Garage Door Won’t Close — Full Troubleshooting Guide
Garage Door Won’t Close — Full Troubleshooting Guide
A garage door that won’t close is one of the most common calls we get, and it’s usually one of a handful of causes. Work through this list before assuming you need a full repair.
1. Check the Photo-Eye Sensors First
This is the most common cause by far. Look for anything blocking the beam between the two sensors near the floor, check that both indicator lights are solid (not blinking), and clean the lenses if they’re dusty. See our full sensor troubleshooting guide for details.
2. Look for a Track Obstruction
Check both tracks for debris, ice buildup in winter, or anything that could be blocking the rollers from moving freely.
3. Check the Close-Force and Limit Settings
Most openers have adjustable limit and force settings that tell the door how far to travel and how much resistance to detect before reversing. If these are set incorrectly — sometimes after a power outage or opener reset — the door may stop short of closing. Check your opener’s manual for how to access these settings.
4. Listen for What’s Actually Happening
- Door starts to close, then reverses — sensor issue (most common) or force setting too sensitive
- Door doesn’t move at all when you press the button — check the opener’s power, breaker, and remote batteries
- Door moves partway then stops — possible obstruction, worn roller, or track misalignment
- Opener strains or grinds but door doesn’t close — could be a spring issue adding resistance, or a stripped gear
5. Try the Manual Release
If nothing above resolves it, disconnect the opener using the manual release cord and try closing the door by hand (carefully — it will be heavy). If it closes smoothly manually but not with the opener, the issue is with the opener itself, not the door or springs.
If the door is heavy or resists closing manually, stop — that could indicate a spring problem, which isn’t safe to force. Call for service instead.
Frequently Asked Questions
Why does my garage door stop halfway when closing?
Usually a track obstruction, a worn roller, or an incorrectly set travel limit on the opener. Check the track first, then the opener’s limit settings.
Is it safe to close my garage door manually if the opener isn’t working?
Generally yes, using the manual release cord, as long as the door isn’t unusually heavy or resistant — which could signal a spring problem.
When should I call a professional instead of troubleshooting myself?
If you’ve checked sensors, tracks, and basic settings without success, or if the door feels unusually heavy, it’s time to call — especially if a spring or cable issue is possible.
