Here's what most homeowners don't realize about garage door repair: half the time your door isn't actually broken. It's just stuck, unpowered, or blocked by something simple you can fix yourself in five minutes. Before you call for same-day service, run through these troubleshooting steps to avoid an unnecessary repair bill.
Your garage door won't open for one of three reasons: power loss, obstruction, or mechanical failure. The fastest way to narrow it down is to check the simple stuff first.
Is the door plugged in? Sounds silly, but circuit breakers trip. Check your garage electrical panel and flip the breaker back on if it's off. Try the wall button or remote again. If nothing happens, move to the next step.
Look at the photo eye sensors near the bottom of the door frame on both sides. These infrared sensors prevent the door from closing on people or objects. If one is blocked by dust, a spider web, or knocked out of alignment, the door won't respond. Wipe them clean with a dry cloth. Make sure both sensors have a clear line of sight to each other. If one is pointed at the wall instead of across to its partner, gently adjust it back into position.
A broken spring, snapped cable, or stuck track will keep your door locked in place. But before you assume you need a professional, look for the obvious culprits.
Walk around your garage and scan the entire track on both sides from top to bottom. Is there a fallen tool, stored item, or debris wedged in the track? Move it out. Even a small rock or buildup of dirt can prevent smooth movement. Wipe the tracks clean with a rag.
Grab the door itself (with the opener unplugged) and try to lift it manually from about waist height. A properly balanced door should rise smoothly with minimal force. If it feels heavy, stuck, or won't budge at all, you likely have a spring or cable issue that needs professional attention.
Sometimes the problem isn't your door. It's your opener.
Replace the batteries in your remote. Seriously. Dead batteries cause 15% of "my garage door won't open" calls. Try the wall button inside your garage instead. If the wall button works but the remote doesn't, buy new batteries. If neither works, the opener motor itself may be the issue.
Stand in front of your door and press the wall button. Watch the light on the opener unit. Does it flicker? If the light comes on but the door doesn't move, the motor is running but the door is stuck or the cables are broken. If there's no light at all, check that power cord and circuit breaker again.

If you've done all this and your garage door still won't open, it's time for expert help. Broken springs and cables are not DIY fixes. They're under extreme tension and can cause serious injury if mishandled. A single spring typically lasts 7 to 9 years before it needs replacement, and when one goes, the other usually follows within months.

Why is my garage door stuck but the opener is running? If the motor engages but the door doesn't move, you likely have a broken spring, snapped cable, or track obstruction. Broken springs are the most common culprit. Do not force the door open, as this can cause further damage.
Can I fix a bent garage door track myself? Minor dents sometimes clear with a rubber mallet and wooden block, but severe bends require professional straightening or replacement. Misaligned tracks affect door safety and can strain the opener motor.
How often should I test my garage door photo eyes? Test them monthly by waving your hand in front of each sensor while the door is closing. It should reverse immediately. Clean them every three months, especially in dusty garages.
What does it mean if my remote works from 10 feet away but not from across the garage? Your remote batteries are likely dying. Replace them first. If a new set still has limited range, the receiver in the opener may need repair or the antenna could be damaged.
Is it safe to manually open a garage door with a broken spring? No. A broken spring means the door is very heavy and can drop suddenly, causing injury or property damage. Call a professional to handle it safely.
