10 Reasons Your Garage Door Won’t Open (And What to Do About It)

By Master Pro Garage Door  |  Serving Baltimore, Owings Mills, Pikesville & Surrounding Areas

When your garage door won’t open Maryland mornings are the worst time to deal with it — here are the most common causes and what to do about each one.

It happens at the worst possible moment — you’re running late for work, you press the button, and nothing happens. Your garage door won’t open. Before you panic, know that this is one of the most common service calls we handle at Master Pro Garage Door across the Baltimore metro area. In most cases, the cause is straightforward once you know what to look for.

This guide walks you through the 10 most common reasons a garage door won’t open, what you can safely check yourself, and when it’s time to call a professional.

1. Broken Torsion Springs

This is the number one reason garage doors suddenly stop working — and it’s one of the most dangerous to attempt fixing on your own.

Torsion springs are the large, coiled springs mounted above your garage door. They bear the full weight of the door and do most of the heavy lifting every time you open or close it. When a torsion spring breaks, you’ll typically hear a very loud bang — similar to a gunshot — followed by the door becoming too heavy for the opener to lift.

What to look for: A visible gap or separation in the coiled spring above the door.

What to do: Do not attempt to operate the door manually or with the opener. A broken torsion spring under tension can cause serious injury. Call a professional garage door technician immediately.

At Master Pro Garage Door, torsion spring replacement is one of our most common repairs throughout Owings Mills, Reisterstown, and Pikesville. We carry springs for all door sizes and can typically complete the repair the same day.

2. Snapped or Disconnected Cables

Garage door cables work alongside the springs to lift and lower the door evenly. When a torsion spring breaks, the cable on that side often snaps under the sudden shift in tension. Even without a spring failure, cables can fray and snap over time due to wear.

What to look for: A cable lying loose on the garage floor, or the door hanging unevenly (one side lower than the other).

What to do: Do not try to operate the door. Like spring repairs, cable replacement involves components under high tension and should only be handled by a trained technician. Contact Master Pro Garage Door for same-day cable repair service in the Baltimore area.

3. Dead or Disconnected Power Source

It sounds too simple to be the answer, but it happens more often than you’d think — especially after a storm or power outage in the Baltimore area.

Check these first:

• Is the opener plugged into the outlet? (The cord can work itself loose over time)
• Has the outlet’s circuit breaker tripped? Go to your electrical panel and check
• Is there a GFCI outlet nearby that has tripped? Press the reset button

If the outlet has power but the opener still won’t respond, the issue is likely with the opener unit itself. Our team services all major brands including LiftMaster and Chamberlain — call (443) 619-7759 for same-day opener service.

4. Blocked or Misaligned Photo Eye Sensors

All garage doors manufactured after 1993 are required by law to have photo eye sensors — two small devices mounted near the bottom of the door tracks, about 4–6 inches off the ground. They send an invisible beam across the door opening. If anything breaks that beam, the door won’t close (and sometimes won’t open either).

What to look for:

• A blinking or solid red light on one of the sensors (instead of both showing steady green/amber)
• Dirt or spider webs covering the sensor lens
• One sensor that appears physically knocked out of alignment

What to do: Wipe the sensor lenses clean with a soft cloth. Check that both sensors are pointing directly at each other. If the lights are still blinking, gently adjust the sensor bracket until both lights go steady. This is one of the few issues Maryland homeowners can safely fix themselves without tools.

5. Remote Control Problems

If the door opens fine from the wall button but not from your remote, the issue is almost always one of three things:

• Dead battery — replace it first before anything else
• Remote out of range — most remotes work up to 30 feet; if you’re further away or there’s interference from nearby devices, move closer
• Remote needs reprogramming — this can happen after a power outage or if someone accidentally cleared the opener’s memory

Check your opener’s manual for reprogramming instructions, or call us at (443) 619-7759 and we can walk you through it over the phone.

6. Disconnect Switch Has Been Activated

Every garage door opener has a manual disconnect — usually a red rope or cord hanging from the trolley rail. It’s designed to let you operate the door by hand during a power outage.

If this cord has been pulled (by a child, accidentally, or during a power outage), the door is in manual mode and the opener won’t move it.

What to do: Pull the cord back toward the door (in the opposite direction from how you pulled it to disconnect), then try the opener again. You should feel or hear it re-engage with the trolley.

7. Sensitivity Settings Out of Adjustment

Garage door openers have adjustable sensitivity settings that determine how much force the motor uses to open and close the door. If these are set incorrectly — especially on a newly installed opener — the door may refuse to open or close fully.

Signs this is the issue:

• The door starts to open, reverses immediately, and stops
• The door moves partially then stops for no apparent reason
• The door closes but then reopens on its own

Consult your opener’s manual for the sensitivity adjustment screws (usually labeled “open force” and “close force” on the back of the unit). If you’re unsure, this is a quick fix for a technician — call us at (443) 619-7759.

8. Limit Settings Need Adjustment

Limit settings tell the opener how far to travel before stopping. If these are miscalibrated, the door might think it’s fully open when it’s only halfway up, or it might close and immediately reopen because the opener thinks it hit an obstruction. This is more common after a new opener installation or if the opener is older and the settings have drifted. Our garage door opener service includes checking and recalibrating limit settings as part of every tune-up.

9. Door Has Come Off Its Track

If your garage door has come off its track, it won’t slide smoothly and may jam completely. This can happen from a car bumping the door, a broken spring causing uneven tension, or simply worn rollers over time. Our team handles roller replacement and track realignment throughout the Baltimore metro area.

What to look for: Visible bending or separation between the door rollers and the metal track, or a door that moves unevenly or scrapes against the frame.

What to do: Do not force the door open or closed — you can cause additional damage or injury. This is a repair that requires professional equipment to fix safely.

10. An Obstacle Is Blocking the Door

Garage doors are designed with safety in mind — they automatically reverse if they detect resistance while closing. If your door closes halfway and reverses, or won’t fully close, check the tracks for:

• Small rocks, dirt, or debris in the track channel
• A tool or object sitting in the door’s path
• Ice buildup along the bottom seal in winter (common during Maryland winters)

Wipe down the tracks with a clean cloth and remove any debris. If the door still reverses without any obvious obstruction, the issue is likely with the sensitivity settings or the photo eye sensors.

When to Call a Professional

You can safely handle a few of these issues yourself — dead batteries, dirty sensors, a tripped disconnect cord. But for anything involving springs, cables, tracks, or the opener motor, always call a licensed technician. These components are under extreme tension and can cause serious injury if handled incorrectly.

Frequently Asked Questions

How much does it cost to fix a garage door that won’t open in Maryland?

Costs vary depending on the cause. A simple sensor realignment may be free if you do it yourself. Spring replacement typically ranges from $150–$350 depending on spring type and door size. Cable replacement usually runs $100–$200. Call us at (443) 619-7759 for an exact quote.

Can I open my garage door manually if the spring is broken?

Technically yes, but it’s not recommended. A door with a broken spring can weigh 200–400 pounds and can fall rapidly without the spring’s support. We recommend leaving it closed and calling a technician.

How long do garage door springs last in Maryland?

Most torsion springs are rated for 10,000–20,000 cycles. With average use (4 opens/closes per day), that’s roughly 7–14 years. Maryland’s humidity and temperature swings can accelerate wear. Ask us about our preventative maintenance plan to extend the life of your springs and cables.

My garage door worked fine last night — why won’t it open this morning?

The most common overnight causes are a broken torsion spring (they often snap during the night when temperature drops), a dead remote battery, or a tripped circuit breaker. Start with the battery, then check your breaker panel, then visually inspect the spring above the door. If it’s a broken spring, call (443) 619-7759 for same-day repair.
