Garage Door Opener Safety Sensors: 2-Pack for Liftmaster Chamberlain 41A5034 - Replacement Garage Door Sensors

Product Information:

The package contents include 2 craftsman garage door sensors (sending and receiving), 2 screws and wing nuts, 5 round head bolts, and 1 user manual. This garage door sensor set is compatible with 1997-Current Sears Chamberlain Craftsman Master Mechanic and Wayne Dalton garage door openers, and provides a safety sensor option.

Easy to Install:

You can refer to the user manual to replace the original garage door sensors. When the sensor detects an obstacle, the yellow light sensor sends an invisible beam to the green light sensor, and the door will automatically stop closing and reverse.

Note:

Your garage door opener must be equipped with a safety sensor. If not, installing this accessory will not add the feature. Please ensure you disconnect the power from the door openers before installing.

Updated:

This replacement garage door sensors is version 2.0, which replaces the older style sensors with a plug-in wire that were prone to failure.
