Chamberlain B4603T MYQ Smart Garage Door Opener, Ultra Quiet Belt Drive, 3/4-HP Motor - Quantity 1

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!

Quiet and easy install with the BILT app

Replaced a 17 year old Craftsman unit. The BILT app has 3D video showing each step including safety instructions. Since I had a Craftsman, the wall and ceiling brackets all lined up making replacement a breeze. The powerful 3/4 HP motor and belt drive replaced a chain and 1/2 HP. The sound is so much quieter and the unit slows down as it reaches the floor- unlike the old unit which slammed at times. Tip- watch the video a few steps ahead and use rotating features on app to see if left for your assembly is left on your parts. If you mess up plugged in metal bars, you can bend all the tabs that locked a fitting together to pull out a bar. Definitely helps to have two people raise the unit into place. Instructions say you can place unit on a ladder, but a person is better. I used bungee cords to help suspend the unit from ceiling just in case it slipped. Great unit. My Q install was quick so you can monitor doors from cell phone. Ever wonder if you closed a door? This eliminates the stress.

Best opener ever easy installation and easy programming

Other than my having gone through the trouble of installing and removing the first opener, which was defective, the replacement works very well. Once the seller realized I had a defective opener, after phone troubleshooting with Chamberlain, they quickly sent a prepaid return shipping label for the bad one.The replacement opener works fabulously and is relatively quiet. However, I did have to purchase the installation extension kit since my garage door is 8’ tall.The motion sensor built into the wall switch is a nice plus and keeps the lights from turning off on you prematurely.The “MyQ” App is super easy to use and gives you full functionality with your smartphone (I use an iPhone so not sure on Androids).Installation using the “BILT” App video tutorial was fairly easy and straight forward. Even though I was able to install the opener by myself I would recommend having a helper.

This opener was as easy to install as the one it replaced, but is mutch quieter. Only issue was no instruction manual, however Chamberlain has a website video with complete step by step instructions, which oddly mentions referring to instruction manual they don't provide. Additional information, according to Prop 65 (July 1, 2019 Per SB-696) this garage door opener should not be sold in the state of California without the battery backup.

This unit replaced our old screw drive unit. We got the B4603T and it is MUCH quieter. We also like the ability to open/close via the app (and also just check if the door is open or closed) and the overhead light being triggered by the motion sensor built into the wall switch (there's a little door you have to open on the wall switch to access the motion sensor control).Note that the included remotes don't have as much range as the Homelink system built into our car's rearview mirror. With Homelink we can open the door from further away.If you plan to install yourself, make sure you keep your garage door level when you are manually lowering it as you are installing the head unit. Our door got off-center and it became a hassle, but that was just me being a first time installer. Having an extra person help with the install is very handy during a few of the steps.

Opener appears to be quite powerful. It handles an old heavy wood garage door. Straight forward installation using the on-line app BILT. Would be nice if they included hardware to hang the operer from the ceiling. Fortunately, I had extra hardware from previous projects that did the job.
