Garage Door Won't Close? Check These 5 Things Before You Call a Tech

You hit the button, the door starts down, and then it stops and goes right back up. Or it doesn't move at all, and the opener light just blinks at you. It's one of the most common calls we get in Las Vegas, and a good number of them can be solved in a few minutes with no tools.

Here are five things to check before you pick up the phone.


1. Look at the safety sensors (photo eyes)

Every opener built in the last few decades has two small sensors mounted on either side of the door, close to the floor. They send an invisible beam across the opening. If something breaks that beam, the door is designed to stop and reverse so it never closes on a person, pet, or car.

The usual culprits:

  • Dirt or dust on the lenses. Las Vegas dust is relentless. Wipe both lenses with a soft, dry cloth.
  • Misalignment. If one sensor got bumped by a bike, trash can, or a stray foot, the beam no longer lines up. Most sensors have a small indicator light. If one is off or blinking, it's not seeing the other.
  • Sunlight. Low morning or evening sun shining straight into a lens can confuse it. Shading the sensor or repositioning it slightly can help.

If the lights on both sensors are solid after cleaning and aligning, try the door again.


2. Check for anything blocking the path

It sounds obvious, but a small item on the floor, a stuck bit of weather seal, or something leaning against the door can trigger the reverse function. Do a quick visual sweep of the full opening.


3. Try the wall button instead of the remote

If the wall button works but the remote doesn't, the problem is almost certainly dead batteries or a remote that needs to be reprogrammed. If neither works, the issue is likely the opener itself, or power to it. Check that the opener is plugged in and that the outlet (and its breaker) has power.


4. Look for the "lock" setting on the wall panel

Many wall panels have a lock or vacation button. If it was pressed accidentally, the opener ignores remotes. Check the panel for a lock indicator and toggle it off.


5. Do the manual test

Pull the red emergency release cord with the door fully closed and lift the door by hand. A healthy, balanced door should lift smoothly and stay roughly halfway up when you let go.

  • If it feels extremely heavy, or slams down when you release it, stop. That points to a broken or weak spring, and this is not a DIY fix. Springs hold a dangerous amount of stored energy.
  • If it moves smoothly but still won't close with the opener, the issue is likely with the opener's travel limits, force settings, or logic board.


When to call a professional

Call us if you see any of the following:

  • Frayed, loose, or off-track cables
  • A gap in the spring, or a door that feels heavy or uneven
  • Bent or damaged tracks
  • Grinding, popping, or burning smells from the opener
  • The opener hums but doesn't move the door

These are safety issues. Trying to fix them yourself can lead to serious injury, and a small problem can turn into an expensive one fast.
