The photo-eyes stop your door from closing on a child, a pet or a car. Holding your wall control to force your door down overrides them, so stop doing it and keep your opening clear until the safety loop works again.

Garage Door Sensor Problems in Euless, TX
Your garage door starts down and reverses to the top, or it closes only while you hold the wall control. Garage door sensor problems mean the safety photo-eyes at the base of each track have lost their signal, from a knocked mount, a clouded lens, damaged wiring or low sun shining into one lens. Keep the opening clear and call about the sensors at your Euless garage.
What you are seeing
What sensor faults look like from the garage floor
The photo-eyes sit low on each side of your opening, and each carries a small indicator lamp. When one loses the other's signal, your logic board blocks the close command.
- Reverses at the start
The door travels a few inches down and climbs back to the top.
- Closes only while held
Holding your wall control overrides the photo-eyes, the clearest sign of a sensor fault.
- Dark or flickering lamp
One indicator lamp goes out or flickers, marking an eye out of line or a wiring break.
- Flashing motor-head light
The opener light flashes a fault pattern for a broken safety loop.
- Afternoon-only fault
The door reverses when low sun hits one lens and closes normally after dark.
Safety protocol
Never close the door on overridden sensors
Keep kids, pets and cars out of the opening, and call before anyone holds the wall control to force the door shut.

What a sensor fault puts at risk
A sensor fault either leaves your garage open or tempts someone to override the system that stops your door before contact.
- Crushing hazard
A door closed with the photo-eyes overridden can come down on whoever walks under it.
- Garage open overnight
A door that reverses on every try stays open to the street.
- Strain on the drive
Repeated reversals load the drive gear and your door arm at each change of direction.
- Spreading short
A nicked low-voltage wire along the wall can short back into your logic board.
Property type
Why the fault comes and goes with the sun
A photo-eye reads a narrow infrared signal, and strong low sun aimed straight into the receiving lens can drown it. If your Euless garage faces west, your door can reverse every late afternoon and close normally by evening.
Glare calls for a lens shield or moving the receiving eye to the shaded side of your opening, and garage door sensor alignment then squares both eyes across the doorway.
Local detail
Bumped photo-eyes in a crowded Euless garage
A garage that holds bikes, mowers and bins puts the photo-eyes in the path of everything that rolls in and out. If one lamp went dark after something bumped it, leave the door where it is and call about the mount.
Repair scope
How sensor service restores the safety loop
Sensor work starts at the indicator lamps and follows the fault through the mounts, the eyes and the wire back to the motor head.
- Bracket repair
Solid mounts replace brackets a bumper, a mower or a bike knocked out of line.
- Lens and housing
New eyes replace cracked housings and clouded lenses.
- Low-voltage wiring
Tracing runs the wire end to end to find nicks, staples through the jacket or chewed spots.
- Safety sensor realignment
Both eyes sit at matching height, square to each other, with steady lamps.
- Reversing test
The door must reverse on an object at the floor and whenever anything crosses the eyes.
Service sequence
From a reversing door to a safe close
Bay kept clear
You stop overriding the eyes and keep people out of the doorway.
Fault located
Lamps, mounts, lenses and wiring show which side lost the signal.
Eyes restored
Repaired mounts, new eyes or new wire bring the safety loop back.
Close proven
Your door closes with no one holding the wall control and reverses when anything crosses its path.
Triage order
Why a sensor fault calls for a call, not a workaround
A door that only closes while held is a door with its safety system switched off. Keep the opening clear and call from Euless or another Tarrant County city before the workaround becomes habit.

Common questions
Sensor answers
Why does the garage door go back up as soon as it starts down?
The logic board checks the photo-eyes before it closes. When one eye loses the other's signal, the close command stops and the door returns to the top. Call about the sensors rather than holding the wall control.
Is holding the wall control a safe way to close the door?
No. It overrides the one system that stops the door on a person or a pet. Keep the opening clear and call instead.
What does a flickering indicator lamp mean?
A lamp that flickers or goes dark points at an eye knocked out of line, a failing eye or a break in its wire.
A door held by a broken spring is a door waiting to drop.
Call from Euless before a broken spring or cable strips the opener or bends the sections.
