LiftMaster41a4373a Garage Door Openers Safety Sensors

Perfect match. Easy connection and works as anticipated.

The company supplied flimsy wire connectors but I chose to use my own wire nuts. Other than that everything was simple to install and works great.

This part worked exactly as expected. It took less than 10 minutes for installation and worked immediately. I am happy with its performance.

These sensors were a direct replacement for the original units. The installation was quick and simple, and they work like they are supposed to. They cost one fourth of what the local dealer quoted

The sensors are an exact match for the original and hard-to-find (y1994) Craftsman part #s with pins for plug-in connecting wires. Thanks to Chamberlain for continuing to manufacture them with an improved integral wire ends! I just needed the sending eye (emitter) to replace the original one which had a broken pin due to corrosion over the years. Worked right away. Keeping the receiving eye (receptor) as a spare, though I heard a light rattling noise when I took it out of the box (appears to have a loose component inside it). I hope it works if and when I need to replace a failed receptor.

First, the parts are branded Liftmaster and it looks exactly like the image that is shown. There are no bolts/wing nuts or mounting hardware, but your existing sensors' hardware fit perfectly.The new units have a 3-foot section of wire that needs to spliced (wiring 101) into the existing wiring. Locking connectors and easy to follow instructions are included.The new wiring has a far superior connection into the sensor vs. clip-in connector that the old sensor used (and gave me fits).

A great repair item and super fast service

My sensors on my garage door finally became too frustrating to deal with anymore. I bought the right year replacement and the install took me 10 min. I feel like I did something wrong, it was so easy. The wire connectors were amazingly easy to use. Now my garage door works like a charm.
