First, let me start by mentioning that if you have a Chamberlain Liftmaster Garage Door Opener and are having issues with your remote control, you may want to check if you installed LED lamps. If so, use Halogen or incandescent lightbulbs (if you can find any). On mine, I had to wait until the light went out before I could open/close the garage door, and it drove me crazy for a few years. Replacing the lamps with Halogens fixed the problem.I began having other issues where the door would easily reverse, and at first, I thought it was because the garage door was so old and maybe the rollers or the track was worn. I disconnected the garage door, and the same thing happened. I also saw an LED blinking on the opener. I checked the owner's manual, and the number of blinks indicated a problem with the sensors. I replaced the sensors with these, and it's like new again. In fact, these are better than the original sensors because the LED lamps on them are much brighter, and the brackets to hold the sensors are superb. One other thing to note is if you measure the voltage to the sensors it will be about six volts. The black stripe on the sensors goes to the positive side.Would highly recommend purchasing.
