  1. Worked great for Liftmaster 1994 model 5 Star Review

    Posted by on Nov 23rd 2021

    I really liked that they connected to the garage door rails and not the wall. Installed two in under 10 minutes and both worked great!

  2. 41A4373A Replacement Kit Works 5 Star Review

    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.

  3. Worked great for me!!! 4 Star Review

    Posted by on Feb 4th 2021

    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.

    February 2021.

    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.

  4. Easy to install and they work. 5 Star Review

    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.

  5. 41A4373A Replacement Sensors 5 Star Review

    Posted by on Oct 1st 2020

    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.

    Easy to install, fit in old brackets, works great, timely delivery, good price

  7. Sensor Change 4 Star Review

    Posted by on Dec 17th 2019

    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.

  8. Easy to hook up and set 5 Star Review

    Easy to install, I had old units that stopped working and needed to replace. Very good price and fast delivery. Thank You

  9. It does work!!! 5 Star Review

    Posted by on Jan 9th 2018

    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.

  10. Easy and quick install... 5 Star Review

    Posted by on Dec 18th 2017

    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...
