My garage door sensors, after several years, have failed to work properly. I asked for a repair quote and was told it would cost more than $80 to repair and that was if they ran into no complications. I decided the proposed charges were excessive and chose to change out the sensors myself.

To install, cut the wires from the old sensors and remove from their mount. Save the mounting bolts as none are included with the safety beam sensor kit. Splice the wires and connect to the new sensors using the supplied crimp connectors. Align the sensors using the alignment indicator lights. Then throw away the old sensors.

For me purchasing this lit and spending about 15 minutes in the garage is well worth the savings. If you are a do-it-yourselfer, perhaps this kit is for you too.


PRO:
Simple to install
They work like the originals

CON:
Mounting bolts not included

My receiving eye LED light was very dim and would go completely off when it got really cold down here in S. Florida, Broward Co. 12/27/10 (36 degrees!)

So what would happen is when I would go to press the wall button to have the garage door go down, it would go down for like 7" then automatically go back up on it's own - and the light would blink 10 times.

So I bought the two replacements, (comes in a kit, with both) that were exact to the original model numbers...

1) I only replaced the receiving eye and the LED light wasn't as bright as the sending eye - and I still had the same problem.

2) I then replaced the sending eye and adjusted them so they can "see" each other, Everything Works Perfect NOW!!!

For me at least - adjusting them was a little tricky, because they are very touchy and must be aligned perfectly.
Just make sure the receiving eye LED light is not fluttering or blinking really fast, because it won't work.

Even in the cold weather, the LED lights are bright and the door goes down and the safety beam works when it is blocked and the door goes up automatically the way it should.

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.

Good instructions, easy to install, works fine. Splicing the wires was the hardest part of the job. Cheapest price on the internet.

These Liftmaster 41A4373A Garage Door Opener Safety Beams were needed to replace the broken safety beams that came with the Sears Craftsman Garage Door opener I purchased & installed over 10 years ago. The new beams were an exact replacement product for the original beams and replacement/installation was very easy. These new beams work great.

Replacing old sensors that did not work when the temps get below 40. Very easy to install, and they seem to work very well.

After struggling with my sensors for years, which would just about align as long as touched them, bent the wires just right, etc, my sensors finally failed. Rather than install a new system, I decided I'd just replace the sensors, though with some dread as I anticipated many more years of the same. My originals were from about 1996; these are excellent. Crimp and splice connectors are included to make installation a breeze. And the new sensors are far more easily aligned, and not impressed by fleeting breaks in the beam (such as a cat running out).

Only downside, though: keep your original mounting bolts from your old set. None are included with this. All in all, I couldn't be happier.

Had to splice a wire to get the connection to work. The connectors supplied didn't fit correctly. However, after that it works great, and I haven't had a problem since. I thought they were a little overpriced, but you are kind of stuck, as you need them to get the garage to work.

Product seems to fit the bill but absolutely no instructions given on proper installation technique. Small plastic buttons for slicing wires not clearly shown how to use or install.

Perfect replacement for my damaged safety beams. The instructions were understandable, and installation took less than 15 minutes. Compatible with my 18 year-old Sears garage door opener.
