Garage Door Garage Door Sensor Installation Andover, MN
Garage Door Sensor Installation in Andover comes with local context. Given harsh winters with heavy snowfall and ice, brief mild summers, and severe freeze-thaw stress much of the year, the doors here see cold-thickened opener grease that bogs down the motor, ice dams that bind the bottom panel to the threshold, and doors iced to the slab on sub-zero mornings, so our garage door sensor installation work uses hardware chosen to last in Minnesota's cold northern climate.
Because Andover has harsh winters with heavy snowfall and ice, brief mild summers, and severe freeze-thaw stress much of the year, the doors here age differently than inland or coastal homes elsewhere. The usual culprits are cold-thickened opener grease that bogs down the motor, ice dams that bind the bottom panel to the threshold, and doors iced to the slab on sub-zero mornings — exactly what our techs come prepared for.
We've fixed thousands of doors around Anoka County, and the pattern holds in Andover: ice- and snow-jammed tracks, frozen, sluggish openers in unheated garages, snow-load strain on tracks and brackets, and cold-snapped torsion springs in deep winter. None of it should leave you without a working garage for more than a day.
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.
Signs you need garage door sensor installation
Door refuses to close from remote
Misaligned or dirty photo-eyes prevent close. The opener's status light usually blinks 10 times to indicate the photo-eye fault.
Door closes part-way then reverses
Photo-eyes detecting a phantom obstruction (often sun glare or insects). Realignment or shielding usually fixes.
Status light blinks 10 times
Universal LiftMaster code for photo-eye fault. Genie and Chamberlain have similar fault patterns.
Sensors visibly knocked out of alignment
Bumped brackets, lawn-equipment impacts, or vehicle contact all knock sensors out of aim. Realignment is a quick fix.
Older opener with no sensors
Pre-1993 openers don't have photo-eyes. Retrofit is possible on most models — and brings the door to current safety code.
Common causes & what we fix
Bracket misalignment
Brackets shift slightly from temperature cycling, vibration, or contact. Even a few degrees off-aim breaks the sensor beam.
Lens dirt or insects
Dust, spider webs, and insect carcasses block the infrared beam. Cleaning the lens often restores function.
Sun glare interference
Direct sunlight hitting the receiver lens can saturate the sensor and trigger false obstruction. Shielding or repositioning fixes.
Wire damage
Mice chew sensor wires; landscapers occasionally cut them. Replacement and re-routing fixes.
Sensor end-of-life
Photo-eye electronics fail at 10–15 years. Replacement is inexpensive and quick.
