This is the most common call we get, and a good share of them are resolved on the phone. Work through these in order.
1. The safety sensors (most likely)
If the door starts down and reverses, or will not start at all while the Garage Door Opener light blinks, check the two sensors near the floor. Both LEDs should be solid. A blinking LED means they are not seeing each other — realign until steady.
2. Something in the beam
A bin, a bike wheel, a coiled hose, even a large cobweb across a lens. Look along the beam path, not just at the sensors.
3. Dirty lenses
Florida garages get dusty. Wipe both lenses with a soft dry cloth.
4. The close-force setting
If the door closes most of the way then reverses with the sensors solid, the down-force limit is set too sensitively, or something is binding in the last stretch of travel.
5. Track obstruction or a bent track
Look along both vertical tracks for dents. A door that binds at the same point every time is mechanical, not electronic.
| Symptom | Most likely cause |
|---|---|
| Reverses immediately after starting down | Sensors misaligned or blocked |
| Closes most of the way, then reverses | Down-force setting, or binding near the floor |
| Will not move, opener light blinks | Sensor circuit — check wiring and alignment |
| Closes only if you hold the wall button | Sensor fault confirmed — hold-to-close is the bypass |
| Binds at the same height every time | Bent track or failed roller |
Holding the wall button will force most doors closed. If that works, your sensors are the fault — and it is a bypass for getting the door shut, not a fix to live with.

Never leave the sensors disconnected or taped facing each other. That is the system that stops the door closing on someone.
How to think about a door that is misbehaving
Garage doors are surprisingly good at describing their own faults, if you know how to listen.
Worth saying plainly. The sound it makes, where in the travel it happens, and whether it repeats — those three things narrow it down enormously.
A fault that happens at exactly the same point every cycle is mechanical. One that comes and goes is usually electrical or environmental. It is a small thing that turns into a big thing.
The five-minute triage anyone can do
Start with the wall button. If the wall button works and the remote does not, the fault is on the radio side — battery, pairing or interference.
It sounds obvious. It is not. If neither works, it is power, the safety circuit, or the Garage Door Opener itself.
If both work but the door will not move, it is mechanical, and it is very often a spring.
That one test splits the problem in half before anyone has picked up a tool. Nobody enjoys hearing it, but it saves money.
The order we work through it
Every visit runs the same way, whatever the original complaint was. It is quicker than it sounds, and it stops us treating a symptom and calling it a fix.
- Balance first, by hand, opener disconnected. It rules half of everything in or out.
- Then the safety circuit — sensors, alignment, lenses, wiring.
- Then the tracks, along the full height, looking for the point where it binds.
- Then rollers and hinges for play, flat spots and seized bearings.
- The opener comes last, because it is usually the victim rather than the cause.
If something on that list is worn but not urgent, we say so and give you a rough idea how long it has left. That way you can plan instead of react. That is not a sales line. It is just how the hardware behaves.
The mistake we see most
Pressing the button again. And again.
Let us be honest about this bit. If a door has stopped, something stopped it. Every further attempt drives the fault deeper — bending a track, chewing a drive gear, pulling a cable off its drum.
One fault becomes three, and a modest repair becomes a long afternoon. You will notice it long before it becomes urgent, if you know to look.
The short version
If you take one thing away from all of that: a door that is balanced, lubricated and has working safety reverses will outlast one that is not. By years, not months.
Almost everything we get called out to was preventable. Most of it was cheap to prevent, too.
So if any of this sounds like your door, get eyes on it while it is still an inconvenience rather than a breakdown. We would rather do the small job.
