I get more emergency calls about garage doors that won’t open or close than any other issue. As someone who’s spent years servicing garage doors across San Diego County, I can tell you that most of these problems have simple solutions you can try before calling for help.
Let me walk you through the exact troubleshooting steps I use when diagnosing these issues. I’ve resolved hundreds of these situations for homeowners throughout Clairemont, La Jolla, and beyond.
Check the Obvious Culprits First
Before you panic, verify that your remote has working batteries and that your garage door opener is plugged in. I know this sounds basic, but I’ve driven across San Diego only to find an unplugged opener or a tripped circuit breaker.
Also check if the wall button inside your garage works. If it operates the door but your remote doesn’t, you’ve isolated the problem to the remote itself, not the door system.
Why Won’t My Garage Door Open Even Though the Opener Runs?
If you hear the motor running but the door doesn’t move, the trolley carriage has likely disconnected from the opener. This happens when someone pulls the emergency release cord, which disengages the automatic system.
Look for a red cord hanging from your opener track. Pull it toward the motor to re-engage the trolley. Then manually lift the door slightly to help the mechanism catch, and try the opener again.

Inspect Your Photo-Eye Sensors
Misaligned or dirty sensors are the number one reason garage doors won’t close in my experience. These safety sensors sit about six inches off the floor on each side of your door opening.
Check if small LED lights on each sensor are glowing. If they’re blinking or off, the sensors aren’t communicating properly. Wipe them clean with a dry cloth, as dust and spider webs frequently block the beam.
Make sure nothing is obstructing the sensor path. I’ve found everything from toys to trash cans blocking the invisible beam between sensors at homes throughout Mira Mesa and Kearny Mesa.
Look for Broken Springs or Cables
If your door won’t budge and the opener sounds strained, you might have a broken spring. Disconnect the opener using the emergency release, then try manually lifting the door a few feet.
A properly balanced door should stay in place when you let go. If it crashes down, your springs have likely failed. You’ll also notice a visible gap in a torsion spring mounted above the door.
Never attempt to replace garage door springs yourself. These components store extreme tension and have caused serious injuries. This is one repair where you absolutely need professional help.
Check the Travel Limit Settings
Sometimes your opener’s limit settings get knocked out of adjustment, causing the door to reverse immediately or stop before fully closing. This happens more often in Southern California during Santa Ana winds when doors get buffeted.
Most openers have adjustment dials or buttons labeled “up limit” and “down limit” on the motor unit. Small adjustments to these settings can resolve reversal issues, but consult your owner’s manual for specific instructions.
Examine the Tracks and Rollers
Bent tracks or worn rollers can prevent smooth operation. I see this frequently in older San Diego homes where the door has been operating for 15 or 20 years without service.
Look along both tracks for visible bends, gaps, or obstructions. Check that rollers aren’t cracked or hanging loosely. While you can straighten minor track bends with a rubber mallet, significant damage requires professional attention. Regular Garage Door Maintenance Service can prevent many of these issues from developing in the first place.
