Which fix fits?

IfThe door starts to close, then reverses and the opener light blinks.

ThenPhoto-eye alignment.

The sensors near the floor are out of line or dirty; a clean and re-aim usually restores normal closing.

IfThe door touches the floor and pops back open.

ThenClose-limit adjustment.

The opener thinks it hit something; setting the travel limit correctly stops the bounce.

IfThe door closes but leaves a gap along the bottom.

ThenBottom seal and limit setting.

A compressed seal or a short travel limit leaves daylight; both are simple to correct.

IfA high-lift door begins smoothly, then a cable loses tension as the top sections change direction.

ThenCommercial Sectional Door Repair.
