41A4373 Liftmaster Safety Sensors

Very easy to swap out with the old ones, worked from the get-go, couldn't have been simpler.

I had searched locally for replacement for my failed unit in town at Home Depot and Lowes, and all they carried were GENIE products. I was mistakingly told I could use the GENIE UNIVERSAL product at Home Depot, but this is incorrect...glad I found this, as it was a direct replacement of the unit I had, set up took all of 10 minutes, and works great now (in fact, it is probably better than the one I replaced, since that one had a very cheap 'connector' for the wire to attach to the units, that would occasionally vibrate loose. This unit has direct wiring into them...Much better !

Purchased these sensors and easily fixed the door. You will have to use the supplied wire splicers to replace your old sensors but it's not difficult.

Product works like a charm. I bought a generic one from Home Depot - that advertises it works with everything - but unfortunately, learnt that wasnt true. This was so easy to setup; it took me less than 5 mints.

If you are having problems with your Liftmaster/Chamberlain Garage door opener closing your door during the day, especially after noon, get these beams. Easy to replace-all needed parts enclosed including wire connectors. The price is right, these are OEM parts, and they fixed the problem.
