More about this in Sheldon

A garage door sensor not working means the door won't close at all, or it starts down and reverses back up every time, because the opener can't get a clean signal between the two sensor eyes near the floor. That's almost always a lens, alignment or wiring problem at the sensors themselves, not a failure in the opener unit overhead. This page is one part of a larger guide to garage door service Sheldon.

Call (346) 220-4724 and a crew working the Sheldon area will get the sensors reading clean again.

Why a garage door sensor not working stops the door cold

Every opener built in the last few decades is required to stop closing the moment that sensor beam is broken, so a bad sensor doesn't just cause a nuisance — it locks the whole system into a safety hold. Dust on a lens, a low-hanging cobweb, a toy left in the doorway, direct sun hitting the receiver eye at the wrong angle, or a bracket that's been bumped out of alignment can all trigger the same result: door goes down a few inches and comes right back up.

Sensor wiring runs low along the garage wall, close to the floor, which puts it right in the path of any standing water that gets into a garage. In houses where a flood reached the garage slab, corrosion at the wire connections or inside the sensor housing itself can cause exactly this symptom months or years after the water is gone — the sensor looks fine, but the signal keeps dropping.

What a garage door sensor not working call in Sheldon usually turns up

Your garage door sensor quit working in Sheldon, TX: an evening service call

Hurricane Harvey put more than 40 inches of rain on the western end of Sheldon ISD, and Greens Bayou floodwater reached C.E. King Middle and High Schools along with several densely populated neighborhoods nearby. Community leaders estimated 25 to 40 percent of homes across the district took on flood damage in that storm — the worst flood impact relative to size of any school district in the greater Houston area. A garage that sat in that water almost certainly had sensor wiring and brackets sitting in it too, which is why low-mounted electrical components are one of the first things checked on an older Sheldon property.

Rental units and a garage door sensor not working

Sheldon runs a 49 percent rental rate, well above the statewide average, and rental turnover means a sensor knocked loose or a wire chewed through by a previous tenant's storage setup can go unnoticed until a new occupant tries to close the door and it won't. With a median home age going back to 1980, a fair share of Sheldon's sensor hardware and wiring is old enough that a straightforward alignment fix isn't always the end of it — sometimes the sensor unit itself needs to come off the bracket and get replaced.
