Garage Door Won't Open in Millbrae? Here's What to Check First
2026-05-21 7 min read
A garage door that won't open is more than an inconvenience. It traps your car, blocks your workspace, and leaves you stranded. In our years serving Millbrae, we've seen this problem again and again, and the fix often depends on one simple thing: whether the door is truly broken or just needs a reset.
Why Your Garage Door Won't Open
Before you panic or reach for your phone, understand that "won't open" covers several scenarios. Your opener might have power but the door stays stuck. The remote could be dead while the wall button works fine. Or nothing responds at all. Each points to a different culprit.
The most common causes fall into three categories: power issues, sensor problems, and mechanical failure. A tripped circuit breaker or unplugged opener explains 40 percent of calls we get. Dirty or misaligned safety sensors account for another 30 percent. The remaining cases involve broken springs, cable damage, or a locked manual release that someone forgot about.
Start With These Quick Troubleshooting Steps
First, check power. Walk to your garage and look at the opener unit mounted on the ceiling. Is the indicator light on? If not, check your breaker panel. A tripped breaker is an easy fix. Flip it back and test the door again.
Next, examine the safety sensors. These sit on each side of the garage door opening, about six inches from the floor. Look for dust, spider webs, or anything blocking the beam between them. Wipe each lens clean with a soft cloth. Misaligned sensors won't let the door operate as a safety measure, which is actually the system working correctly.
Try your wall button. If it works but the remote doesn't, your remote batteries are likely dead. Replace them and test again. If neither the button nor remote works, you're dealing with an opener issue that needs professional attention.
Check for a manual release. Your opener has a red cord or lever hanging from the rail. If someone pulled it to open the door manually during a power outage, the door stays disconnected from the opener. Push the door up manually, then pull the release handle back toward the opener to reconnect it.

When DIY Troubleshooting Isn't Enough
If those steps don't work, the problem sits deeper. Broken springs, damaged cables, or a malfunctioning opener motor require professional expertise. Attempting to force a stuck door or replace springs yourself creates serious injury risk. Garage door springs operate under immense tension, and one mistake can cause permanent harm.

A stuck door sometimes points to a larger maintenance problem too. Regular tune-ups catch worn parts before they fail completely. If you've been skipping maintenance, your door might be telling you it's time. Learn more about avoiding expensive repairs through preventative care.

Frequently Asked Questions
How long do garage door springs last? Garage door springs typically last 7 to 9 years with normal use. Coastal climates like Millbrae's can shorten that lifespan due to salt air corrosion. Regular maintenance extends their life.
Can I open my garage door manually if the opener is broken? Yes. Most doors can be lifted manually by disengaging the opener using the red emergency release cord. The door should move smoothly. If it's very heavy or stuck, don't force it, as springs may be broken.
How much does garage door repair cost near me? Repair costs vary widely. Simple fixes like sensor cleaning run $75 to $100. Motor replacement costs $250 to $400. Spring replacement is $300 to $500 per spring. Get a free estimate for your specific problem.
Why won't my garage door open even though the opener is running? If the opener motor runs but the door doesn't move, suspect broken springs, cable damage, or a disconnected manual release. These require professional repair and shouldn't be attempted alone.
What should I do if my garage door gets stuck in the cold? Cold weather can thicken lubricant and cause doors to stick. Try warming the garage with a space heater for 30 minutes. If it still won't open, call for same-day emergency repair service.
