A working garage door is something most homeowners take for granted—until the day it suddenly won’t open or close. The truth is, garage doors can fail without much warning, leaving you stuck inside, locked out, or facing an urgent safety issue. That’s why it helps to understand what causes these unexpected breakdowns and when to call for emergency garage door repair.

Here are the most common reasons garage doors stop working out of the blue:

Broken Torsion or Extension Springs

The springs on your garage door do most of the heavy lifting. Over time, they wear down with repeated use. When they break, the door won’t lift at all—or it might crash down unexpectedly. This is one of the leading causes of emergency calls and should always be handled by a professional. Attempting to replace springs without proper tools or experience is dangerous.

Malfunctioning Garage Door Opener

Sometimes the door itself is fine, but the opener motor stops responding. It might hum but not move, or fail to activate at all. This can happen due to ...
... worn gears, fried circuits, or electrical issues. If resetting or replacing the batteries in your remote doesn’t help, it’s time to check the opener unit or call for support.

Snapped Cables

Garage door cables are under high tension and work with the springs to move the door smoothly. When one snaps, the door can become unbalanced, crooked, or jammed. You may hear a loud bang when the cable breaks. If you notice fraying or sagging, don’t wait for it to fail completely.

Misaligned or Bent Tracks

If your garage door moves unevenly or gets stuck halfway, a track alignment issue could be the reason. Debris, dents, or loose brackets can block the rollers, stopping the door mid-cycle. Ignoring this can cause further damage to the rollers or opener.

Sensor Issues

Modern garage doors come with safety sensors to prevent accidental closure when something is in the way. If these sensors are misaligned or dirty, your door may refuse to close. It might go down slightly, then reverse back up. Cleaning the sensor lenses or checking alignment often solves the problem—if not, there may be an electrical fault.

Weather and Temperature Changes

Extreme cold or heat can affect how garage door components work. Lubricants may thicken, metal parts can contract or expand, and electronics might fail during power surges. Seasonal changes often trigger emergency breakdowns.
