Why the door bounces back
Two small sensors sit a few inches above the floor on either side of the door, one sending an invisible beam to the other. If the beam is blocked, or the sensors get knocked out of line by a bike, a broom, or a kid’s scooter, the opener assumes something is in the way and reverses. The door is doing its job.
Try this first
Wipe both lenses and look at the small lights on each sensor. Steady lights mean they can see each other. A blinking or dark light means they can’t. Nudge the blinking one until its light holds steady. That fixes it more often than not, and we’re happy to walk you through it over the phone at no charge.
When it needs us
Sun glare, damaged wiring, or a failed sensor needs a visit. Realignment or replacement, plus a reversal test with a board on the floor, runs $95 to $150.
