Rated 4.6 out of 5 by 33 reviewers.
Rated 5.0 out of 5.0 by Worked Great Easy install. The package refers to the receiver and transmitter, but doesn't say which is which. The green led seems to be the receiver. My garage door wouldn't go down during the day no matter how I aligned or cleaned the sensors. This set fixed the problem, Make sure to put the receiver (green) on the shady side if you've got one. I also got a can of garage door lube and sprayed it on every bearing. It's amazing how much quieter and smoother the door opens. Also installed LED bulbs in the opener housing while I was there. I hadn't known there were two bulbs (both front bulbs were out) so it is brighter now too. April 11, 2015
Rated 5.0 out of 5.0 by My 5 year headache is gone The door would only open with one push, but in order to close it we had to hold down the wall button every time. Made for a headache when we were leaving the house. I thought I would have to replace the entire system and then I saw this online. Brought it home replaced the mount and the green (receiver) sensor in about 15 minutes and it worked. I only wish that I found this product years ago. Simple to install and my door closes with one touch of the button. June 7, 2015
Rated 5.0 out of 5.0 by 15 minutes! Super easy fix-great price! You can do it, Ladies-I did! Saved over $150 in labor costs I am a bit of a Ms. fix-It. Not afraid to dive in and gives things a try, but those skills weren't even necessary! After our insane winter in Boston, I think our sensors (floor mounted) got bumped with the snowblower/shovels/extra water. The green sensor light was out completely and I read online (thanks bloggers!) that you need to replace both sensors in this case. The only way to automatically close the door was by standing and holding The wall button down. Time consuming when running late! I was a bit reluctant at first to DIY, so I got some quotes from local garage repair guys and they all wanted upwards of $200 to replace them-yikes! For less than $40, I took a gamble and bought this kit. My opener is a Whisper Plus Drive by Chamberlain manufactured in 2005. After assembling them (super easy), I mounted the sensors to the track (instead of the floor) by simply clipping them on and eyeballing the 4-6" using the bottom hole on the track on either side. I used the wire cutters to split and strip the wires (unplugged the system first, of course) and loaded them into the little button things. It said to use pliers, but I didn't have any handy so I just pressed them down with my thumbs. Plugged the system back in, crossed my fingers and voila-working like a charm now. I did not even have to adjust the brackets or level the eyes. Hubby will be so impressed. :-) as an add-on, I also bought some Pro Lube for $6 and it really helped with the loudness of the opening/closing. Finally, if you have the same model as me and your light is not working-all you have to do is pull down the white cover and unscrew the old bulbs and replace them with new ones. I used 60 watt which I think it recommends on the label. Now I have the automatic light come on and don't have to manually close the door any more. Driving into the garage will be like heaven once again. Thanks, Chamberlain and everyone who shared their fixes here and on the inter web. Good luck! June 12, 2015
Rated 1.0 out of 5.0 by Check the manufacture date on your GDO! Be careful when ordering these replacement sensors, as the package labeling mentions that they are only applicable under the following conditions: 1) GDO must have been manufactured after 1997 2) The PROGRAM button on the GDO should be Purple, Orange, or Red in color with a Yellow indicator light 3) Original sensors should have one green and one yellow light Since the Home Depot's product description on the web for these parts is limited, check your original GDO to be sure your are getting the correct replacement parts.

Rated 4.0 out of 5.0 by Got the job done The old sensors on my Sears garage door opener were faulty. These worked. Only drawback was the poorly designed connectors. Replaced them with my own then they worked fine. July 23, 2015
Rated 5.0 out of 5.0 by EZ Install I have a Chamberlain garage door unit and this was a simple replacement required because some wildlife chewed through the insulation close to the sensor and I couldn't splice it. Just match the colors of the wires and it works. Was even able to use the existing mounting brackets. While this is certainly cheaper than calling a repairman, at a cost of almost $40, it seems a little pricy - but you've got to have them for the door to work! July 7, 2015
Rated 4.0 out of 5.0 by Works like they're supposed to The only problem was that I had to modify the brackets to fit my particular installation. But I could, and I did, so they now work perfectly. July 7, 2015
Rated 5.0 out of 5.0 by Sensors PERFECT and Cheaper than a whole new Gargage Door Opener Thought we needed entirely new garage door opener. Were having to hold down wall button until door was completely open/closed AND wireless opener mounted outside would only open the door, but not close it. Friend suggested spending right at $40 for new sensors first before replacing entire garage door opener system; said that could be problem even though the sensor lights were on like they were supposed to be. It worked! That's all we needed. Everything works now the same as when new. Saved a chunk of money, too!!! September 30, 2014
