Common Causes of Garage Door Opener Issues

Common Causes of Garage Door Opener Issues

Your garage door opener is the heart of your garage door system. The operator motor is the part of the system that drives the springs and cables to open and close your garage door. When it stops working, it can throw off your whole day. Before you panic or rush to call a professional, let’s explore some typical issues and fixes that might save you time and money.

Misaligned or Blocked Sensors

If you push the button and the garage door begins to open and then completely reverses direction, chances are you have either misaligned or blocked safety sensors.

What are Safety Sensors?

Garage door openers come with safety sensors installed near the base of the door tracks on both sides. These sensors prevent the door from closing if something or someone is in the way.

Common Sensor Issues

Even the smallest of objects, like a spider web right between the sensors can cause issues! Make sure there’s no debris, leaves, or cobwebs blocking your sensors. Also, check if they are aligned; sometimes, a simple nudge can knock them out of alignment.

Control Malfunctions

Remote Battery Problems

The most common issue is dead batteries. Always check your remote’s batteries first. It’s a simple fix but often overlooked.

Signal Interference

Another issue could be signal interference. If you’ve replaced the batteries and the door still won’t budge, consider whether something new in your home might be interfering with the signal. Once, a customer had placed a new LED light in the garage, not realizing that certain types of LEDs can emit a frequency that disrupts the opener’s signal.

Wall Switch Doesn’t Work

Unscrew the switch from the wall and touch the two wires together. These are low voltage wires so they will not shock you. If the opener runs, you have a bad switch. Purchase the one recommended for your model and replace the switch. If the opener doesn’t run when you touch the wires at the opener, use a small wire and jump those same two wires at the opener terminal. If the opener runs, the wire that connects the opener to the switch is bad. You can replace it using 18- to 22-gauge wire.

Worn Out Gears or Motor


Some gears can wear out inside your opener over time, especially in chain-driven models. If your opener sounds like it’s working but the door isn’t moving, worn gears might be the culprit.

Motor Issues

Motor burnout is another common issue, particularly in older units or in homes where the garage door sees a lot of use. Regular maintenance can extend the life of your motor, so don’t skip on those service calls.

Misadjusted Settings

Limit Settings

Garage door openers have limit settings that control how far the door should move before it’s fully open or closed. If these aren’t set correctly, your door might stop short or refuse to close completely. I had a call where adjusting the limit settings was all it took to fix a door that wouldn’t close all the way.

Force Settings

Similarly, the force setting determines how much force the door uses to open and close. If this is too low, the door might not open at all; if it’s too high, it could damage the door or become a safety hazard.

Track and Roller Issues

Track Misalignment

A misaligned track can cause a lot of issues. If your door is noisy or shaky, check the tracks for any bends or gaps between the rollers and the track.

Dirty or Worn Rollers

Rollers can get dirty or wear out, causing the door to operate inefficiently. I’ve seen doors improve dramatically just with some cleaning and a little lubrication.


Regular maintenance is key to extending the life of your garage door opener. Most garage door opener issues can be traced back to one of these common causes. While some fixes are easy DIY projects, others might require professional help for your opener repair. Keep those sensors clear, batteries fresh, and settings adjusted. Remember, if you’re ever in doubt, it’s safer to call a professional than to tackle a potentially dangerous repair yourself.
