A customer called last Tuesday with a stuck garage door that wouldn't budge. Before we quoted a service call, I walked him through three quick checks. Turns out, a misaligned sensor was the culprit, not a broken spring or motor. In this post, I'll share the same troubleshooting steps so you can figure out what's actually wrong with your garage door before paying for a repair visit.
When your garage door won't open or won't close all the way, the cause matters. A door that's stuck halfway isn't the same as one that won't respond to the remote. A door that moves slowly differs from one that jerks and stops.
Knowing the difference saves you money. If you can describe exactly what's happening, we can often diagnose the problem over the phone and bring the right tools on the first trip. That means lower labor costs and faster turnaround. So before you call, spend two minutes observing: Does the door move at all? Does the opener make noise? Is the door physically blocked?
Start with the remote and wall button.
Replace the batteries in your remote control. Seriously. Dead batteries cause 30% of "broken" garage doors we see in Universal City and the surrounding areas. Test with fresh batteries from a pack you know works.
Next, press the wall button directly. If that works but the remote doesn't, you've narrowed it down to a battery or signal issue, not the door itself. If neither works, move to the next step.
Look at the photo eye sensors on both sides of the door frame, about six inches up from the floor. These infrared sensors tell the opener when it's safe to close. If one is blocked, dirty, or misaligned, the door won't close. Wipe both lenses clean with a soft cloth. Make sure nothing is casting a shadow across them. Realign them so they face each other directly.

Open your garage. Watch and listen as you press the button.
Does the opener motor run but the door doesn't move? The problem is likely the cable, spring, or pulley system. These components bear the load. Springs last 7 to 9 years with normal use, and when they fail, the door becomes heavy and hard to lift. This is not a DIY repair. Garage door springs are under extreme tension and can cause serious injury.
Does the door move a little, then stop? Check for physical obstructions. Leaves, ice buildup, or debris in the tracks will cause the door to bind. Clear the tracks from top to bottom on both sides. Use a dry cloth first, then a vacuum if you have one.
Does the opener make noise but nothing happens? The gears or chain inside the motor head may be damaged. This requires professional service to diagnose properly.

What should I do if my garage door is stuck halfway? Stop trying to force it. Check for obstructions in the tracks first. If the door is heavy or won't budge, a spring or cable may be broken. Do not attempt to repair this yourself. Call a professional immediately.
Can I fix a misaligned photo eye sensor myself? Yes. Photo eye sensors are simple to realign. Wipe the lenses clean and angle them so they face each other directly without shadows. If the door still won't close after alignment, the sensor may be damaged and need replacement.
How much does garage door repair typically cost in Universal City? Repair costs range from $150 to $500 depending on the issue. A sensor replacement is cheaper than a spring replacement. We provide free estimates so you know the exact cost before we start work.
Why does my garage door opener run but the door doesn't move? The motor is running but the door isn't lifting. This usually means a broken spring, snapped cable, or pulley failure. These are safety-critical components that require professional repair.
Is it safe to use my garage door if it's stuck? No. Stop using it until you know what's wrong. A stuck door may have a broken spring or cable under tension. Using it could cause the door to fall or cause further damage.
