Your garage door is something you expect to work without fail—until one day, it doesn’t. A stuck garage door can bring your entire day to a hard stop, especially if your car is trapped inside. Whether it won’t open, won’t close, or is frozen somewhere in between, you don’t have time to guess what’s wrong. This step-by-step troubleshooting guide will walk you through the most common garage door issues and help you decide when to call in the pros.
If you’re searching “garage door stuck” or “garage door opener not working,” start here.
Step 1: Stay Safe
Before touching anything, make sure the door isn’t at risk of slamming shut or suddenly falling. If it’s partially open, keep people, pets, and vehicles clear. Avoid trying to force the door manually. Garage doors are heavy, and the springs are under tension.
Step 2: Check the Power Source
It sounds obvious, but you’d be surprised how many times the issue is simply a power outage or unplugged opener. Make sure:
- The opener is securely plugged into a working outlet.
- The circuit breaker hasn’t tripped.
- Your opener unit shows signs of power (lights, display, etc.).
If the garage door opener has no signs of life, your problem may be electrical.
Step 3: Test the Remote and Wall Button
Try opening the door using both the remote and the wall-mounted control. If one works and the other doesn’t, the issue could be with the batteries or signal in the remote.
Troubleshoot the remote:
- Replace the batteries.
- Reprogram the remote.
- Check for interference from LED bulbs or wireless devices.
Step 4: Inspect the Safety Sensors
Modern garage doors are equipped with photo-eye sensors near the base of the tracks. These sensors prevent the door from closing on objects, pets, or people.
If your door won’t close:
- Check for dirt or cobwebs on the lenses.
- Make sure the sensors are aligned.
- Confirm that the lights on both sensors are solid (not blinking).
Misaligned or blocked sensors are one of the most common reasons a garage door won’t close.
Step 5: Try Manual Release
Every garage door opener has a manual release—usually a red cord hanging from the opener track. Pulling it disengages the door from the opener so you can try moving the door by hand.
Here’s what to look for:
- If the door opens and closes easily by hand, the opener is likely the problem.
- If the door is difficult or impossible to move, you may have a spring, roller, or track issue.
Use caution. If the door is stuck open and falls, it can cause injury or damage.
Step 6: Inspect the Tracks and Rollers
Debris, dents, or misalignment in the tracks can stop the door from moving smoothly.
Check for:
- Obstructions in the track (stones, leaves, tools).
- Bent or warped sections.
- Rollers that are stuck, worn, or popped out.
Use a flashlight and inspect both sides of the track all the way up.
Step 7: Listen for the Motor
When you hit the opener, listen. Do you hear the motor running but the door not moving? Or nothing at all?
Common sounds and what they mean:
- Motor runs but nothing happens: The door may be disengaged or a drive gear may be broken.
- Clicking or humming only: Could be a faulty capacitor or burnt-out motor.
- No sound at all: Electrical issue or fried opener board.
This step helps you isolate if the problem is with the opener unit or the physical door.
Step 8: Check the Springs
Torsion or extension springs are essential for lifting the weight of your door. If one breaks, the opener may not have enough force to lift the door.
To check:
- Look for a visible break in the spring.
- Listen for a loud “bang” that may have happened earlier (a common sign of spring failure).
- If the door is incredibly heavy or won’t budge manually, it could be a broken spring.
Important: Don’t attempt to repair or replace springs yourself. They are extremely dangerous when under tension.
Step 9: Look at the Cables and Hinges
Frayed, loose, or broken cables can cause uneven lifting or jamming. Hinges that have snapped can cause a panel to lock up or twist in the track.
Signs to look for:
- One side of the door lifting higher than the other.
- Cables hanging loose or appearing shredded.
- Hinges that look bent or cracked.
These problems often occur with older doors or after minor accidents.
Step 10: Reset the Opener System
If your opener has a logic board or display, try resetting it.
To do this:
- Unplug the opener.
- Wait 30 seconds.
- Plug it back in and test.
Sometimes, openers just need a reboot to clear internal errors.
If the system continues to fail after a reset, the issue could be deeper within the opener’s logic board or sensors.
When to Call in the Pros
If you’ve walked through all ten steps and your garage door still won’t budge, it’s time to bring in a professional. Garage door systems involve complex mechanical parts and high-tension springs that can cause injury if mishandled.
Contact a professional if:
- The springs are broken.
- The opener motor is unresponsive.
- You suspect a structural issue with the tracks or frame.
- You’ve tried manual operation and the door is still stuck.
Final Thoughts
Troubleshooting a stuck garage door doesn’t have to be overwhelming. With a methodical approach, you can isolate many common problems and even fix some on your own. However, knowing your limits is just as important as knowing the steps.
Whether your garage door won’t open, won’t close, or the opener seems dead, following these ten steps can help you get closer to a solution. And if you need local help, search for trusted garage door repair services near you to ensure your system gets back up and running safely and quickly.
Still stuck? Don’t stress. A reliable garage door technician can have you back on track in no time—and might even show you how to prevent it from happening again.
