Garage Door Won't Open? Troubleshooting Steps Before You Call
2026-06-11 7 min read
A customer called last Tuesday saying her garage door wouldn't open. She'd already checked the obvious stuff. Turns out, a broken sensor was throwing off the whole system. Before you panic or spend money on a service call, here are the actual troubleshooting steps that work. Some take two minutes. Others require a professional. Knowing the difference saves time and money.
Check the Power and Remote First
This sounds basic, but I'd estimate one in five "broken" doors just have a dead battery in the remote. Grab a fresh battery, try again. If the door still won't open, walk to the wall console inside your garage. Press the button there. Does the door move? If yes, you've got a remote issue, not a garage door repair emergency. If the wall button also does nothing, move to the next step.
Look at the garage door opener unit mounted to your ceiling. Is the light on? Can you hear any clicking or humming sounds when you press the button? No power at all means check your circuit breaker. A tripped breaker is an easy fix. Flip it back and test again.
Inspect the Photo Eye Sensors
Modern garage doors have safety sensors on both sides of the opening, usually about six inches from the ground. These photo eyes prevent the door from closing if something blocks the path. If one is misaligned or dirty, the door won't move at all. Walk around and look at both sensors. Are they facing each other? Wipe the lenses clean with a soft cloth. If either lens looks cracked, that's a problem we can handle quickly.
You can also test the sensors by placing a broom handle across the door opening while pressing the wall button. If the door tries to close and then reverses, your sensors are working. If nothing happens, a sensor might be broken and need replacement.
Look for an Obvious Obstruction
Check the entire track from top to bottom. Leaves, ice buildup, or a misplaced box can prevent smooth operation. Clear away anything blocking the path. In winter months around Tamworth and southern New Hampshire, ice accumulation is common. Gently remove it with a plastic scraper, not a metal one that could damage the track.
Also check if the door itself looks bent or twisted. Dents in the panels won't always stop the door, but serious damage to the frame or track can make it stick midway. If you see warping or deep dents, that's beyond a quick troubleshoot.
Test the Emergency Release
Every garage door opener has a red emergency release cord hanging from the motor unit. Pull it. This disconnects the opener and lets you manually move the door. Try lifting it gently. Does it move smoothly? If the door is extremely heavy or stuck, the problem might be with springs or cables, not the opener itself. Springs last 7 to 9 years on average, and when they fail, a garage door can feel like it weighs a thousand pounds.

Frequently Asked Questions
What does a garage door repair typically cost in Tamworth? Repair costs vary widely depending on what's broken. A sensor replacement might run $150 to $300. Spring replacement typically costs $250 to $500 per spring. Motor replacement runs $400 to $800. We provide a free estimate before any work begins, so you know the exact cost upfront.
Can I fix a broken garage door spring myself? No. Springs are under extreme tension and can cause serious injury if they snap during DIY repair. Always hire a professional for spring work. It's one of the most common garage door injuries we see, and it's completely preventable.
How long does a garage door repair usually take? Most repairs take between one to three hours. Sensor adjustments might take 30 minutes. Spring or cable replacement takes longer. We'll give you a timeframe when we arrive and assess the problem.
Why won't my garage door open even though the motor is running? If the motor hums but the door doesn't move, a broken spring, snapped cable, or derailed track is likely. These prevent the motor from lifting the door weight. Professional inspection is needed to diagnose which component failed.
Should I replace my garage door or repair it? If repairs cost more than 50 percent of a replacement, replacement usually makes financial sense. We'll help you weigh the options and recommend what's best for your situation and budget.
