Garage Door Opener Not Working: What to Check
Garage Door Opener Not Responding
When your garage door opener stops working, it's frustrating — but the fix is often simpler than you think. Before calling for repair, there are several things you can check yourself.
Start with the basics: Is the opener plugged in? Has a circuit breaker tripped? Is the remote battery dead? These simple checks solve the problem more often than you'd expect.
Troubleshooting Steps
First, try the wall button. If the wall button works but the remote doesn't, the issue is with the remote — try replacing the battery or reprogramming it. If neither the wall button nor the remote works, check the power supply to the opener unit.
If the motor runs but the door doesn't move, the drive gear or sprocket may be stripped. You'll hear the motor humming without any door movement. If the door starts to open but reverses, check the safety sensors and the force adjustment settings.
When DIY Won't Fix It
If you've checked the power, batteries, sensors, and the door still won't respond, the issue is likely internal to the opener — a failed circuit board, burned-out motor, or stripped gear. These repairs require professional tools and knowledge.
If your opener is more than 15 years old, replacement may be more cost-effective than repair. Modern openers are quieter, more secure, and offer smart home features that older units lack.
