If you've ever dealt with a stuck garage door, you know how frustrating it can be. One minute your door closes normally, the next it won't budge. Before you panic or call for service, there are several troubleshooting steps you can try yourself. Many stuck doors are caused by simple issues that take just a few minutes to fix, saving you time and money.
Start with the simplest culprits. Is the garage door opener receiving power? Look at the motor unit mounted on your ceiling. The outlet it's plugged into may have tripped, or the breaker in your panel could be off. Flip the breaker back on and try opening the door again.
Next, check the remote battery. A dead battery is the number-one reason homeowners think their door is broken when it's really just a power issue. Replace it with a fresh one and test. If you have a keypad, try using that instead. If the keypad works but the remote doesn't, you've found your problem.
Make sure nothing is blocking the door's path. Even a small object can trigger the safety sensors near the bottom of the opening. Move boxes, tools, or debris away from the tracks. Leaves and dirt can accumulate in the sensor eyes, blocking the beam. Wipe both sensors clean with a soft cloth.
Now look at the physical door itself. Walk around to both sides and examine the horizontal tracks. Are they bent or dented? If the tracks are visibly damaged, the door won't slide smoothly. Bent tracks often require professional straightening.
Listen carefully when you try to open the door. A loud grinding noise, popping sound, or complete silence from the motor means something internal is wrong. Springs under tension are under incredible stress. If you hear a loud bang followed by the door not working, a spring may have broken. Do not attempt to repair or replace garage door springs yourself. They're dangerous and require special tools.

Your garage door has two sensors on either side, about six inches up from the ground. They create an invisible beam. If that beam is interrupted, the door won't close. This is a safety feature that prevents the door from closing on a person or pet.
Align both sensors so they face each other directly. You should see a small light on at least one sensor, indicating it's working. If both lights are off, check the wiring connections at the back of each sensor. Sometimes vibration loosens them. If lights are on but misaligned, loosen the mounting bracket slightly and adjust the sensor until both lights shine steadily.

If your door opens partway and then stops, the problem could be the torsion spring losing tension. Springs last about 7 to 9 years under normal use. As they age, they weaken. A weakened spring makes the opener work harder, and eventually the motor can't lift the full weight of the door.
Another possibility is a frozen track during cold Colma mornings. Metal contracts in cool temperatures. Apply a silicone-based lubricant to the tracks and hinges. Do not use WD-40 or regular oil, as these attract dirt and gum up the mechanism over time. Wipe away excess lubricant with a clean cloth.
If you've checked the power, remote battery, sensors, and tracks and the door still won't open, it's time to bring in a professional. Broken springs, damaged openers, and bent tracks require specialized equipment and expertise. Explore our repair services to see what we offer in your area.

Why won't my garage door open but the light on the opener blinks? A blinking light usually signals a safety sensor issue or a broken spring. Check that both sensors are aligned and clean. If they look fine, the spring may be broken and requires professional replacement.
Can I manually open a stuck garage door? Yes. Most openers have a red emergency handle inside the garage. Pull it to disengage the door from the motor so you can lift it by hand. This works if springs are intact, though a broken spring makes the door very heavy.
How much does it cost to fix a stuck garage door? Costs vary widely depending on the cause. A sensor cleaning is minimal, while a spring replacement is more expensive. Contact us for a specific estimate on your situation.
Is it safe to use my garage door if it's stuck sometimes? No. Intermittent problems usually signal a worsening issue. Use it only if necessary and contact a technician right away to prevent complete failure.
Why is my garage door stuck on cold mornings in Colma? Cold metal contracts and tracks can frost or freeze slightly. Lubricating tracks and allowing the garage to warm up often helps. If it persists, have a technician check the spring tension.
