820CB Replacement Garage Door Safety Sensor, 2-Pk. - Quantity 1

I've been having an issue for quite some time now that's been getting worse. The door would sometimes start to close, then reverse as if the safety sensor was tripped though it wasn't. Would happen at certain times of the day as well, when the sun was hitting the garage. I could never see the little green light go out or anything, so really thought it was something else but these are too inexpensive not to try. Been installed and working for about 2 weeks now and the door hasn't stopped/reversed a single time since. Installation was easy with these. Used the existing brackets and I didn't have to do anything extraordinary to get them aligned. Wire was a little tough to separate in order to strip. I had to use a knife to cut down the center to get them apart. Minor inconvenience though. The included connectors worked fine, and there was an extra just in case. I like how bright the LEDs are on these, there's no issue telling if the senor is being tripped or not. Very bright and large.

Los sensores anteriores ya no funcionaban correctamente, decidí cambiarlos por estos, tengo motor chamberlain y funcionaron excelente, muy fácil la instalación sin necesidad de contratar técnico.

Works with my Liftmaster garage door opener. The included wire clips were helpful for attaching new sensors’ wires to the original wires from the old sensors. The LED indicators on each sensor are bright and easy to see.

I was having intermittent issues with my Jackshaft Liftmaster garage door opener not being able to close. When I tried to close it, it would move a couple of inches, but it would reverse since the old safety sensors erroneously thought there was an obstruction. I contacted my garage door guy who installed it 13 years ago and he suggested replacing the safety sensors as a possible solution. This was the easiest, cheapest, and most cost-effective repair to try. My existing safety sensors did not give me any indication of failure like blinking lights. I would never have suspected that the safety sensors was the problem. These safety sensors are a little smaller than my old ones, but these worked just fine and are perfect replacements. I was able to use the existing mounting hardware, so installation was super easy. Just splice the matching-colored wires and adjust the sensors so they are aligned. All the parts that you need are included, even the wire connectors. They even provided an extra wire connector that I needed because I didn't crimp one of the connectors properly. It took me less than 45 minutes even with clean up, but I am sure others can do in 15 to 30 minutes. I took my time, since I didn't want to make any mistakes. If I called a professional to do the replacement, the sensor would have cost me $75 and the service call and labor would have been about $150 or so. Beware of unscrupulous garage door companies who want you to spend thousands of dollars on a garage door refresh (replacing all the hardware of the garage door like rollers, cables, spools, springs, etc.) and/or replacing the garage door opener itself that isn't needed. I am lucky to have an honest garage door installer that helped and saved me money. I asked him if I needed to replace any hardware and he said no, unless I just wanted to spend money. This is definitely an easy DIY project which saves you a lot of money for something that is so easy to do. I expect these sensors to be durable and last me over ten years like my old ones.
