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

In Bethlehem, the weather is often part of the story behind a garage door sensor blinking. Months of freezing winters mean cold snaps brittle springs and road salt corrodes hardware across Northampton County — exactly the kind of wear a local tech knows to check first.

What might be wrong

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

A dusty lens or direct sun can break the beam.
