Garage Door Garage Door Sensor Installation Knoxville, IA
We run garage door sensor installation across Colonial Terrace Mobile Home Park and the surrounding Knoxville area and the wider Marion County area — quick turnaround when you call early, flat-rate always, and guaranteed for ten years.
Ask any Knoxville tech and they'll tell you the climate decides what fails. Warm, wet summers and cold winters with snow and ice, driving repeated freeze-thaw cycles on exterior hardware brings wide seasonal swings that work bolts loose over time, spring damp that rusts unsealed cables and brackets, and winter snow and ice load on doors and tracks, year after year.
Run down the service log for Knoxville and the same repairs repeat: ice- and snow-jammed tracks, cold-snapped torsion springs in deep winter, freeze-thaw-cracked bottom seals, and humidity-swollen wood doors in summer. We carry every part needed to close them out in one trip.
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.
