Why Openers Reverse
Modern openers are designed to reverse if the photo-eye sensors detect something in the door's path, or if the door meets more resistance than expected while closing — a built-in safety measure required on all residential openers. If this happens consistently with nothing visibly in the way, the sensors are likely misaligned, dirty, or the opener's force and limit settings have drifted.
Never Disable the Safety Sensors
Some homeowners are tempted to unplug or bypass the sensors to stop the reversing. We strongly advise against this — the sensors exist specifically to prevent the door from closing on a person, pet, or object, and the correct fix is realignment, not removal.
Track Resistance as a Hidden Cause
If the door meets friction from a slightly bent track or worn rollers partway through its travel, the opener can misread that resistance as an obstruction and reverse. Fixing the underlying mechanical issue often resolves the reversing entirely.
