Your garage door won't open — it's one of the most frustrating household problems, especially when you're in a hurry. Here are the most common causes and what you can do about them.
1. Dead Remote Batteries
The simplest fix. Replace the batteries in your remote control. If you have a wall-mounted keypad, try that to see if the opener still works.
2. Broken Spring
This is the most common mechanical cause. If the door is extremely heavy to lift manually, or if you heard a loud bang, a spring has likely broken. Do not attempt to operate the door — call a professional.
3. Safety Sensor Issues
Modern openers have photo-eye sensors at the bottom of the door tracks. If they're misaligned, dirty, or obstructed, the door won't close (though it should still open). Check for obvious obstructions and clean the sensor lenses.
4. Track Misalignment
If the tracks are bent or misaligned, the door may get stuck partway. Look for visible bends, gaps between the track and the rail, or debris in the tracks.
5. Broken Cable
Cables work with the springs to lift the door. A broken cable can cause the door to hang at an angle or not move at all. This requires professional repair.
6. Opener Motor Failure
If you hear the motor running but the door doesn't move, the motor or its gears may have failed. This is common in older openers.
7. Power Outage or Electrical Issue
Check if the opener is plugged in and that the outlet has power. Try the manual release to operate the door manually until power is restored.
