Why Your Garage Door Won’t Open (And When to Call a Professional in San Francisco)

Garage doors are one of the most frequently used entry points in modern homes. When they stop working unexpectedly, it can disrupt your entire day. For homeowners in San Francisco, garage door problems can happen due to daily wear, weather conditions, or mechanical failure.
Understanding the most common causes can help you identify when a quick fix is possible and when it’s time to call a professional garage door repair technician.
Common Reasons a Garage Door Stops Working
Broken Garage Door Springs
Garage door springs are responsible for supporting the weight of the door when it opens and closes. Over time, these springs weaken and eventually snap.
Signs of a broken spring include:
• Loud snapping sound from the garage
• Door opens partially then stops
• Door feels extremely heavy when lifting manually
Because springs are under high tension, repairing them without professional tools can be dangerous.
Garage Door Opener Malfunction
Sometimes the problem is not the door itself but the opener system. Faulty wiring, worn gears, or outdated motors can cause the opener to stop functioning.
Common signs include:
• The motor runs but the door does not move
• The opener remote stops responding
• The wall switch works but remotes do not
Replacing or repairing the opener often restores normal operation quickly.
Misaligned Garage Door Sensors
Modern garage doors include safety sensors that prevent the door from closing when something is in its path.
If these sensors become misaligned or dirty, the door may refuse to close.
Symptoms include:
• Door starts closing then reverses
• Blinking sensor lights
• Door only closes when holding the wall button
Cleaning or adjusting the sensors often solves the issue.
Worn Rollers or Tracks
Over time, rollers can wear out and tracks may become bent. This causes the door to move unevenly or get stuck midway.
Signs include:
• Grinding or scraping noises
• Door shaking while opening
• Door moving slowly or unevenly
Professional adjustment or replacement prevents further damage.
Why Professional Repair Is Important
Garage doors can weigh 200–400 pounds, and many parts operate under high tension. Attempting DIY repairs can lead to injury or cause additional damage to the door system.
Professional technicians have the proper tools and training to safely repair springs, cables, and opener systems.
