6 Reasons Your Garage Door Won’t Close (And How to Fix Them)

1. Misaligned or Dirty Safety Sensors

Symptoms:

• The door reverses immediately after touching the floor
• No lights on sensors (or one is blinking)

How to Fix:

1. Locate the sensors (small boxes near the floor on both sides)
2. Clean the lenses with a soft cloth
3. Check alignment – Both sensors must face each other directly
4. Test the Door – If it still doesn’t close, try bypassing the sensors temporarily (not recommended long-term)

Pro Tip: Jacksonville’s humidity can cause sensor condensation—wipe them down monthly.

2. Obstructions in the Tracks

Symptoms:

• The door starts closing but stops suddenly
• Grinding or scraping noises

How to Fix:

1. Inspect the tracks for leaves, dirt, or debris
2. Remove any obstructions (wear gloves)
3. Check for dents or bends – If found, call a Jacksonville garage door repair pro

3. Broken or Loose Springs

Symptoms:

• The door is hefty to lift manually
• Loud “bang” noise before the door stopped working

What to Do:

• Do NOT attempt DIY spring repair (highly dangerous)
• Call a professional immediately

4. Limit Switch Needs Adjustment

Symptoms:

• The door closes partway, then reverses
• No other obvious issues

How to Fix:

1. Locate the limit adjustment screws on your opener
2. Turn the “close” screw slightly clockwise
3. Test the door after each minor adjustment

5. Disconnected Emergency Release Cord

Symptoms:

• The door won’t respond to any commands
• The emergency release handle is hanging down

How to Fix:

1. Pull the door down manually
2. Push the emergency release handle back toward the opener until it clicks
3. Try operating the door normally

6. Power or Remote Issues

Symptoms:

• The door doesn’t respond to the wall button or remote
• The opener lights are off

How to Fix:

✅ Check the power outlet

✅ Replace remote batteries

✅ Reset the opener (unplug for 30 seconds)

Jacksonville-Specific Factors That Affect Garage Doors

Humidity & Salt Air Problems

• Causes rust in tracks and rollers
• Leads to sticky door operation

Prevention Tip: Apply silicone lubricant monthly

Frequent Storms

• Power surges can damage openers
• High winds may knock doors off-track

Preparation Tip: Install a battery backup for your opener

When to Call a Professional in Jacksonville

While many issues are DIY-fixable, call LNU Garage Door FL immediately if:

✔ Cables are frayed or loose
