Why Won't My Garage Door Close? 9 Causes & Fixes

The 9 Most Common Reasons a Garage Door Won't Close

Work through these in order — the first four solve most cases without tools:

1. Misaligned photo-eye sensors

The two small sensors near the floor must face each other perfectly. A bumped trash can or broom shifts them, and the door reverses or refuses to move. Look for a blinking LED instead of solid — realign by hand until both lights hold steady.

2. Something blocking the beam

Leaves, cobwebs, snow or even strong sunlight across one sensor can trip the safety reversal. Wipe both lenses with a soft cloth and clear the doorway.

3. Force or travel limits set wrong

If the opener starts closing then reverses, the force setting may be too sensitive or the travel limits confused — common after a power outage. Reset per your opener manual, or let a technician calibrate it.

4. Remote or wall panel fault

Dead batteries, a locked wall panel (an icon of a padlock), or a remote that lost its programming. Test the wall button: if the door closes from the wall, the opener is fine — the remote is the problem.

5. Snapped spring

A loud bang followed by a door that won't move — or moves an inch and strains — means a broken torsion or extension spring. This is a same-day pro job; the door is too heavy to force.

6. Cable off the drum

A dangling or loose cable leaves the door crooked and jammed. Don't keep pressing the button — it can jump the tracks and multiply the damage.

7. Worn opener gears or board

The motor hums but nothing moves: stripped gears or a failed logic board. We repair all major brands or quote a like-for-like replacement the same visit.

8. Door off its tracks

If the door is visibly crooked or hanging, stop pressing the button. Rollers out of the track need a professional reset before the door falls.

9. No power to the opener

Tripped breaker, unplugged unit or a dead breaker after a storm. If the outlet is dead, check the GFCI — and remember a battery-backup opener still works in an outage.

Quick Checks Before You Call (5 Minutes)

If any of these checks points to springs, cables or an off-track door — stop there. Those parts are under dangerous tension and are a licensed-technician job.

• ✓Wall-button test: if it closes from the wall but not the remote, it's a remote or keypad issue — cheap fix.
• ✓Lens wipe test: clean both sensor eyes with a dry cloth and realign until the LEDs go solid.
• ✓Obstruction sweep: clear the entire opening, including the sensor rails.
• ✓Manual release: with the door CLOSED, pull the red cord to test if the door moves smoothly by hand — resistance means springs or tracks.
• ✓Power check: confirm the opener is plugged in and the breaker is on.
