2 bulbs no LED.

Asked by tony May 6, 2021

There could be an issue with the garage door balance/tension We would recommend to contact a local dealer/tech in your area to troubleshoot or Chamberlain support for further assistance.

Does this unit have a motion sensing light or does light only come on when in use?

Asked by Doylegeo March 29, 2021

The motion sensor on door control will trigger the light bulbs to turn on when the door is activated or the safety sensor beam is broken.

That push button switch has a lot of electronic components inside, it is not just 2 metal contacts. The addition of another one might not be easy.

Asked by igoinsane67 January 20, 2021

A few thoughts. Hopefully your chain is on correct. It shouldn't be droopy or too tight, and, it should be even on both sides. I had a problem at first with setting the spring nut too tight. I suppose you followed the travel limits correctly: press middle button, then press and hold down button and release where you want it, then middle button, the press and hold the up button and release where you want it. Then middle again. Then down and up buttons to test. If you have no obstructions, the only thing that comes to mind is that you have a loose wire at eye sensor or up in the motor connections.

Asked by NotMuchRoom December 31, 2020

A few inches. You just need room to allow for movement of the chain and its pully. Also, to keep the track horizontal, you may need 2-4 inches so the top of the motor box will fit. Plus you want to be able to open the lighted side panels when programming and changing bulbs, although you can pop the sides off and not lift them straight up.

does it come with a remote there was not one in the box?

Asked by teb December 18, 2020

Yes it comes with one remote!you can work it with your phone also! I like using the phone app!

I have had this opener for about a month and we are very happy with it. It was very easy to install (we replaced a 15-year old Chamberlain unit). The belt drive is very smooth operating and very quiet compared to the chain drive unit we replaced. The only con I can think of is none of our existing Chamberlain controls and sensors worked with the new opener and had to be replaced with the new ones that came with the new opener. I guess that's to be expected after 15 years of product development.

Only buy if you want the bare minimum in accessories.
I went to my local HD to get a new GDO for my double door with future plans to add an opener on my single door. I did my research beforehand and decided to get the 3/4hp Chamberlain. However, when I got there they did not have any in-stock even though their website said there were. I quickly decided to get the 1/2 hp instead of going up in power while assuming the accessories would be the same. When I installed it I realized it did not come with a 2nd remote (at least $25) or an led bulb ($8 for GDO low interference). It also only holds one light bulb and doesn't include an exterior keypad. The wifi worked well once set up, but I got annoyed having to open the phone app to open up the door each time after I gave my wife the actual opener. I then ordered the genie 1.25 hp with back up battery, two remotes, exterior keypad, and two included LED lights for only $20 more. I moved the chamberlain to the single door and installed the genie on the double door. The genie is quieter and smoother, but the Chamberlain was a bit faster and beefier despite the lower HP rating. If I were to only buy one just based on the initial impression I would pick the genie hands down for the included value. If you want the Chamberlain brand I would recommend paying a little more to get one of their other units.

Stylish product with great features
[This review was collected as part of a promotion.] Love the style of this garage door opener, it comes with a built in WiFi which is a great feature, I can now control my garage door from anywhere in the world and get notified when someone else opens my garage door!!! It was very easy to install (highly recommend getting a second pair of hands to help) with a clear instructions manual and all the essential required hardware already included in the package. Operation is very smooth and super quite, I had it installed on a two car garage door and it's working like a charm, I wish it would have come with a little more sophisticated wall button though (such as having an LCD, motion sensor, thermometer...etc). Overall great product, great features, easy to install, works and looks great in my garage and very happy with it, highly recommended!!!

Nice Features!
[This review was collected as part of a promotion.] This is a fairly quiet belt-drive opener rated at 1/2 HP. Installation was mostly straight forward. I think it took me a few hours to install. I had zero issues aligning the safety sensors. The opener operates very smoothly. There are quieter openers on the market, but you'll probably pay more. This opener has a handfull of nice features, my favorite is the myQ funtionality which gives you the ability to connect to your home WIFI network and control this opener from anywhere in the world where you have cell service. I absolutely love that feature and the ability to set up text alerts notifying me when the door opens and closes. There are other helpful myQ add-ons that are helpful, like an indoor garage door monitor that will alert you when your door is open with an audible tone that beeps until the door is closed. You also have the ability to close the door from the monitor. The push button door control is compact with a lighted button and a small switch that allows you to turn on the light on the opener. You also get a 3-button remote control for your vehicle and there are a few compatible keychain remotes that I prefer for safety reasons. The one thing missing is the wireless keypad to enter your garage. Not a deal-breaker, but include that and quiet this opener a few more decibles and I'd give it 5 stars.

It is quiet enough when I am in the room with it but the motor sounds much louder coming up through the floor than my previous chain drive. I don’t believe the 3/4 HP equivalent I bought for my other garage would be this loud. I should have researched more and bought a better model Chamberlain.

Works well, only it's not quiet
I had an old model garage opener that was chain driven. That old unit was quieter than this brand new belt driving. Why do they say the belt is quiet? The motor on this thing is pretty loud. Other than that, works well, has basic features but plenty of add ons if you want them. Extra are all compatible.

NOT compatible with any remotes you may have, nor your car's HomeLInk remote, nor any wall switch you may have.
This garage door opener is NOT compatible with any remotes you may have, nor your car's HomeLInk remote, nor any wall switch you may have (I liked mine and wanted to keep it). In addition, this opener is noisier than my 18 yr. old opener. What's there to like?
