A blinking garage door sensor in Alexandria almost always means the two photo-eyes aren't seeing each other. It's usually a quick alignment or cleaning.

There's a local angle to a garage door sensor blinking in Alexandria: the area's freezing winters is hard on garage doors — cold snaps brittle springs, and snow & ice jam tracks. Our Alexandria techs see these failures spike around every January cold snap, so they track down the real cause instead of masking the symptom.

What might be wrong

Common causes when your garage door sensor blinking

Here's what our local techs check first — and what each one usually means.

Misalignment

A bumped bracket throws the sensors out of line and they start blinking.

Dirt or sun glare on the lens

A dusty lens or direct sun can break the beam.

A damaged sensor wire

A pinched or chewed wire interrupts the signal.

How we fix it

Fixed fast by a local Alexandria pro
