Garage Door Won’t Close? Five Checks for Florida Garages

You press the remote, the door starts down, then stops and climbs back up. Or it sits there while the opener light flashes. Around Tampa Bay this is one of the top reasons people call us. Usually it's the safety sensors, which you can often fix yourself in minutes.

1. Check the sensor lights

Openers built since 1993 carry two photo-eye sensors, about six inches above the slab on either side of the opening. One sends an invisible beam, the other receives it, and while that beam is blocked the door won't travel down. In a Florida garage it's often a beach chair, cooler or pool float. If the path is clear, the bracket may have been bumped. The receiving eye's LED should glow steady; if it blinks or stays dark, loosen the wing nut, turn the sensor until the light holds, and retighten.

2. Clean off film, pollen and webs

Spider webs, spring oak pollen, sprinkler spray and coastal salt haze can blind a lens as surely as a box in the doorway. Wipe both lenses with a soft, dry cloth.

3. Watch for late-day sun

If your garage faces west, evening sun can shine straight into the receiving eye and drown out the beam, so the door refuses to close until sunset. A small sun shield over the receiver, or swapping the two eyes so the receiver sits on the shaded side, usually ends it.

4. Inspect the tracks and rollers

With the door raised, look down each vertical track from inside. A dropped tool, storm debris, a bumper dent, or rust from our humidity can catch the door partway or make a roller bind. Don't push the door past a snag.

5. Leave the force setting for last

The opener's close-force adjustment can drift. Too sensitive, and it mistakes ordinary drag for something in the way. But it's a safety control: turned up too far, the door presses down on whatever is under it instead of backing off. If the first four checks didn't solve it, stop and give us a call.

When it's not the sensors

A door that reverses at the same height every time, or drops hard onto the floor, points to balance or a worn lift cable. Summer lightning can also damage an opener's circuit board or sensor wiring. Both need a technician, and in hurricane season don't wait: a door stuck open during a storm leaves the garage exposed.
