The 041-0136 Safety Sensor Kit replaces the previous model 41A5034 safety sensors.
The safety sensors on the garage door opener are there to keep the door from closing on an object, car or person. When your garage door won't close then it may just be a matter of realigning the sensors or cleaning the lens of the sensor to get them working again and get your garage door to close. When that doesn't work it's possible the sensors have failed and need to be replaced.
The new Liftmaster 041-0136 Safety Sensor Kit includes the replacement sending sensor and receiver sensor. The Liftmaster garage door sensors have pigtail wires and wire connectors so the new sensor wires can be connected to your existing safety sensor wires. The kit does not include the mounting brackets but you can reuse your existing sensor brackets if you have the brackets shown here (p/n 41A5266-3) or you can purchase compatible 041-0155 Sensor Mounting Brackets here.
