Garage Door Sensor Installation
Photo-eye safety sensor installation, alignment, and replacement. Required by UL-325 safety code — we test auto-reverse and verify the door stops on a 1.5-inch obstruction.
Our garage door sensor installation service covers all of Los Angeles: Downtown, Hollywood, Silver Lake and West LA. Set in the Los Angeles & Orange County coastal basin, these doors face marine-layer humidity that pits uncoated springs and rollers and Santa Ana wind events that drive grit into open tracks, and we plan every repair around it.
Los Angeles sits in the Los Angeles & Orange County coastal basin — a mild Mediterranean climate where ocean-cooled mornings give way to warm, dry afternoons, with a marine layer that lingers through late spring. That puts real stress on garage door hardware: we routinely see marine-layer humidity that pits uncoated springs and rollers and Santa Ana wind events that drive grit into open tracks, and we fit parts rated to handle it.
Across Los Angeles County, the garage door problems we see again and again are broken torsion springs on high-cycle suburban doors, misaligned photo-eye sensors after seasonal grit buildup, and worn nylon rollers on doors cycled multiple times a day. If that sounds like your door, there's a good chance we can fix it today.
Photo-eye safety sensors are required by UL-325 on every garage door opener manufactured since 1993. They detect obstructions in the door's path and either reverse the door (during close) or refuse to start (when activated). When sensors are misaligned, dirty, sun-blinded, or failed, the door either refuses to close at all or — worse — closes without sensing an obstruction. Our sensor installation service replaces failed sensors, realigns drifted brackets, cleans the eye optics, and verifies auto-reverse on a real obstruction test.
Replacement eyes are brand-specific (LiftMaster has a different connector and signal pattern than Genie). We stock the major brands and most legacy models. Brackets occasionally need replacement when corrosion has degraded them or impact has bent them. Bracket alignment is critical — eyes that are slightly off-aim trigger intermittent close failures that drive homeowners crazy.
Every visit ends with an obstruction test: a 1.5-inch (3.8 cm) tall object placed under the door at three positions across the opening. The door must reverse when it touches the object. This is the UL-325 baseline — if the door doesn't pass, the install isn't complete. We document the test results on the work order.
Photo-eye electronics fail at 10–15 years. Replacement is inexpensive and quick.
