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.

Garage door reverses or will not close (safety sensors)

Nearly always the photo-eye safety sensors: blocked, misaligned, sun-blinded or miswired. Sensors must be repaired, never bypassed. If sensors are fine, look at force/limits and door binding.
