How it works
Step 1
Read code
Opener blink code tells us if it's alignment, wiring, or a dead sensor.
Step 2
Align / replace
Brackets adjusted, lenses cleaned, or sensors swapped.
Step 3
Re-wire
Damaged sensor wire re-run end-to-end if continuity fails.
Step 4
Test
Three close cycles plus object-in-path safety test.
How safety sensors work
Two photo-eye sensors create an infrared beam across the opening.
Why your door suddenly stopped closing
Sensors drift — bracket loosens, bag bumps one, sun angle changes, wire staple cuts through.
