41A5034 Safety Sensor Eyes Only, Compatible with Craftsman Liftmaster Sears Chamberlain Garage Door Openers After 1997, Garage Door Sensor Replacement Kit

These worked out- I was gambling since the liftmaster was from Aug 1997, and the instruction manual parts indicated 41A4373A for the safety sensor kit, There was no reference in the item description for that part number, and I just wanted people in the same situation to know that they can save the $20+ by getting these over the item that is described as a direct 41A4373A replacement. You do need to switch the wires' coding during connection as everyone else noted, and the brackets we had were on the same side as the LED, which blocked it a bit, but you can still marginally see the light status. As for the push and pray wire connectors, you do need a strong finger push or better yet a pair of pliers to get the connector landed all the way home on the wires, or they will pull out. Use the tips of your strippers to get that orange button seated into the clear body all the way. Good stuff to save my 25 +yr old opener on an 18X7 heavy door. Problem was repeated failure to close especially on cold mornings. door would cycle rapidly at various points of travel and return to open, blinking light, to indicate safety sensor circuit issues. 41A4373A only had 1 green LED on each side that would do nothing to indicate activation, this set has an effective indicator so that you can align the beam/receivers.

I just installed my new garage door sensors, and they work great. One sensor is in direct sunlight in the morning and there was no issue there. Installation was pretty easy. Two things you need to know. First, wire them backwards as all the other reviews have stated. I have no idea why, but that's how it works. Second, get a couple of small wire nuts because the connectors supplied aren't great. You can use them, but you'll thank me later if you use wire nuts. One more thing to keep in mind is that they work for garage door openers built 1997 to present. I bought the double set of sensors and 2 and of course one my openers was manufactured in 1993 so it didn't work, but that's 100% on me. So I have an extra set if anyone wants it LOL. I like the brackets that are included because they clip right onto the tracks. No need to screw/bolt into the wall like the old ones. Most of the sensors sold on Amazon don't include the brackets. Well worth it.

If I could give 0 stars I would. I’m a professional garage door repair tech and I am very disappointed with this product and seller. I got these to help a friend out off the clock in an attempt to save them money and that back fired. These are not OEM LiftMaster sensors even though they advertise the full part number in the discussion (deceptive sales tactics). The hardware that came with the sensors were not threaded so they couldn’t be used. Luckily I had extras from work. After splicing the wires black to black and white to white none of the sensors worked on either of the 2 doors. I then revered the splices to make sure a polarity mistake didn’t happen from the factory, this also didn’t work. I then plugged the sensors directly into both motor terminals to rule out logic board and the wiring to the opener being a possible issue. Nothing worked. So we went to Home Depot and bought the Chamberlain sensors and they worked on first install, came with useable hardware, and were legit OEM as advertised. If only one set didn’t work I’d say it’s a fluke but both is just a bad product and waste of time attempting multiple ways to make them work. This job should have been 15-20 min but took almost 2 hours with the Home Depot trip factored in. Hopefully this review saves you from wasting your time.

My daugher installed them, she had to look at other videos. The link provided was for remote controls, so not applicable. She used regular wire nuts, the ones provided " the new version", even after she pressed to lock the wire in, the wire would still come out, so just make sure you have your own nuts, no pun intended

They work and they're cheap. Unfortunately for me the LED faces the wrong way when mounted on my existing brackets, so they were of no help. Also, when hooking black to black and white to white wire, they did not work. I had to swap the poliarity and then they worked fine. The opener is a post 1997 liftmaster, who also made many of the craftsman units as well.

These sensors were an exact match for my Liftmaster garage door opener. Make sure to check the wiring configuration! I ran into the same problem as other raters. The wiring is reversed; the blacked stripe wire and solid white wire were the reverse of my original sensor wires. I just reversed them and everything worked as expected. These new sensors even worked with the sun shining into them at an angle, which my older ones stopped doing as they aged.

How can I say, this product worked as intended, however like others have observed the wire color (hotwire) is wrong. I have already cut the wire and installed the sensors, thus cannot return. It took me a while to figure it out. Originally I thought my opener is bad. Wasted some energy and time, but got the problem solved. Would have been 4 to 5 stars.

A garage sensor malfunction can be an anxiety-inducing experience. Do I need a new opener? Did the entire device fail? Did Alexa destroy it? A lot of times, it could be that the two sensors near the garage door base have failed. This will do the trick. You don't need to replace the entire wiring to do this. TIPS - Make sure you cut the power first...you can do this by removing the sensor wires from the garage door opener housing (no need to power down the house). Unscrew the sensors from the brackets. Before you start cutting, make sure you measure how much line you need to connect the new sensor to the old wire. Always leave way more than you need, since you can always bind the wires with a zip line. Now, using wire strippers, you will need to remove about one inch of the coating on both sets of wires (the new sensor and the old wiring). Here is where it's tricky - one part of the wire is white, and one is striped. if you match them up, they should work, but I know some people had to flip them. Once the wires are connected, you can then go ahead and plug the wires back into the opener housing. What I found was only one of the sensors lit up, and I could never get the other one to stay lit. DUH!!!!! You will need to line them up for them both to get full power. Once they both light up, reattach the, to the bracket, and you should be good to go. Works perfectly...

Muy bueno. Eso soluciono mi problema y no tuve que gastar en un tecnico. Yo solito los puse y soy bien burro para lo electrico. 1 año despues y siguen funcionando.

منتاز جدا وحل مشكلة ان الباب وقت الاقفال يرفض النزول لازم اضغط الزر بيدي لين يوصل تحت

Easy to install. Works well with the wires from the old sensor

Conforme à la description.

Looks like they are easy to Install
