Ceiling-mounted garage door opener with its rail and power cord

Replace and install garage door safety reversing sensors (photo eyes)

Safety reversing sensors are a required safety device: a beam across the opening near the floor that reverses the closing door. Replacement means matching the sensors to the opener brand, mounting both at the same height close to the floor (not more than 6 in above it), wiring them to the opener's sensor terminals and aligning them until both indicator lights are steady. Door springs and cables are BLOCKED and not part of this job.

Before you start

Unplug the opener before connecting sensor wires at the motor head.
Never bypass, jumper or mount the sensors high to get the door to close; they are required for the opener to be safe.
Springs, cables and bottom brackets are under high tension: do not loosen or adjust them (BLOCKED, refer to a trained door technician).

Car HomeLink won't program to a Security+ 2.0 (yellow LEARN) opener

Confirm the opener's radio (yellow LEARN button means Security+ 2.0), then use the vehicle's HomeLink procedure with a fresh remote battery and the 30-second LEARN window. Many older HomeLink vehicles cannot speak Security+ 2.0 and need a Chamberlain/LiftMaster HomeLink compatibility bridge.

Opener chain or belt sagging, slapping, or too tight

A loose chain slaps and can skip teeth; an overtightened chain or belt loads the motor and sprocket and can trigger faults. Set tension with the door disconnected, then run a full cycle and the reversal test.

Door stops or reverses partway while opening (often worse in cold weather)

On opening, photo eyes do not matter, so a mid-travel stop is almost always force: the opener sensed more effort than it learned. Look for a door that binds, stiff cold lubricant, ice in the track or a spring problem before touching settings. Only then reprogram travel/force.
