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.
