If your garage door won’t open, the most common causes are a broken spring, a power or opener problem, the door being in “lock” mode, or a dead remote. Several of these you can check yourself in a minute or two. Here’s how to narrow down the problem — and when to call for same-day help in Houston.
The most common reasons a garage door won’t open
- Broken torsion spring. If you heard a loud bang and the door is now too heavy to lift, a spring almost certainly broke. Don’t force it — call a professional.
- No power or opener fault. Check the outlet, the breaker, and whether the opener motor hums or responds at all. A failing opener may need repair.
- Lock mode engaged. Many openers have a vacation/lock setting that disables the remotes. Look for a lock icon on the wall button.
- Dead remote or keypad. Try fresh batteries and the hardwired wall button. If the wall button works but the remote doesn’t, the remote is the problem.
- Blocked or faulty sensors. Sensors mostly affect closing, but a fault can confuse the opener — clear and check them.
- Door off track. If the door is crooked or jammed in the tracks, stop and call for repair before using it again.
Quick checks you can do safely
Test the wall button versus the remote to isolate a remote issue, confirm the opener has power, look for a lock icon, and glance at the springs above the door for a visible gap. What you should not do is force a heavy door open or attempt any spring or cable work yourself — those are high-tension parts.
Can I open the door manually?
Yes — pull the red emergency release cord to disconnect the opener, then lift the door by hand. But only do this if no spring is broken; with a broken spring the door can slam down. When in doubt, leave it closed and call a technician.
When it’s the spring (the most common culprit)
A broken torsion spring is the number-one reason a door won’t open. Springs are wound under extreme tension and are not a DIY fix — a technician replaces them safely, usually within an hour. See our garage door spring repair cost guide for what to expect.

Frequently asked questions
The opener hums but the door won’t move — why? Usually a broken spring or a stripped opener gear. Stop trying and call a pro.
My remote stopped working — what now? Replace the batteries and try the wall button; the remote may simply need reprogramming.
Is it safe to keep pressing the opener? No — repeated attempts against a broken spring or jammed door can burn out the opener.
