What's the most common reason a garage door won't open?

In our experience across San Francisco, a broken torsion spring tops the list by a wide margin, followed by stripped opener drive gears and simple control problems like a locked wall console or dead remote battery. The spring case has a tell: the opener runs, strains, and gives up, and the door feels impossibly heavy if you try lifting it by hand.

What will it cost to figure out what's wrong?

Our diagnostic visit runs $45–$95 depending on time of day, and we credit it in full against whatever repair you approve. So if the problem turns out to be a $180 spring, you pay for the spring, not the spring plus a diagnosis. You'll have an exact all-in number before we start.

The wall button works but my remotes don't. What does that mean?

That pattern points away from the door and toward the radio side: a locked-out receiver (many wall consoles have a lock button that's easy to press by accident), remotes that lost their programming after a power blink, or a failing receiver board. It's usually one of the cheapest fixes on the list — often solved in a single short visit.

Is it safe to force the door open to get my car out?

If the spring is broken, no — the door can drop the moment you let go, and doors on steep SF driveways add their own hazard when there's nothing holding them. If you must get out before we arrive, call us first at (415) 494-4774 and we'll talk you through checking whether it's safe to release the opener and lift, and how many people it takes to do it without injury.

Do you charge extra for night or weekend calls?

Our 24/7 coverage is genuine — a 2 a.m. call gets a technician, not an answering service promising a morning slot. After-hours diagnostic pricing sits at the upper end of the $45–$95 range, and repair pricing itself doesn't change based on the clock. The quote you approve is the full price.

Why Won't My Garage Door Open?

A garage door that won’t open can stem from several different issues. Understanding the potential causes helps you know when to attempt a simple fix versus when to call a professional.

Common Causes of Garage Doors That Won't Open:

Broken Torsion Springs

The most frequent culprit is a snapped torsion spring. These springs bear the entire weight of your door sometimes up to 400 pounds or more. When one breaks, you’ll typically hear a loud bang and the door becomes impossible to lift manually. Never attempt to operate a door with broken springs, as this creates serious safety risks.

Disconnected Opener

Your garage door opener may have become disconnected from the trolley. This often happens accidentally when someone pulls the emergency release cord. Look for a red handle hanging from the opener track—if it’s been pulled, your opener can’t engage the door.

Power Supply Issues

Sometimes the simplest explanation is the right one. Check if your opener has power. Look for:

A tripped circuit breaker
An unplugged power cord
A burned-out outlet
GFCI outlet that needs resetting

Damaged or Frayed Cables

Lift cables work alongside springs to raise your door. If cables are frayed, twisted, or broken, the door won’t operate properly. You might notice the door hanging unevenly or cables hanging loose on one side.

Broken Gears in the Opener

Belt-drive and chain-drive openers use plastic gears that can strip over time. If you hear the motor running but the door doesn’t move, this could be your issue.

Locked Door Track

Some garage doors have a manual lock mechanism that can engage accidentally. Check for a handle or lever on the inside of the door that may have locked the door in place.

Can I Fix It Myself?

Some garage door issues are safe for DIY troubleshooting, while others require professional expertise.

Safe DIY Checks:

Reconnect the trolley - Pull the emergency release cord when the door is fully closed, then manually lift the door. The trolley should reconnect automatically.
Check the power - Verify your opener is plugged in and the circuit breaker hasn't tripped.
Replace the batteries in your remote control or wall button.
Clear obstructions - Look for items blocking the door's path or sensor beams.

When to Call a Professional:

⚠️ Never attempt these repairs yourself:

Spring replacement – Torsion springs are under extreme tension and can cause severe injury or death if handled improperly
Cable repair – Cables work in conjunction with springs and carry similar dangers
Track realignment – Improper adjustments can cause the door to fall
Opener motor replacement – Requires electrical knowledge and proper calibration.

At Alfonso Garage Door, our technicians have specialized tools and training to handle these dangerous repairs safely.

What to Do Right Now If Your Garage Door Won't Open

Follow these steps in order:

Step 1: Stop trying to open the door Repeated attempts can damage the opener motor or other components, leading to more expensive repairs.
Step 2: Inspect visually Look for obvious issues like broken springs (you'll see a gap in the spring coil) or cables hanging loose.
Step 3: Check your opener Is it getting power? Does the motor run when you press the button?
Step 4: Test the manual release Pull the emergency release cord and try to manually lift the door. If it won't budge or feels extremely heavy, you likely have a spring problem.
Step 5: Call a professional — contact Alfonso Garage Door at (415) 494-4774 for expert diagnosis and repair.

Our Expert Technicians

Safety is Our Top Priority

We adhere to the highest industry standards for safety. A broken spring repair is dangerous, and we take that risk seriously.

We follow all DASMA Garage Door Safety Guidelines on every job.
Our safety protocols and training are aligned with OSHA Safety Standards to protect both our technicians and your property.

A Seasonal Warning for Homeowners

Cold weather often leads to more garage door spring failures, and we see a sharp increase in repair calls each winter. This is because the cold metal of the spring becomes more brittle and is under increased strain. The molecules in the steel contract, making the spring less flexible and more susceptible to snapping under the immense tension. If your spring is more than 7-10 years old, winter is the most likely time for it to break.

Frequently Asked Questions

Can I manually open my garage door if the opener stops working?

Yes, but only if the springs are intact. Pull the red emergency release cord and manually lift the door. If it's extremely heavy or won't budge, the springs are likely broken, do not force it.

How do I know if my springs are broken?

You'll typically hear a loud bang when they break. Visually, you'll see a gap in the spring coil. The door will be extremely heavy to lift manually or won't open at all.

Is it dangerous to use a garage door with one broken spring?

Extremely dangerous. The door can fall unexpectedly, causing serious injury or property damage. Never operate a door with broken springs.

How long do garage door springs last?

Standard springs last 7,000-10,000 cycles (about 7-10 years for average use). High-cycle springs can last 20,000-30,000 cycles or more.

Can cold weather prevent my garage door from opening?

Yes. Cold temperatures can cause lubricant to thicken, metal to contract, and weather stripping to freeze to the floor. Most of these are temporary issues that resolve as temperatures rise.
