    My garage door would not close unless I held down the hard-wired switch, overriding the safety sensors. I did some looking and found that the LED’s on my sensors were supposed to light up (one should stay illuminated, and the other should illuminate when the sensors are lined up). The LED’s on my old sensors were so dim, I could only see them light up if the garage was completely dark. I took a guess that I needed new sensors. Well, long story short, I ordered these and had them in a few days. Install was a breeze, it only took about 10 minutes, and all I used was a $1 pair of wire cutters. Just remove your old sensors from their mount and cut the wires, splice the new sensor’s wires with your existing garage door opener’s wires using the included crimp connectors, and mount the sensors on the included brackets (or on your existing brackets). Everything worked like a charm, and I got to impress my wife with my handyman skills!

    Make sure you check the wiring on the main unit, before you purchase. A bad connection can also prevent sensors from performing. Because my sensors were also dim, I ordered this pair. Upon receiving them, I thought I would then check the wiring on the main unit–stupid me, I know. A wire was loose, and I tightened, and the old one worked. Oh, well. I also discovered that these units did not adapt to my old mounts, and I would have to build up the wall to accomodate the shorter brackets provided. So….just a warning to avoid my errors and check all connections first, and measure your brackets. That being said, it still would have been a pretty easy fix with these new units. Now I have back up sensors! Yay!

    Installed these with no problems, works just fine. Didn’t take long to install at all and were at a good price.
