Liftmaster 41a5034 Safety Sensors  Photo Cells Chamberlain (NOW 041-0136)

The LiftMaster 41A5034 are the replacement safety sensor beam infrared photo eye sensors that have a green indicator light on one side and a yellow indicator light on the other side, used on many garage door openers manufactured from 1997 to present. These garage door openers typically had a red, orange or purple learn button on the back of the garage door opener that is used to program the remotes with. The 41A5034 are the replacement sensor heads only and have a 12” wire extending from them but they DO NOT include the mounting brackets. These LiftMaster 41A5034 safety sensors are a genuine factory original part made by Chamberlain Corporation who makes the LiftMaster, Sears Craftsman, Master Mechanic, Access Master, Do-It and some of the Wayne Dalton garage door openers. A good sign that the safety sensor beams are bad provided that they are aligned is when you can open the garage door opener normally but not close it unless you hold down the wall button until the door is fully closed. The LiftMaster 41A5034 replacement safety beam kit includes one sending head, one receiving head, four easy connect connectors, 2 wing nuts with carriage bolts and instructions.

These beams have a green LED indicator on side and a yellow LED indicator on the other side.

NOTE: If your beams have a green indicator on both sides you need the LiftMaster part number 41A4373A available in our store

NOTE: The model number of the garage door opener will typically be under the light cover.
