Most homeowners don't think about their garage door until it stops working. One morning you hit the button, nothing happens, and suddenly you're stuck. Before you panic or spend money on an unnecessary service call, let's walk through what's actually broken and what you can safely troubleshoot yourself.
Your door won't open. That's the symptom. The cause could be one of five things. The opener motor isn't engaging. The springs are broken. The door is stuck on its tracks. The remote battery is dead. Or the safety sensors are misaligned. I've rolled out to calls in Coronado for fifteen years, and nine times out of ten, it's one of these five. See our guide on commercial garage doors in coronado: repair costs and heavy-duty solutions.
First, check the obvious stuff. Is the remote battery dead? Replace it and try again. Can you hear the opener motor running when you press the button? If it's silent, the opener itself might be the problem. If it's grinding or humming without the door moving, the springs are likely broken. Springs last about 7 to 9 years under normal use, not 10 or 11, so if your door's that old, don't be surprised.
Look at the tracks on both sides of the door. Is anything blocking them? Debris, leaves, or rust can stop the door cold. Clear the tracks carefully. Sometimes the door is just stuck from sitting in one position too long, especially in our coastal salt air here in Coronado and across San Diego County.

If your door opens partway and stops, or won't open at all despite the motor running, your torsion springs are broken. These aren't something to fix yourself. I mean it. Springs are under extreme tension, and a slip costs fingers or worse. A broken spring costs between $200 and $400 for parts and labor when caught early. Ignoring it and running the opener anyway can damage the motor and gearbox, pushing your total repair bill to $800 or more.

Most modern openers have safety sensors near the floor on both sides of the door. These infrared sensors prevent the door from closing if something is in the way. If they're dirty, misaligned, or disconnected, the door won't close or will reverse mid-close. Clean the sensor lenses with a soft cloth. If that doesn't work, the sensors need realignment, which is a quick job for a professional.
Track misalignment happens when the door shifts slightly and the rollers don't sit properly. The door feels stuck or grinds when moving. This is fixable but requires proper tools and knowledge. Forcing a misaligned door can bend the track permanently, making the repair more expensive.

Why won't my garage door open even though the motor is running? Your torsion springs are likely broken. Springs support the door's weight; without them, the motor can't lift it. This is a job for a professional. Never attempt to replace springs yourself due to the extreme tension involved.

How often should I maintain my garage door? Inspect and lubricate your door annually. This catches worn springs, misaligned tracks, and sensor issues early. Regular maintenance extends your door's life by years and prevents costly emergency repairs.
What's the difference between a stuck door and a broken door? A stuck door is usually debris, misalignment, or a dead battery. A broken door has damaged springs, a failed opener, or a bent track. Stuck doors are often fixable yourself; broken doors need a technician.
