What Do You Do If Your Garage Door Won’t Open? Common Causes and Quick Fixes
When your garage door refuses to budge, several things might be at play. The good news is that many problems have simple solutions you can try yourself before calling a technician.
1. Check the Remote Control and Wall Switch
The first and easiest step is to verify that your remote control or wall switch is working correctly.
- Replace the remote battery. Dead batteries are a common culprit.
- Try the wall switch. If the door opens using the wall switch but not the remote, your remote might be faulty or need reprogramming.
- Ensure the remote is within range and that there are no obstacles blocking the signal.
2. Inspect the Garage Door Sensors
Most modern garage doors have safety sensors near the floor on either side of the door. These sensors prevent the door from closing if something blocks the path.
- Check if the sensors are aligned properly. Misaligned sensors can prevent the door from opening.
- Clean the sensor lenses to remove dust or spider webs.
- Look for blinking lights on the sensors. A blinking red or orange light usually indicates a problem.
3. Examine the Garage Door Springs and Cables
The springs and cables help lift the heavy garage door. If a spring breaks or a cable snaps, the door won’t open.
- Listen for a loud bang. A broken spring often makes a noticeable noise.
- Look for visible damage. If you see a gap in the spring or frayed cables, do not attempt to open the door manually.
- Call a professional. Repairing springs and cables is dangerous and should be handled by experts.
4. Inspect the Garage Door Tracks and Rollers
Debris, dents, or bent tracks can cause the garage door to jam.
- Look for any obstacles such as leaves, dirt, or small objects in the tracks.
- Check for visible damage to the tracks or rollers.
- Lubricate the rollers and tracks with a silicone-based lubricant to improve movement.
5. Test the Garage Door Opener Motor
Sometimes the issue lies within the garage door opener motor itself.
- Listen for any noise when pressing the button. If the motor hums but the door doesn’t move, it could be a broken gear inside the opener.
- Reset the opener by unplugging it for a few minutes and plugging it back in.
- Look for indicator lights on the opener that may signal a problem.

- Inspect tracks for bends or blockages.
- Lubricate rollers, hinges, and tracks.
Step 6: Reset the Garage Door Opener
- Unplug the unit for 30 seconds.
- Plug it back in and test the door.
- Consult the manual to perform a factory reset if problems persist.
