Used this 820CB to replace 801CB on my LiftMaster MyQ. Worked awesome! In a pinch and everything I needed came quick! Thank you logistic geniuses and MyQ designers!

Used these to replace the sensors on a discontinued Ryobi garage door opener. The OEM sensors were becoming overly sensitive to sunlight, and seemed to be having intermittent connectivity to the opener even after all wiring was confirmed solid. Have to believe after 10 years the transmitter sensor was weak. These seem to be compatible and reliable.

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 garage door stopping closing when the outside temps got colder, so research led me to replacing the sensors. I checked the opener's manufacturing date, and it was 2005, so I then checked reviews for that version of the sensors and didn't see much difference in ratings or performance for the cheaper generic ones so that is what I first bought. Turns out that the previous homeowner replaced the opener in 2005 but reused the older pre-1997 sensors! Different size and connection and everything. But when the generic ones arrived, I thought let's try 'em and see. Massive logistics issues - no way to mount the new sensor brackets at 6 inches or lower due to 8" concrete foundation, and they didn't fit in the older and larger existing brackets which were firmed drilled into said concrete foundation. I got the new ones installed in the new brackets at 10" height above floor but had the receiving sensor on the sunlight side, so I switched them. They never hooked up and the light indicating power and version was so small and dim that it was a frustrating experience. Next step was to try these sensors designed for this 2005 opener. Best decision ever. These Chamberlain sensors (our opener is a Liftmaster) are smaller than the generic ones but were much easier to install on the newer brackets that came with them, and much easier to align. Having 24" of wiring instead of 16" helped in that regard. But the two keys for me were the fact that the receiving sensor (green light) was clearly labeled, and once installed those larger brighter colored lights were a Godsend in a dark garage. These are well worth the extra money compared to the cheaper generic ones, and if you are a DIY type who gets easily frustrated then you definitely need these.

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.

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.

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!
