Typical problem as others with my old sensor...would stop working when temperatures dropped below 50 degrees. The replacement works perfectly. I was even able to use my existing brackets. Great replacement for my 1995 LiftMaster opener.

I have a Craftsman model 139.53824 1/2 HP opener made in January '93. The original sensors for my unit are 41A4373A.
I bought this kit and installed it. Although many reviews state that these replacement sensors will only work with units manufactured after 1997, these sensors worked flawlessly with my 1993 unit. The mounting brackets mounted easily on the rails. I like them much better than the originals. The little wire connectors that come with the kit are easy to use and I believe they have some sealant inside to help prevent corrosion in later years.
My only complaint is with the customer service with this company. I took the gamble on compatibility and just bought and installed the sensors. Fortunately they worked.
However, I tried multiple times to call the company to ask about compatibility. I only got to a voicemail message telling me to email the company with any questions. I did in fact email on two separate occasions. I did not receive a response from either email.
So....I am writing this review to help the next homeowner. I am not writing as a plug for the company. I believe if they refuse to answer calls then they should respond in the manner in which they say they will. If they had responded I'd give 5 stars.
So...5 stars for the equipment and ease of installation. *0* stars for customer service.

Ordered replacement sensors for our garage door. The part number was different but as stated on this site the new sensors would work with my opener. I ordered the ones with new brackets. You will need them easy to attach to the rails. The directions were easy to read and follow. Had no problem splicing the wires and lining the sensors up. Worked the first time. Took about to change both. The sending sensor is amber, the receiving sensor is green. They are not marked like my old ones.

I have a 1996 Lift Master 1245. These sensors were a great replacement for the old OEM versions that became defective over time. They seem sturdier and we’re easy to install. The brackets were helpful too. They clip to the rails and I put them right above the old ones, which seem as if they will help with the stability of the new ones. The new brackets are more protective in that they cover the sensors as compared to the old ones where the sensors were more exposed and prone to being biffed by a broom or anything else that could make contact with it. Great value vs. the OEM ones that have been discontinued, but are still our there at an inflated price.

The sensors are working great! But it took me a bit of time to figure out how to attach them so they were clear of the rail. Since there wasn't anything in the instructions about it, it took a little more time but I finally figured it out. The door is working and that's all that matters.

This part number does not match what actually came. The ones that came are the newer version designed specifically for models 1997 or newer. However it does work for the models 1993 to 1997. The installation was about as easy as you could get. Took less then 15 minutes. They look more durable then the originals.

I ordered the 41A4373A Replacement Kit... Removed the old sensors and mounting brackets and installed the new ones... Lining up the sensors was quick and simple... Garage door opener was back in service in no time... Thanks, I had my doubts about the brackets at first, but once installed they were solid and well attached...

I ordered the 41A4373A Replacement Kit LIFTMASTER GARAGE DOOR SAFETY BEAMS Sears Craftsman for my door because you can't find the original part any more. It worked like a charm. The hardest part was stripping the insulation off of 18yr old existing wires. It works as it should I tested it to make sure it goes back up if they is something in the way. I have not had any cold weather since I installed it. The old one would work in warm weather but not cold.
