CHAMBERLAING801CB-P LiftMaster/Craftsman 801CB Garage Door Opener Replacement Safety, Includes 2 Sensors, Mounting Brackets and Hardware, 1 Pack, One Color

Works great! Going through my amazon history and thought these should rate a review...Replaced my old garage door sensors about 5 years ago with these and they've worked great ever since! Easy to install, direct replacement. Solid purchase. Good price!

I had new garage doors installed about 3-4 years ago and they functioned perfectly (including the safety sensors) from day one. Unfortunately, we recently starting having problems with the garage doors closing in the later afternoon (North facing driveway). It was pretty clear that the sun was shining directly into the safety sensors which caused the lift motor to reverse. This was a major problem as I have a few kids who are great on their iPhones but not so great when it comes to more "complicated" home problems (i.e. running a dishwasher, washing machine, lawn mower, and garage doors). It is really frustrating to be at work and have a kid call to say they can't get the garage doors to close. It is even more frustrating to try to explain how to solve the problem to the helpless teenagers.....Enough said. Time to solve the problem.I did lots of internet research and found all kinds of hokey solutions (i.e. toilet paper roll, black plastic sun shades, etc...) but none of those seemed reliable enough to protect me from the dreaded call from the teenagers so I looked into the problem further and it appears that long-term exposure to sunlight can cause the older generation of photoelectric safety sensors to deteriorate. I decided to replace the old sensors with these hoping it would solve the problem. Good news! They did!I do have a couple of tips that might help with the install if you choose to replace your old sensors with these. First, I used a black permanent marker to mark the top location of the brackets for the old sensors. I then removed the old brackets and installed the new brackets with the new sensors as a complete assembly with the top of the new bracket at the marked line. That is much easier than installing the new bracket and then installing the new sensor (you do need to use the new bracket as the sensors are shaped differently).Next, I pre-wound some of the excess wire around a pen to create a little buffer in case I needed to move the new sensor up or down. It is only possible to do this easily if you do it before the wires from the sensor are connected to the wires from the garage door motor. I now had a buffer that would allow vertical movement if my marks were off.Finally, I cut the old sensor out one wire at a time so that I did not have to unplug the garage door motor itself. If you cut one wire at a time, you cannot create a short which might damage the garage door motor and unplugging the motor itself is an unnecessary extra step. The connectors that are included with the new sensors were perfect and easily secured with a simple pliers so all good!Once the install and electrical connections were complete, it was easy to verify the sensors were properly aligned. One sensor has an amber light and the other has a green light. It does not appear to matter how you install them. Both lights are constantly on when things are properly aligned and they flash if there is a problem so easy to verify the install. Mine turned out to be correct so I went on to test the up/down performance at the same time of day when we usually have trouble. Everything worked perfectly and I no longer have problems with the sunlight causing the garage doors to reverse!These turned out to be a simple solution to a frustrating problem. I highly recommend the kit if you are having similar problems with your garage doors auto reversing due to sunlight!

My previous sensors failed and needed a replacement. Super simple to install and worked flawlessly. No reprogramming. I love that they have indicator lights showing when there is a connection between the two sensors. Made aligning them 5-second job.

Moved into a new home and the previous owner told me the garage door would stick when it was cold and I had to hold down the garage close button.. once I moved in I quickly realized the sensors were no good. He had the old style sensors, so I got these and had them spliced in and mounted in about 10 minutes. Unfortunately I had to modify the brackets a bit to mount (bc of how the old ones were mounted). A few quick bends with a pair of pliers and these were up and running. First open and close were successful and a second test with a box in the way triggered the safety reverse, as they’re supposed to. Excellent product. I connected these to a chamberlain garage door opener.

Installing the sensors was pretty straightforward with a couple caveats. One is that there are no instructions in the box so you have to just kind of figure it out but if you're doing a replacement you can look at how the existing sensors are mounted as a guide. Not very hard if you're at all handy and have a pair of electricians pliers.The other big item (and the reason I'm taking a star away) is that the included wire splices are garbage. I've never spliced low voltage wire before so had to look up how to use this style of splice but after installing them and getting no results I spent 20-30 minutes trying to troubleshoot until I realized the splices are just very finicky. Once I got it sorted they work great.If they included a few wago style splices in the box this would be an easy 5 stars.

I’ve owned my home for 12 years. For the first 6 or so, the garage door opener worked just fine. Then, it started not closing when the sun was really bright, then when the sun was out at all, and finally, it stopped working altogether.I tried all the things — readjusting the sensors, cleaning the lenses, even toilet paper rolls on the sensors to block glare. Nothing worked.What followed was several years of having to have someone inside the house hold down the garage door button it would over-ride the sensors. We essentially didn’t have a garage door opener.Finally, after procrastinating for probably 3 years, I bought this set of replacement sensors. I had a little bit of experience with wiring as I’d worked my basement when I finished it a couple years back, so I had a good set of electrical pliers, and was comfortable splicing wires.It took about 20 minutes to clip off the two old sensors (they were hard wired) and splice the new sensors using the provided connectors. I probably left too much wire, but who cares. No one is going to see it.Once everything was connected I clicked the button on one of my remotes, and for the first time in years, the garage door closed in the light of day!I cannot overstate how liberating it is to actually have a garage door opener that opens! And with how easy the repair was, I should have done this years ago!
