More about this in San Leon

A garage door sensor won't close the door when the beam between the two small units near the floor is blocked, misaligned, or corroded, and the opener reads that as an obstruction every time. The door stops partway down or reverses back up until the sensors are aligned, cleaned, or replaced. A fuller picture of emergency garage door repair San Leon sits one level up from this page.

Why a garage door sensor won't close the door at all

The two sensors mount a few inches off the slab, one on each side, aimed directly at each other so the opener can confirm nothing is in the door's path before it finishes closing. Anything that breaks that line — dust, a bent bracket, corrosion on the contacts, or a lens knocked out of alignment — tells the opener to stop or reverse rather than finish the cycle. That's true whether the door is a year old or original to the house.

San Leon took extensive damage from Hurricane Ike on September 13, 2008, and the local post office was damaged in that storm and never replaced.

Don't keep forcing the opener when a garage door sensor won't close

Holding the wall button down to force the door past a blocked or failing sensor defeats the reason the sensor is there in the first place.
