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

Why does this keep happening in Bellingham? A lot of it comes down to the local climate. Constant damp and cold mornings takes its toll — damp air rusts springs & cables, and moisture warps wood & seals — so a garage door sensor blinking is one of the more common calls our Bellingham crews run.

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 Bellingham pro
