Garage Door Sensor Repair in Indianapolis

If your garage door starts to close and then immediately reverses back open, or won't close at all while the light on the opener blinks, the safety sensors near the bottom of the track are almost always the cause. These small sensors sit a few inches off the ground on either side of the door and use an infrared beam to detect anything in the door's path — a required safety feature on every modern residential opener.

Sensor problems are usually simple: they've been bumped out of alignment, something is blocking the beam, or a lens has gotten dirty or fogged. Occasionally the issue is a wiring problem or a failed sensor unit itself, which needs actual replacement rather than realignment.
