Why Won’t My Garage Door Open? 7 Common Causes & Fixes for Jacksonville Homes
Is your garage door stuck and refusing to open? Don’t panic — it’s a common issue that many homeowners in Jacksonville face. In this post, we’ll cover 7 of the most common reasons your garage door won’t open, what you can do to fix them, and when it’s time to call the experts at Fast Pro Garage Doors.
Broken or Worn-Out Springs
Your garage door springs are responsible for lifting the heavy weight of the door. Over time, they can snap or wear out, making it impossible to open the door — even manually.
Signs:
- Loud “bang” from the garage
- Door feels very heavy
- Door only lifts a few inches
- What to do:
🛑 Do not attempt to fix springs yourself — they are under extreme tension.
📞 Call Fast Pro Garage Doors Jacksonville at (904) 549-7804 for professional spring replacement.
Dead Batteries or Remote Issues
Sometimes the problem is as simple as a dead battery in your remote or wall switch.
Quick Fixes:
- Replace batteries in remotes
- Try the wall button
- Reprogram your opener if necessary
If none of these work, it could be an opener or wiring issue.
Misaligned or Dirty Safety Sensors
Garage doors have safety sensors near the ground on both sides of the opening. If they’re dirty or misaligned, the door won’t close or open properly.
Fix It Yourself:
- Wipe the sensor lenses with a cloth
- Make sure both sensors are aligned and lights are solid

Bent Tracks or Off-Track Rollers
If the metal tracks guiding your garage door are bent, warped, or blocked, the door will jam halfway or not move at all.
What You Can Do:
- Clear any debris from the tracks
- Check for obvious bends or damage
⚠️ Don’t force the door — this could cause more damage. Let a pro fix alignment safely.
Faulty Garage Door Opener
Garage door openers can fail due to old wiring, broken circuit boards, or limit switch malfunctions.
Check:
- Is the opener plugged in?
- Are the lights on?
- Does it make noise but not move the door?
If so, it may be time to replace your opener. Fast Pro Garage Doors offers opener installation and repair across Jacksonville.
Manual Release Cord Pulled
If someone pulled the red emergency cord, the garage door will disconnect from the opener and operate manually — or not at all.
Fix:
- Reattach the door to the opener by pulling the cord and running the opener again
Not sure how? Give us a call — we’ll walk you through it or come by to reconnect it.
Sensor or Opener Wiring Issues
Damaged or loose wiring can prevent the opener or sensors from working properly.
DIY Tip:
- Check for frayed wires, chew marks, or loose connections
Never handle exposed wires — call a licensed tech to stay safe.
Should You Try to Fix It Yourself?
DIY is okay for:
- Replacing remote batteries
- Cleaning and aligning sensors
- Resetting the opener or power
🛠️ Call the pros if:
- The door is heavy or jammed
- You suspect spring, track, or wiring issues
- You tried everything and it still won’t open
