41A5034 Garage Safety Sensor Kit Compatible with Liftmaster Sears Chamberlain Craftsman, Garage Door Openers Parts Replacement(1997-current), 2 Garage Door Sensors (Receiving&Sending),G801CB-P

Very detailed instructions except one VERY important point, nor does the housing & Amazon product detail pictures from seller does not indicate which item what. Troubleshooting responses from seller and others; the receiver has a green led, transmitter amber led??? Kind of useless directive, until taking the time to wire aka power the item.This sensor works well on my chamberlain door opener, this is my second purchase because the 5 y/o OEM in 2023 failed. I was lucky then, happened to pull the right one out of the box, 5 minutes later back in business - door worked perfectly. Enter in 2025, puppy helping me in the garage, in a split second when I was working on something, I heard her.. too late, sensor broken. Unfortunately it was the same one as replaced in 2023, so I ordered the new one. But nothing on the housing or searching simply said what I put on the pictures above until wiring it to see the LED color to install the proper item.These are 2 different sensors and you do not need to install both, saw that in the Q’s too. Save that other for another day of puppy life or just plain wearing out 😉

Great price and product. My sensors faulted after 20 years. These were easy to install and setup!! So far working great!

Worked great and came with everything you need.

Worked just fine but didn't use the supplied wire connectors they would not hold wire tight.

Works great. Easy to install

Assuming these continue to work, these are a perfect replacement for a failed sensor. I actually like that these only come with a short bit of connection wire and that you have to use a separate wire to make the run to the garage door opener. I had to replace an existing sensor not because the sensor was bad, but because the wire had gotten brittle and was making intermittent connection, so I was going to have to get new wire anyway.2 of my sensors are in a place where they can get wet, so if one does fail because it gets too wet I won't have to rerun the wire again.The sensors come with simple clear instructions and little connectors so safely "splice" the pigtail with whatever wire you use to run to the opener. They fit perfectly in the brackets I already had.

Exact replacement, easy to install and worked correctly right away

Works great. Only installed for one day so far but looks like the perfect replacement. Time will tell. There has been some discussion on non-5 star reviews that it's impossible to tell which is the sending or receiving unit. While it may be impossible to tell by looking at the LED without power, if you look at the eye of each one, they are different. One is rounded (this is green) and one is flat (this is amber). Easiest and surest method - before you remove the old ones note which unit has the rounded eye and which one is flat. Then, simply swap them out for the correct one.
