granted—until it stops working. When your opener malfunctions, it can leave you stuck inside or locked out, disrupt your schedule, and compromise your home’s security.
This guide will help you understand common garage door opener problems basic troubleshooting steps you can take, and when to call a professional garage door opener repair service.
How Garage Door Openers Work
A garage door opener is made up of several components that work together to lift and lower the door:
-
Motor unit – Powers the lifting mechanism.
-
Drive system – Chain, belt, or screw drive that moves the door.
-
Safety sensors – Detect obstructions and prevent the door from closing.
-
Remote controls & wall switch – Allow you to operate the door.
-
Limit settings – Control how far the door travels.
If any of these parts fail, the opener may not work properly.
