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

In Rock Hill, the weather is often part of the story behind a garage door sensor blinking. Months of heat and humidity mean humidity corrodes hardware and falling limbs dent panels across York 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 Rock Hill pro
