A garage door that refuses to open is more than a minor inconvenience. It can trap your car inside, disrupt your morning routine, and create safety concerns for your home. For many homeowners, this issue appears out of nowhere. One day the door works fine, and the next day it won’t budge.
At BWI Garage Doors, we hear this problem every day from customers across Maryland. The good news is that most garage door issues follow a predictable pattern. If your door isn’t opening, the cause is usually one of a handful of mechanical or electrical problems. Some are simple to fix. Others require a trained technician.
Below, we break down the 7 most common causes, how to troubleshoot each one, and when to call for professional repair.
1. Broken or Worn Garage Door Springs
Garage door springs do the heavy lifting. They counterbalance the weight of the door, allowing it to rise smoothly. When a spring breaks, the opener can’t lift the door.
How to Tell If a Spring Is Broken
A broken torsion or extension spring is usually easy to spot:
- You may hear a loud snap or bang.
- The door may be very heavy when you try to lift it manually.
- The top of the door may tilt or look uneven.
- The opener strains but can’t lift the door.
Why It Happens
Springs wear out over time. Most are rated for 10,000 cycles (one open and close). Frequent use, lack of lubrication, and seasonal temperature changes can shorten their life.
Can You Fix It Yourself?
No. Spring replacement is one of the most dangerous garage door repairs. There is heavy tension on the springs, and an incorrect adjustment can cause serious injury.
Safe Fix
Call a trained professional. BWI Garage Doors replaces torsion and extension springs with properly sized, long-lasting parts. We also balance the door and test all safety mechanisms to make sure it operates smoothly.
2. Dead Batteries in Your Remote or Wall Keypad
This is one of the most overlooked reasons a garage door won’t open. Batteries eventually die, even if the remote looks new.
Signs the Batteries Are the Problem
- The remote works only when you’re very close to the door.
- The wall keypad lights are dim or flicker.
- The remote shows no response at all.
Quick Fix
Replace the battery in the remote or keypad. Most take standard coin-cell batteries or AA/AAA batteries. After replacing the battery, test the door again.
If It Still Won’t Work
The remote may need reprogramming, or there may be interference from nearby electronics. In that case, a technician can reset the opener’s settings.
3. Misaligned or Blocked Safety Sensors
Modern garage doors have photo-eye sensors near the bottom of the tracks. These sensors prevent the door from closing on objects, pets, or people. When they’re misaligned, dirty, or disconnected, the door may not open or close.
How to Diagnose Sensor Issues
Check for these signs:
- Blinking sensor lights
- A closed door that won’t rise when you press the button
- The door moves a few inches, then reverses
Common Causes
- Dust or cobwebs on the lens
- Bumped sensors from yard tools or kids
- Loose wiring
Easy Fix
- Clean the sensor lenses with a soft cloth.
- Make sure both sensors are aligned. The lights should be solid, not flashing.
- Inspect for loose wires.
When to Call a Professional
If cleaning and alignment don’t help, the wiring or the sensor itself may be damaged. A technician can replace the sensor or repair the connection quickly.
4. Problems With the Garage Door Opener
Sometimes the opener motor is the source of the breakdown. Over time, gears inside the opener can strip, circuit boards can fail, or the motor can burn out.
Warning Signs of Opener Failure
- The opener hums but the door doesn’t move.
- The lights on the opener flash repeatedly.
- The opener runs for a few seconds and then shuts off.
- You smell something burnt.
Simple Fixes to Try First
- Make sure the opener is plugged in.
- Check the circuit breaker.
- Reset the opener by unplugging it for 30 seconds.
When the Opener Needs Repair or Replacement
If the opener continues to struggle, a technician may need to:
- Replace worn gears
- Install a new circuit board
- Reprogram the opener
- Replace the entire motor
At BWI Garage Doors, we service all major brands, including LiftMaster, Chamberlain, Genie, and Craftsman.
A garage door can come off its track for many reasons: impact, wear, a bent track, or roller problems. When this happens, the door can’t lift properly.
5. Garage Door Is Off Track
How to Tell If Your Door Is Off Track
- The door looks crooked or stuck at an angle.
- You hear scraping or grinding noises.
- The rollers are visible outside the metal track.
Why It Happens
- Loose bolts on the track
- Bent or damaged tracks
- Old or broken rollers
- Obstructions in the path
What You Can Do Safely
You can check for obvious debris or loose bolts. Besides that, don’t operate the door. Trying to force it open can make the damage worse.
Professional Fix
A technician can realign the tracks, replace rollers, tighten the hardware, and test the door balance. This repair normally restores smooth movement.
6. The Door Is Manually Locked
Many homes have manual locks on the garage door. If they’re accidentally engaged, the opener won’t lift the door even though everything else is working fine.
How It Happens
- A family member locks it without realizing.
- The lock engages when the door is closed quickly.
- Old or rusted locks stick in place.
Quick Fix
Check the center handle or side lock bars. If the lock is engaged, simply unlock it. If it’s stuck, a little lubricant may help release it.
If It Won’t Unlock
A technician can free or replace the lock. This is usually a quick repair.
7. Damaged or Worn Garage Door Cables
Cables work with the springs to lift the door. Over time, they can fray, rust, loosen, or snap. If a cable breaks, the door may lift unevenly or not lift at all.
Signs of Cable Problems
- Loose cables hanging near the sides
- A door that rises on one side but not the other
- Jerky or uneven movement
- Visible fraying
Why Cables Break
- Rust or corrosion
- Old age
- Excess tension
- Exposure to moisture
Can You Repair Cables Yourself?
No. Like the springs, cables hold a large amount of tension. Attempting to replace them without the right tools is risky.
Safe Fix
A professional can replace the cables and rebalance the system. This repair is important for safety and smooth operation.
How to Troubleshoot Safely Before Calling a Technician
Here’s a quick checklist you can try before scheduling a repair:
- Check the remote batteries.
- Make sure the opener is plugged in.
- Inspect the safety sensors for dirt or misalignment.
- Look for visible damage on the springs or cables (don’t touch them).
- Make sure the manual lock isn’t engaged.
- Remove any items blocking the tracks.
If the door still won’t open, avoid forcing it. Forcing a stuck door can cause additional damage.

How to Prevent Your Garage Door From Getting Stuck Again
Preventive maintenance goes a long way. Here are a few simple steps:
Lubricate Moving Parts
Apply silicone-based lubricant to:
- Hinges
- Rollers
- Springs
- Tracks
Never use heavy grease. It attracts dirt and creates buildup.
Inspect the Door Monthly
Look for rust, loose bolts, worn rollers, or damaged weather stripping.
Test the Balance
Disconnect the opener and lift the door halfway. It should stay in place. If it drops, the springs may need adjustment.
Check the Sensors
Keep them clean and aligned.
Schedule Annual Professional Maintenance
Yearly tune-ups help avoid surprise breakdowns.
