Steps
Place a solid object (commonly a 2x4 laid flat) in the door's path on the floor and initiate a close cycle
Confirm the door reverses immediately on contact with the object rather than continuing to close or stalling against it
Test the photo-eye sensors by breaking the beam with an object during a close cycle and confirming the door reverses without contact
Visually check photo-eye alignment and mounting for damage or drift
If either test fails, take the opener out of service and adjust or repair it per the manufacturer's manual before returning it to use
Known gotchas
A door that fails the reversal test should not be used until fixed — this is a recognized life-safety failure mode, not a minor nuisance
Photo-eye testing does not substitute for the physical contact-reversal test, and vice versa — both entrapment-protection paths should be checked monthly
