Your garage door won't open, and you're stuck. In our years serving San Jose, we've seen this problem again and again. Before you panic or assume you need an expensive replacement, there are five issues you can troubleshoot yourself. Some take five minutes. Others will tell you exactly what to budget for when you call a professional.
Start here because it costs nothing and solves the problem in 20 percent of calls we receive. Replace the batteries in your remote. Dead batteries are the single most common reason a door won't respond, yet homeowners skip this step and assume the whole system is broken.
If the remote still doesn't work, try the wall button inside your garage. If that button opens the door, your remote batteries or receiver are the issue. If the wall button also fails to open the door, you've narrowed it down to the opener itself or the door's mechanical components.
Test both the up and down buttons. A door that won't open but will close (or vice versa) tells us something different than a door that does nothing at all.
Modern garage door openers have safety sensors called photo eyes mounted on both sides of the door frame, about six inches above the floor. These infrared sensors detect objects in the door's path and prevent it from closing on a person, pet, or car. When they're misaligned or blocked, the door won't open as a safety measure.
Look for dirt, spider webs, or condensation on the sensor lenses. Clean them gently with a soft cloth. If the sensors are misaligned, you'll see a blinking light on the opener. Realigning them usually requires loosening a bracket screw and adjusting the angle until both sensor lights are steady green.
This is one of the most common fixes, and it's free if you do it yourself.

Walk outside and visually inspect the door itself. Look for dents, bent sections, or tracks that are clearly out of alignment. A bent track can catch the rollers and stop the door mid-travel. Dents in the panels don't always prevent opening, but severe ones can twist the frame enough to jam the mechanism.
Check that nothing is physically blocking the door's path. Boxes, tools, or parked vehicles directly under the opening are surprisingly common culprits. Move anything within two feet of the door on both sides.
If the door looks fine but won't budge, the issue is likely in the springs, cables, or opener mechanism itself. That's when you need professional help. Springs are under extreme tension and can cause serious injury if mishandled. Don't attempt to repair them yourself.
Most garage door openers have a red cord or handle that disconnects the door from the motorized mechanism, allowing you to operate it manually. Pull this cord and try lifting the door by hand. A properly balanced door should open smoothly with minimal effort. If it's extremely heavy or won't budge, your springs are likely broken or severely weakened.
Listen carefully when the opener tries to run. A grinding noise suggests the opener motor is working but something mechanical is jammed. A clicking sound without motor engagement means the opener isn't receiving power or the circuit board has failed. Silence means no power is reaching the unit.
These sounds tell an experienced technician exactly what needs repair and help calculate the cost. Document what you hear and describe it when you call.
Confirm the opener is plugged in and the outlet has power. Plug a lamp into the same outlet to verify electricity is flowing. Tripped circuit breakers are common, especially after storms in the San Jose area. Check your electrical panel and reset any breaker labeled for the garage.
If the outlet is dead and resetting the breaker doesn't help, you may have a wiring issue. This requires a licensed electrician. For more on maintaining your entire system, read our seasonal tune-up guide to prevent future breakdowns.

Why won't my garage door open even though the motor is running? The motor may be working but the door is mechanically jammed. Check for bent tracks, broken springs, or objects blocking the path. If everything looks clear, the opener's internal gears may be stripped and need replacement.
Can I fix a garage door that's stuck myself? Simple fixes like cleaning photo eyes or replacing remote batteries are safe. Never attempt to repair springs, cables, or the opener mechanism yourself. These components are under dangerous tension and can cause serious injury.
How long does a garage door repair typically take? Most repairs take 30 minutes to two hours depending on the issue. Spring replacement takes longer than sensor adjustment. Our technicians will give you an accurate timeline after diagnosis.
What's the difference between a stuck door and one that won't open? A stuck door may be partially closed or visibly jammed. A door that won't open doesn't respond to any command. Stuck doors often involve mechanical obstruction. Won't-open doors typically point to power, sensor, or opener issues.
Should I replace my door or repair it? If the door itself is severely damaged but the opener works fine, repair is usually cheaper. If the opener is failing and the door is old, replacement may make sense. We can advise after inspection.
