Review: Garage Door Works again... mine is an old Sears Craftsman unit. - These are great for replacements on my system... make sure they look like your old ones and you won't be disappointed. Pretty easy to install or replace also. Note that Chamberlain made some of the Sears Craftsman units in the past I believe.
Review: Exact Replacement for Older 1/2 HP Liftmaster (08/1995 - This was an exact replacement for an older 1/2 HP Liftmaster dated Aug,1995 (08/95). Called the local garage repair & the tech tried to convince me to buy a new opener @ $650 which quickly dropped to $500. I sized him up, said "no thanks" and blocked his number on my phone. I found this replacement sensor pair & decided to give it a try @ $50.00 I tried to get away with just replacing the receiving unit but it just erratically blinked (no steady light). When I replaced the paired sending unit & plugged in the opener, it worked just like it was new. It was a little frustrating connecting the wires to the new units but it probably had more to do with the cold weather. I will tidy up the wiring & clean up when it warms up but I have a functioning garage door opener with about 45 minutes of labor.

### ⭐⭐⭐⭐⭐ Easy replacement for older Liftmaster sensors
*by F***. on January 20, 2025*

I had to buy 2 sets of these sensors to replace ones that were manufactured in December 1996 and which began to operate very sporadically, especially when the temperature dropped below freezing. The behavior was that, sporadically, the green light on the receiving sensor would turn off, and then when I tried to close the door, the door would move for just a few inches and then bounce back up and the garage opener light would flash 10 times, which indicates a sensor issue. The failed sensors, identical to this product I purchased, worked flawlessly for about 28 years, which I suppose is reasonable, so I don't mind buying the same product again. Unfortunately, no matter where you buy these nowadays, they will be much more expensive than replacement sensors for more modern garage openers, perhaps because this model of sensor is so old that there are not many companies (maybe only Liftmaster itself?) producing them anymore, and therefore, minimal price competition. Still, these replacement sensors are cheaper than a whole new garage door opener unit which includes new sensors. So if your garage door opener motor is still working fine, but your sensors are not, then it could be worth the investment to just replace the sensors.
