Garage Door Won't Open? 7 Causes and How to Fix Them

Garage door won't open? Here are the 7 most common causes — from dead remotes to broken springs — plus how to fix each and what it costs.

A garage door that will not open is more than an inconvenience — it can trap your car and leave your home unsecured. The good news is that some causes are simple fixes you can handle in minutes, while others need a professional. Here are the seven most common reasons a garage door will not open, and what to do about each.

Why Won't My Garage Door Open?

The most common reasons a garage door will not open are a dead remote battery, an engaged lock or vacation mode, misaligned safety sensors, a broken spring, a snapped cable, a door off its track, or a failed opener motor. Start with the simple electrical checks before assuming the worst.

1. Dead Remote or Keypad Battery

If the wall button works but the remote or keypad does not, the battery is the likely culprit. Replace the remote battery and re-test. If the keypad still fails, reprogram it following the opener manual. This is the cheapest fix and the first thing to check.

2. Opener Unplugged or in Lock / Vacation Mode

Confirm the opener is plugged in and the outlet has power. Many wall consoles have a "lock" or "vacation" button that disables remotes to prevent unauthorized entry — if it was pressed by accident, the door will not respond to remotes. Hold the lock button to toggle it off.

3. Misaligned or Dirty Photo-Eye Sensors

The safety sensors near the floor on both sides of the door must face each other with a clear beam. If a sensor is bumped, dirty, or blocked, the door may refuse to close or behave erratically. Wipe the lenses with a soft dry cloth and gently realign them until the indicator lights are steady. Maryland's humid mornings can fog these lenses, so keep them clean.

4. Broken Torsion Spring

If you heard a loud bang like a gunshot and now the door will not lift — or the opener strains and reverses — a spring has likely snapped. This is not a DIY repair; springs hold hundreds of pounds of tension. Stop using the opener and book professional spring replacement. Spring failure is especially common in winter, as we explain in why springs break in Maryland winters.

5. Snapped or Frayed Lift Cable

The steel cables work with the springs to raise the door. A snapped cable can cause the door to hang crooked or jam. Because the system is under tension, cable replacement should be done by a technician. Expect roughly $130 to $200 for professional cable repair.

6. Door Off Its Track

If the door is visibly crooked, wedged, or the rollers have jumped the rails, it is off track and unsafe to operate. Do not force it. Learn the causes and repair process in our guide to a garage door off track, or call for off-track repair.

7. Worn-Out Opener Motor or Stripped Gears

If the motor hums but nothing moves, or the opener is silent with power confirmed, the drive gears or motor may have failed. Openers typically last 12 to 15 years. A garage door opener repair or replacement runs about $300 to $700 installed, depending on the model. Not sure which brand to choose? See our LiftMaster vs. Genie vs. Chamberlain comparison.

When Should You Call a Professional?

Handle the battery, power, lock-mode, and sensor checks yourself. But if the door will not lift, sounds like a spring snapped, has a broken cable, or is off track, stop and call a technician. Forcing a door in those conditions can cause injury or turn a small repair into a major one. Eagle Garage Door Services offers same-day and 24/7 service across Maryland.

Frequently Asked Questions

Why does my garage door open a few inches then stop?

A door that opens slightly then stops and reverses usually has a broken spring, a tension or force setting problem, or an obstruction the opener detects. Because a broken spring is the most common cause, avoid repeatedly running the opener, which can damage the motor, and have the springs inspected.

Can I open my garage door manually if it won't open?

If the springs are intact, pull the red emergency release cord while the door is fully closed, then lift by hand. Never pull the release on a partially open door with a suspected broken spring — it could crash down. During power outages, the emergency release is your primary way in unless your opener has a battery backup.

How much does it cost to fix a garage door that won't open?

It depends on the cause. A remote battery is a few dollars; sensor realignment is often free during a service call; spring replacement runs $300 to $550 for a pair; cable repair is about $130 to $200; and opener replacement is $300 to $700 installed.
