Garage Door Won't Close: 8 Common Causes + How to Fix (Northern Virginia 2026)

If your garage door won't close, you're not alone. For homeowners in Bristow, Gainesville, Haymarket, and across Northern Virginia, a door that stops halfway, reverses on its own, or refuses to move is one of the most common service calls we handle. Nearly 30% of all garage door malfunctions are sensor-related, and most can be resolved within the hour.

Why a Garage Door Won't Close: Start Here

Before diving into the 8 causes, take 30 seconds to observe what's happening. The behavior of the door tells you a lot. A door that doesn't move at all points to a sensor, power, or remote issue. A door that reverses when closing points to sensors, travel limits, or an obstruction. A door that won't close all the way likely has a limit switch setting or track obstruction. A door that moves unevenly or makes a loud bang may have a broken spring or cable. A door that stops halfway likely has a track issue, roller problem, or spring failure.

Cause #1: Misaligned or Dirty Safety Sensors

This is the #1 reason a garage door won't close. All garage doors sold in the United States since 1993 are required by federal law to have photoelectric safety sensors. These sensors sit about 4 to 6 inches off the ground on both sides of the door opening. One side sends an invisible infrared beam to the other. If anything breaks that beam or if sensors are dirty or misaligned, the door stops or reverses.

How to fix it: Look at both sensor units. Each should show a steady indicator light. If a light is off or blinking, check for visible obstructions and clear anything within a foot of either sensor. Wipe both sensor lenses with a clean, dry microfiber cloth. If lights are still blinking, loosen the mounting wing nut on the bracket, gently rotate the sensor until the light turns steady, and retighten. Test the door.

Cost if you need professional help: $110-$230 all-in for a sensor cleaning, alignment, or replacement. Sensor parts alone run $20-$60 per pair.

Cause #2: Sunlight Interference

Direct sunlight can fool a sensor into thinking the beam is interrupted. This happens most often in the morning or late afternoon when the sun's angle aligns with the sensor's eye. A door that closes fine at noon but reverses every morning is a classic sign of sunlight interference. You can block the sunlight with a small cardboard shade taped around the sensor housing, or buy sun shield covers designed for your sensor model. Cost: $0-$15 if you DIY.

Cause #3: Dead or Weak Remote Batteries

Dead batteries are responsible for a surprising number of garage door calls every year. Cold weather makes this worse - battery performance drops significantly below 40 degrees F, and Northern Virginia winters regularly push overnight lows into the 20s and 30s from December through February. Signs: door doesn't respond to the remote at all, or responds when you use the wall button but not the remote. Replace batteries with fresh alkaline AA or AAA batteries. Cost: $3-$10 for replacement batteries.

Cause #4: Incorrect Travel Limit Settings

Every garage door opener has travel limit settings that tell the motor how far to move the door when opening and closing. If the close limit is set too short, the door stops before it reaches the floor. If it's set to see the floor as a barrier, the door may reverse before it fully closes. Locate the limit adjustment screws on the back or side of the motor unit. On most models, there are two screws labeled UP and DOWN. Turn the DOWN screw clockwise in small increments (about 1/4 turn) and test the door each time until it closes flush with the floor. Cost: $0 if you adjust it yourself; $50-$150 if a technician handles it.

Cause #5: Bent, Dirty, or Obstructed Tracks

The tracks guide your door's rollers as it moves up and down. If a track is bent, misaligned, or packed with debris, the rollers can't travel freely. Temperature swings between January lows and July highs cause metal to expand and contract, which can gradually pull track mounting brackets loose. For minor issues, clear debris inside the tracks, wipe the interior with a damp cloth, lubricate with a lithium-based spray, and tighten any loose mounting bolts. If the track is visibly bent or warped, call a licensed technician. Track repair typically costs $85-$300.

Cause #6: Broken Springs or Cables

If you heard a loud bang from your garage and then your garage door won't close, a broken torsion spring is almost certainly the cause. Springs counterbalance the weight of the door. When one breaks, the opener can't handle the full weight. Do not attempt to manually open, close, or operate the door. Do not try to fix the spring yourself. Torsion springs store hundreds of pounds of tension and can cause serious injury or death if handled without proper tools and training. This is the clearest call-a-professional situation in all of garage door repair. Spring replacement runs $300-$650 to replace both springs. Cable replacement runs $85-$200 per cable.

Cause #7: Worn or Damaged Rollers

Rollers are the small wheels that run inside the tracks, allowing the door to travel smoothly up and down. Most residential doors have 10 to 12 rollers. Over time - typically 5 to 7 years on standard nylon rollers - they wear down, crack, or break. A damaged roller can jam in the track, causing the door to stop mid-travel or refuse to close fully. Cost: $95-$200 for professional roller replacement on a full door. DIY parts run $5-$15 per roller.

Cause #8: Faulty Opener Motor, Circuit Board, or Wiring

If you've ruled out all of the above and the door still won't respond, the problem may be inside the opener unit itself. Common internal failures include a burned-out motor, a fried circuit board (usually caused by a power surge), or wiring issues. Try unplugging the opener for 60 seconds and plugging it back in. Look at the indicator light on the opener - most manufacturers publish a blink code guide. Circuit board replacement runs $150-$350 including labor. A full opener replacement costs $200-$500 installed.

When to Call a Professional

Call a licensed technician for: broken or damaged springs (never DIY - serious injury risk), broken or frayed cables, bent track sections, circuit board or opener motor failure, wiring repairs, and bottom roller replacement (connected to spring system). A licensed garage door technician in Northern Virginia typically charges $63-$110 per hour. Most jobs are completed in one to two hours.

Conclusion: Key Takeaways

If your garage door won't close, here's what to do in order: (1) Check the sensors first - clean both lenses, look for obstructions, and make sure both indicator lights are steady. This resolves the majority of cases. (2) Try the wall button, not just the remote. If the wall button works and the remote doesn't, the problem is the remote or its batteries. (3) Look at the door's behavior - reverses immediately means sensors or limits; stops halfway means track or roller; won't move at all means spring, cable, or power. (4) Lubricate twice a year. (5) Call a pro for springs, cables, and opener internals. A garage door that won't close is a security risk. Most causes are fixable the same day - often within the hour.
