More about this in Thompsons

A broken garage door sensor keeps the door from closing at all, or lets it start down and then send it right back up before it reaches the floor. That's the opener refusing to finish the cycle because one of the two small sensors near the floor track isn't getting a clean signal from the other. This fault is one of several covered under emergency garage door repair Thompsons.

Call (346) 220-4724 and a crew working the Thompsons area will sort out which sensor is the problem.

Why a broken garage door sensor stops the door from closing

The two sensors sit low on either side of the track, a few inches off the slab, aimed directly at each other across the opening. When that beam is broken or misaligned, the opener treats it as an obstruction and won't let the door close, or it reverses the door mid-drop. A knocked bracket, a dirty lens, or a loose wire behind either sensor can all produce the exact same symptom, which is why the fix starts with checking both sensors before touching anything else on the door.

Close to 41% of Thompsons sits under water, most of it Smithers Lake, the cooling reservoir built for the W.A. Parish plant next door. That much open water sitting low against the surrounding land keeps humidity high around every structure in town, and that constant moisture works on unprotected sensor wiring and metal brackets faster here than in drier parts of the county. A sensor that keeps drifting out of alignment for no obvious reason is often a bracket that's started to corrode rather than a wiring fault, and that's when a broken garage door sensor call turns out to be a hardware problem, not an electrical one.

Damaged sensor on a garage door in Thompsons, TX: condo parking garage door service

Thompsons flooded fast during Hurricane Harvey when the Brazos River burst its banks, and most homes in town took on water before anyone could get out ahead of it. A garage door sensor mounted low on the track is exactly the kind of hardware that would have sat underwater during that event, and corrosion from a flood years back can still be working through a wiring connection or bracket that was never replaced. On a sensor call in Thompsons, checking whether the hardware has a flood history is part of tracking down why it keeps failing.

A broken garage door sensor on an older setup versus a newer one in Thompsons

With just 114 housing units recorded at a density of 18.4 per square mile, Thompsons is spread thin, and a fair share of its garage doors and openers have been in place for years rather than installed recently. Older sensor units and the wiring that feeds them are more likely to show corrosion or a loose connection than a sensor on a setup installed in the last few years, so age of the opener is often the first thing worth ruling in or out.

Don't keep forcing the wall button when a broken garage door sensor is blocking the close cycle — that just risks the opener trying to push the door past a safety fault it's designed to respect.
