Garage door sensors

Sensors worked when I disconnected them! LiftMaster opener. Connected whites to 2 and blk/wht to 3. Green lites are on. The door won't stay down. I noticed that one green light goes out if I interrupt the light path between the sensors, but the other one stays on all the time. Do I need to adjust sensitivity? Recommendations please. Thx!
