Style: B4603 Garage Door Opener
I’ve installed a number of garage door openers in the past so I found the installation fairly straight forward just using the enclosed installation manual. However, the built in LED light didn’t work. In looking through the manual under ‘troubleshooting’ the instructions for addressing this were not at all detailed (see the photo). In looking at the opener it’s not at all obvious either as to what needs to be done “to remove the cover”. I reached out to Chamberlain customer support and they were very helpful. They ended up sending me a new light assembly (which encompasses most of the bottom of the unit, see photos). Included with the new light were more detailed instructions on how to remove the old light assembly. After taking out the screws and lowering the old light assemble, the wire connection came apart – clearly they weren’t connected tightly in assembly. Connecting the wires fixed the issue and I have an extra LED light if the original fails. By the way – if you need more detailed instructions on removing the light assembly do a Google search on the part number: 041-0203-000. From there, click on the chamberlain link to the part, which has a link to the instructions. As to how the opener works: I love it. It’s very quiet and works very smoothly. The MyQ app was fairly easy to setup and works well. The light though is somewhat underwhelming, at least in my specific situation, in that it shines on the back wall of the garage. My door to the house is on the side wall, more towards the front of the garage, so there’s not a lot of light that shines on it. I think having an adjustable light (one that could be pointed to where you want it) would be ideal. In the end, I’ll give this 4 stars: Great mechanicals, very smooth and quiet but the light is a bit of a disappointment. Edit: I was able to rotate the light 180 degrees and have it point to the garage door, thus better light the entrance to my house. See the last picture. Much improved, will up to 5 stars. Chamberlain should outline the steps for this in their manual!

My previous garage door opener had a recurring issue with the chain jamming so I replaced it with this one. It's very quiet and works well. MYQ means it can work from your phone over wireless networks so you can command it to open before the house is in sight. It also means that it can be used with Amazon deliveries so packages can be left safe in the garage instead of on the porch. I was a little hesitant to allowing access to my garage but I installed with a MYQ compatible camera and MYQ door lock to alleviate my security paranoia. The camera records the garage as the door opens when the Amazon delivery driver uses a one time delivery code to command the garage open. The lock on the door to the house will self-lock when the driver sends the code to open the garage and then will unlock again after the garage has closed. I can see all this happen on my phone and have alerts sent as well. Basic MYQ functionality is free but storing videos has a subscription fee and is necessary if you want to actually catch the video in time (starting the app, selecting the display, and the video beginning to stream). There are versions of the garage door opener with a built in camera. I paid to have this installed by a local company I used before and the install price was reasonable.

NIce cosmetic view, have power and is silent, but here are the negatives, Dont works with alexa, Im having issues with the MyQ app, left outside my home after an error in the app, constantly is erasing the up and down limits, need to reprogram in order to start working again. Be prepare with a remote and a spare key to enter your home. This issues make me lose confiability in the product to work when needed and expected. Note today have to jump the fence to enter my home and open from inside, install the key number remote and program, after that have to AGAIN reprogram the limits. Take about 4 times to make it working again. Will contact chamberlain to report this issue. UPDATE, After carefully inspect the close funtion, notice the sensor blink during closing operation. Problem solve, sensor are very sensitive, a little bend in the base of the sensor was the issue, movement from the door while closing make the sensor activate and cancel the close operation. Door have been working after this adjustment.
