Garage Door Won't Open? 9 Causes and How to Fix Each (Northern Virginia 2026)

A garage door won't open for one of nine reasons — and most of them take less than five minutes to diagnose yourself. In Northern Virginia, a few of those causes are more common than elsewhere: frozen seals in January, spring failures accelerated by our freeze-thaw winters, and remote interference from the dense electronics in newer Bristow and Gainesville homes. This guide walks you through every cause in order from easiest to hardest to fix.

Before You Start: The 60-Second Safety Check

If you heard a loud bang before the door stopped working, do not force it. A door that won't move after a loud snap almost certainly has a broken spring. Stop pressing the button and skip directly to Cause 2 below.

Cause 1: Dead Remote Battery or Signal Problem

Before assuming anything is mechanically wrong, try opening the door from the hardwired wall button inside the garage. If the wall button works and the remote doesn't, the problem is the remote — not the door.

Fix cost: $5–$15 to replace a battery or remote. Reprogramming is free.

Cause 2: Broken Torsion or Extension Spring

This is the cause when you hear a loud bang from the garage, and afterward the door either won't move at all or feels extraordinarily heavy when you attempt to lift it manually. Do not use the door. This is always a professional repair — torsion springs store 150–200 lbs of rotational force.

Fix cost: Spring replacement in Northern Virginia runs $150–$350 for a single spring or $350–$650 for a pair.

Cause 3: Emergency Release Cord Was Pulled

If someone pulled the red emergency release cord, the opener motor will run but the door won't move. Pull the cord down and back toward the motor unit to re-engage the trolley latch.

Cause 4: Manual Lock Is Engaged

Most garage doors have a manual slide lock that physically bolts the door to the track. When engaged, the opener will strain but the door cannot move. Look along the middle horizontal bar for a slide handle and disengage it.

Cause 5: Broken or Snapped Cable

When a cable breaks, the door loses its guided support on one side and typically gets stuck or jams against the track. Stop using the door. Cable replacement involves releasing spring tension and is a professional-only repair.

Cause 6: Door Frozen to the Ground

Northern Virginia winters combine freezing temperatures that can freeze the rubber bottom seal solid to the concrete floor. Do not press the opener button repeatedly. Use a plastic ice scraper, warm water, or a hair dryer to break the ice seal, then pull the emergency release and open manually.

Cause 7: Misaligned or Damaged Track

If the tracks are bent, warped, or shifted out of alignment, the rollers bind and the door stops moving. Track alignment runs $125–$200. Track section replacement runs $150–$300 per section including labor.

Cause 8: Power Outage or Tripped Circuit Breaker

Check whether the opener is plugged in, whether the outlet is working, and whether a circuit breaker has tripped. After a power outage, some openers reset their limit settings and may need reprogramming.

Cause 9: Worn Opener Gears, Faulty Logic Board, or Dead Motor

If you've checked everything above and the door still won't open, the problem is inside the opener itself. Gear replacement costs $75–$150. Logic board replacement costs $100–$200 in parts plus labor. A new opener installed runs $300–$700.

Key Takeaways

• Start simple: dead batteries, disengaged trolleys, and manual locks cause more calls than broken hardware.

• A loud bang means a broken spring. Stop using the door immediately.

• Frozen seals are a Northern Virginia seasonal reality. Apply silicone lubricant to your bottom seal every November.

• Openers 12+ years old showing failures are often better replaced than repaired.
