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

A garage door sensor blinking rarely happens in a vacuum. Dallas's sustained 100°+ heat wears doors down — clay soil shifts door frames — and we get a clear run of these calls every July heat wave. A local pro fixes the underlying cause and backs it with a one-year warranty.

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 Dallas pro

We realign and clean the sensors, check the wiring, and confirm the door closes without blinking or reversing.
