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

In Concord, the weather is often part of the story behind a garage door sensor blinking. Months of coastal salt air and inland heat mean salt air corrodes hardware and daily use wears rollers across Contra Costa County — exactly the kind of wear a local tech knows to check first.

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 Concord pro
