Garage Door Won't Close? 8 Fixes Before You Call a Pro
Updated June 2026 · 5 min read
Safety first: Never put your hands near the springs, cables, or the bottom edge of a moving door. If you hear a loud bang or see a snapped cable, stop and call a pro.
You hit the button, the door starts down, then reverses. Or it doesn't move at all. Before you call us (and we're happy to come out), try these eight checks in order — most 'won't close' problems are 10-minute fixes.
1. Check the safety sensors
The two little eyes near the floor on each side of the door. If one LED is off or blinking, they're misaligned or dirty. Wipe both lenses with a soft cloth and gently adjust until both LEDs are solid. This fixes ~60% of 'won't close' calls.
2. Look for obstructions in the sensor beam
A garbage can, broom, leaf, or even direct sunlight can break the beam. Move anything in the door's path.
3. Pull the disengage cord and try manually
If the door is heavy or doesn't stay halfway open on its own, your spring is broken or out of balance — that's a pro fix. If it moves smoothly, the problem is the opener.
4. Check the wall button vs the remote
If the wall button works but the remote doesn't, replace the remote battery. If neither works, the opener logic board may be fried.
5. Look at the close-force / travel limits
Most openers have small adjustment screws or buttons on the back. If the door slams or stops short, the travel limits drifted. Manuals are online by model.
6. Check the lock button on the wall console
Wall consoles have a 'Lock' or 'Vacation' button. If it's been bumped on, remotes are disabled. Press to unlock.
7. Inspect the rollers and tracks
Look for a roller out of the track or a bent track section. If you see one, do NOT force the door — call a pro before the cable derails.
8. Listen to the opener motor
If it hums but doesn't move, the drive gear is stripped. If it does nothing, the logic board or capacitor is dead. Both are repairable but require service.
Still won't close?
If you've worked through all eight and it still won't close, the issue is mechanical — spring, cable, logic board, or motor. We diagnose for free with any repair.
Pro tip: 60% of 'won't close' calls in Denver are dirty or misaligned safety sensors. Always check those first.
