Many DMV homeowners ask, why won’t my garage door close all the way anymore? This frustrating problem usually points to a sensor, track, or spring issue. Garage Door Services DMV, a subsidiary of Brickfront Properties and Construction, repairs this exact issue every week. Our technicians identify the root cause and restore safe, full closure quickly.
What Causes a Garage Door to Stop Before Closing?
Several common issues stop a garage door short of the floor. Understanding these causes helps you decide if you need a professional or a quick fix.
- Dirty or misaligned photo-eye sensors: Sensors near the floor detect obstacles and reverse the door if blocked or dusty.
- Bent or damaged tracks: A warped track prevents the rollers from guiding the door smoothly downward.
- Broken springs: Weak or snapped springs cause the opener to struggle and stop mid-cycle.
- Incorrect limit settings: The opener’s limit switch tells the door when to stop, and wrong settings cause early stopping.
- Debris on the track or floor: Small objects or buildup block the door’s path and trigger a safety reversal.
How Do I Fix a Garage Door That Won’t Close All the Way?
You can troubleshoot several issues yourself before calling a technician. Start with the simplest checks first.
- Clean the sensor lenses: Wipe both photo-eye sensors with a soft cloth to remove dust or cobwebs.
- Check sensor alignment: Confirm both sensor lights glow steady, not blinking, to ensure proper alignment.
- Inspect the tracks: Look for dents, gaps, or debris along both vertical and horizontal tracks.
- Test the limit switch: Adjust the opener’s down-limit dial slightly if the door stops too early.
- Listen for grinding noises: Unusual sounds often signal spring or roller damage that needs professional attention.

Is a Garage Door Safety Sensor Issue Dangerous?
Safety sensors exist to prevent injuries and property damage. The Consumer Product Safety Commission tracks garage door incidents nationwide, and sensor failures rank among common causes.
- Federal safety standard: Openers manufactured after 1993 must include working auto-reverse sensors by law.
- Injury prevention: Functioning sensors stop the door from closing on children, pets, or vehicles.
- Liability risk: A malfunctioning sensor increases your risk of accidents and potential legal exposure.

When Should I Call a Professional for Garage Door Repair?
Some closing issues require specialized tools and training. DIY attempts on springs or cables can cause serious injury.
- Spring replacement: High-tension springs need professional handling to avoid snapping injuries.
- Cable or pulley damage: Frayed cables signal an unsafe door that needs immediate expert repair.
- Opener circuit board failure: Electrical issues inside the opener require diagnostic equipment technicians carry.
- Repeated reversal despite clean sensors: Persistent problems often point to wiring or logic board faults.

Frequently Asked Questions
Why does my garage door reverse before touching the floor?
