You’ve pulled the red emergency cord. You’ve tried to lift the door. And nothing moves — or worse, it’s jammed halfway and refusing to budge. When your garage door won’t open manually, it’s more than just a hassle; it’s a serious disruption.
Whether you’re managing deliveries at a commercial property or trying to get your car out of the garage at home, a stuck or jammed garage door can mean lost time, blocked access, and unexpected safety risks.
In this guide, we’ll walk you through:
- Why your garage door won’t open manually — even after pulling the cord
- What’s happening inside your garage door system
- How Florida’s humidity and storms make this problem worse
- What you can safely check yourself (and what you can’t)
- When it’s time to call a trained garage door technician
First, How Do You Manually Open a Garage Door?
If your garage door isn’t opening manually, the first question you’re probably asking yourself is, “am I doing this right?” Great place to start — because if the manual release isn’t engaged correctly, nothing else you try will work. Here’s exactly how to open most sectional garage doors and roller doors manually, whether at home or at a business.
Step 1: Make sure the garage door is fully closed.
This is important. Pulling the release cord when the door is open or partially open can cause the door to slam shut due to gravity. Always ensure it’s completely down before proceeding.
Step 2: Locate the red garage door emergency release cord.
This cord hangs from the trolley connected to your garage door opener. Its entire purpose is to disconnect the opener from the door so the door can move freely by hand.
Step 3: Pull the cord down and toward the door.
Many people tug it straight down, but the correct method is usually to pull down and then pull slightly toward the garage door. This motion forces the trolley to disengage fully. You should hear or feel a small click when the garage door mechanism releases.
Step 4: Lift the door with two hands.
Once disengaged, lift the door straight up using even pressure. Ideally, it should glide smoothly if the garage door springs and cables are intact.
If your garage door is too heavy to lift or won’t move at all, stop right there. That’s a sign of a deeper mechanical issue.
Step 5: To re-engage the garage door opener, pull the door down and hit the opener button.
The trolley should reconnect automatically. If it doesn’t, you may need to gently guide it back into position or pull the garage door emergency release cord forward again.
Why Manual Operation Matters
Overhead garage doors use a counterbalanced, spring-loaded mechanism designed to reduce the effort required to lift a door that can weigh anywhere from 150–400+ pounds.
Most overhead garage doors are designed to operate with an electric garage door opener and a manual release. Garage doors are spring-loaded or counterbalanced to reduce the effort required to lift the weight of the door.
When the garage door opener fails due to a power outage, mechanical breakdown, or storm-related surge, the red garage door emergency release cord is your backup plan. But what happens when that fails?
Why Your Garage Door Won’t Open Manually — Even With the Cord Pulled
If your garage door won’t budge after you’ve pulled the release cord, something in the lift system is no longer doing its job. You could be dealing with a simple mechanical failure, such as a broken garage door opener, or it could be a more serious internal issue.
A Broken Torsion Spring or Extension Spring
Your door may weigh over 300 pounds — or much more for commercial roll-up doors. Torsion springs (mounted above the door) or extension springs (along the track) are built to counterbalance that weight.
If one of these springs breaks or loses tension, your garage door becomes too heavy to lift, even by hand.
Signs include:
- A loud bang at the time of failure
- A visible gap in the spring
- A door that starts to lift and then slams down
- Complete resistance to manual movement
Garage door springs in highly humid environments, like coastal Florida, tend to have a significantly shorter cycle life due to corrosion.
A Snapped Cable or Unbalanced Garage Door
If one of the lift cables snaps or slips off its drum, the door will usually sag to one side. You’ll notice the door tilting or dragging — or it may jam completely.
Commercial overhead doors are especially vulnerable in Florida due to heavier weights and daily usage. When cables fail, your garage door won’t open manually because the system can no longer evenly support the load.
Damaged Rollers or Jammed Tracks
Whether your door is a sectional garage door or a roller door, it glides along a metal track using rollers.
Salt air, impact damage, or debris can bend those tracks or rust out the rollers, especially in coastal environments like South Florida. A jammed roller or warped track can lock your door in place, no matter how hard you pull the cord.
A Stuck Opener Trolley or Disengagement Failure
Pulling the red cord should disconnect the door from the opener and allow it to move freely. But if the garage door opener isn’t disengaging properly, the opener arm may still be “holding” the door shut.
This happens when:
- The trolley jams in the rail
- The cord wasn’t pulled fully or in the right direction
- Internal gears inside the opener are damaged
In this scenario, the garage door feels locked even though it’s technically in manual mode.
Storm or Climate Damage
In South Florida, doors take a beating from:
- Humidity and salt air, both of which can rust springs and cables
- Sudden power outages and surges
- Tropical storms or hurricanes that warp tracks and panels
- Heat and moisture that swell door sections and make them stick
If your garage door won’t open manually after a storm, then damage from wind, water, or debris is likely the cause.
What You Can Safely Check (And What You Should Never Do on Your Own)
If you’re dealing with a stuck door, here’s what you can try on your own — and what you should absolutely leave to the professionals.
Safe Things to Check:
- Fully disengage the opener. Pull the red garage door release cord firmly down and toward the door. Then try lifting the door.
- Look for visible damage. Are the garage door rollers off the track? Are the tracks bent or obstructed? Do the garage door springs look gapped, rusty, or broken?
- Test the weight. Lift the door slightly (no more than a foot) with two hands. If it feels unusually heavy, stop. That’s likely a spring issue.
What’s NOT Safe to Check:
- Don’t force the door open. If the garage door system is jammed, forcing it can bend tracks, break rollers, or cause it to fall suddenly.
- Don’t touch broken springs or cables. These parts are under extreme tension and can cause serious injury.
- Don’t attempt DIY spring adjustment. Torsion spring systems can be hazardous. Attempting to adjust them without proper tools or training can result in severe injury or death.
- Don’t operate heavy commercial garage doors manually unless they’re balanced. If the lift system has failed, even strong adults can’t safely lift large overhead doors.
How Florida’s Climate Affects Commercial and Residential Garage Doors
Here’s why manual garage door issues are especially common across Palm Beach, Broward, and Martin counties:
- Salt air accelerates corrosion on garage door springs, rollers, and cables.
- High humidity shortens spring lifespan dramatically.
- Storm surges and winds shift tracks or warp panels.
- Power outages create more emergency lift situations.
- Moisture and heat cause swelling that jams door sections.
The Commercial & Residential Impact
When a garage door gets stuck, the consequences can look different for both homes and businesses:
For businesses:
- Delivery trucks can’t access your bays
- Customers can’t reach your entry
- Your location may be left unsecured after hours
- Downtime can disrupt your operations and revenue
For homeowners:
- You may be unable to leave or enter during an outage
- Your property becomes more vulnerable to break-ins
- Heavy doors pose a hazard to kids, pets, or vehicles
Whether it’s a roll-up garage door in a warehouse or a sectional garage door at home, the solution is the same: don’t delay the repair.
How to Prevent Future Breakdowns
To avoid future garage door issues:
- Schedule yearly maintenance, especially in coastal zones
- Lubricate hinges, bearings, and spring wire — not the track
- Inspect garage door springs and cables every few months
- Replace rusted components early
- Install hurricane-rated garage doors if you’re near the coast
- Test your manual release twice a year
- Don’t ignore early warning signs like jerky motion, noisy operation, or sagging doors
Investing in preventive care is the best way to avoid costly downtime, whether at home or at work.

Frequently Asked Questions About Jammed Garage Doors
How do you open a garage door manually with a broken spring?
If your garage door won’t open manually because of a broken spring, the safest answer is: you don’t. A broken torsion or extension spring means the door has lost its counterbalance system and may weigh 200–400+ pounds. Attempting to lift it by hand can cause serious injury or cause the door to fall unexpectedly. If your garage door is too heavy to lift or you hear a loud “bang” before it stopped working, stop immediately and call a professional.
Can you manually open a garage door with no power?
Yes, as long as your springs and cables are intact. If the opener loses power, you can pull the emergency release cord to disengage the motor and then lift the door by hand. However, if your garage door won’t lift manually, even with no power, you may have a spring, cable, or track issue preventing movement.
Can you spray WD-40 on garage door rollers?
It’s best not to use WD-40 on garage door rollers. WD-40 is a solvent, not a long-term lubricant, and it can actually strip grease from bearings. Use a silicone-based or lithium-based garage door lubricant instead, especially on rollers, hinges, and springs.
What’s the average cost to replace a spring on a garage door?
In most regions, replacing a torsion or extension spring typically ranges from $150–$350, depending on door size, spring quality, labor rates, and whether it’s an emergency call. Commercial garage doors or oversized roller doors can cost more. If your garage door won’t open because of a broken spring, replacement is the required fix.
Is it bad to force open a garage door when the spring is broken?
Yes — forcing it can be dangerous. A spring’s job is to counterbalance the door’s weight. Without it, the door becomes extremely heavy and unstable.
Trying to force open a garage door with a broken spring can:
- Bend or warp the tracks
- Snap cables
- Cause the door to slam down
- Damage the opener
- Lead to severe injury
If you suspect a broken spring, stop trying to lift the door immediately.
What is the average lifespan of a garage door?
Most garage doors last 15–30 years, depending on the material (steel, fiberglass, wood), usage, and climate. Doors in coastal or humid areas — like South Florida — may wear down faster due to salt-air corrosion and increased exposure to storms. Springs themselves typically last 10,000–30,000 cycles, though they can wear out sooner in high-humidity environments.
