Pretty easy to install or replace also. Note that Chamberlain made some of the Sears Craftsman units in the past I believe. ### ⭐⭐⭐⭐⭐ Review *by J***T on 9 June 2023* The replacement part look like the original. Then, it was easy to install and it work well. ### ⭐⭐⭐⭐⭐ Review *by R***I on 6 June 2016* This is a perfect replacement of the one that I used to have. Now I do not have the problem of the door not opening when it is cold or doing a lot of programming that I used to do with the old one. For the price, which is $20 less when I buy it locally, I would recommend this product. Make sure though that when you buy this product that it matches the year of the opener. Mine is 1993 and it works fine. ## Frequently Bought Together - Chamberlain Liftmaster 41A4373A Safety Sensors - Chamberlain LiftMaster 41A6569 Metal Wall Mount Garage Door Sensor Bracket, Silver, 1 Count --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/292417736-chamberlain-41a4373a-safety-sensors](https://www.desertcart.com.cy/products/292417736-chamberlain-41a4373a-safety-sensors) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
