Garage door sensors

tbrennan917June 16, 2012

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!

There is no sensitivity adjustment for the sensors. The lights are working correctly. Does the main light in the motor unit flash 10 times when the door reverses? What was your original problem?
