Inspect both sensor paths
We check alignment, indicator lights, brackets, lenses, wiring, connections, and obstructions.
Test reversal protection
Photo-eye response and automatic reversal are tested as part of the complete opener safety system.
Correct the real cause
Sensor symptoms can also involve travel limits, force settings, controls, or door movement.
Entrapment protection
A door that reverses or refuses to close may be responding to a safety fault.
Photo eyes help detect an obstruction across the opening. Alignment, lenses, brackets, wiring, connections, sunlight, travel settings, force settings, controls, and mechanical door movement can all affect closing behavior.
Door reverses
The opener may see an obstruction or respond to limits, force, or mechanical resistance.
Door will not close
Safety input, control, wiring, sunlight, or door-travel problems may be preventing movement.
Intermittent behavior
Loose brackets, vibration, wiring faults, glare, or marginal alignment can come and go.
How the safety system is checked
Sensor work should end with a complete closing and reversal test.
Inspect the path
Check both lenses, brackets, lights, wiring routes, connections, and the opening.
Correct the fault
Align, secure, clean, reconnect, repair, or replace compatible components as needed.
Test protection
Verify photo-eye response, automatic reversal, travel, force, and normal controls.
Do not defeat the sensors
A temporary workaround can remove an essential layer of protection.
Do not permanently bypass, relocate, or disable photo eyes to force a door closed. If the garage must be secured, contact LGA Garage Door for safe operating guidance and service options.
Correct a sensor or closing problem
Describe the indicator lights, door movement, and anything that changed before the issue began.
