What Sensor Repair & Replacement Covers
Safety sensors are the small units mounted near the bottom of your garage door tracks that detect obstructions and prevent the door from closing on a person, pet, or vehicle. In Glenelg, MD, sensors commonly fail from misalignment, dirt or moisture on the lenses, damaged wiring, or general age. Repair means realigning, cleaning, or replacing sensors so the safety system functions reliably again.
A door that reverses unexpectedly, refuses to close at all, or has a blinking light on the opener unit is almost always pointing to a sensor issue rather than the door or opener motor itself.
Why Sensor Function Matters
Beyond convenience, sensors exist specifically to prevent injury. A door that closes without detecting an obstruction underneath it is a genuine safety hazard, particularly in households with children or pets.
Sensor issues are also one of the more common reasons a garage door opener seems to "stop working" when the motor itself is actually fine.
