Make your garage work for you. Simplify your life, safeguard your family and experience the next generation in garage technology with the B4603T Chamberlain® Garage Door Opener powered by myQ®. Review: Door opens with cellphone app, the control panel, and the remote. Quiet and easy to install. - Chamberlain B4603T is much quieter than old traditional chain opener. I liked the myQ app very much. You download the app and it shows detailed animation and diagram how to install guide. I think you could install it yourself. It was compatible with my old garage door(lift master security +), so no need to replace the railing nor bracket on the ceiling of the garage. It has high quality build and strong horse power to work with 2 car garage door easy. It is wired to the house electric, so no worries for battery. You can download app on your phone, and open the garage door while you are on a vacation far away from home when desertcart delivery drop off your important items. It also came with 2 remotes which you can keep inside your cars. I got a control panel installed outside, and you can open by putting your pass cord. It works really well, and I am quite happy with this purchase. Review: Very quiet and smooth. The light disappoints somewhat. - 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! ## Features - Smartphone control: Download the myQ app and follow the steps to connect your new garage door opener so you can control, secure and monitor the garage from your smartphone - anytime, from anywhere - Integrated advanced LED lighting: Purposely brightens high traffic areas of the garage, motion activated, 1,000 lumens - Quiet operation: An ultra-quiet DC motor and soft start/stop smooth operation ensures for comfortable living spaces near the garage - Next generation garage technology: Improved Wi-Fi connectivity and enhanced memory to support new myQ features and solutions - Integrated Bluetooth technology: Reduces setup time and makes it even easier to connect to the myQ app, other myQ devices and smart home technology solutions ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09B2PRPN3 | | Batteries Required? | No | | Best Sellers Rank | #188,974 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #36 in Garage Door Openers | | Color | Blue | | Customer Reviews | 4.5 4.5 out of 5 stars (785) | | Date First Available | July 22, 2021 | | Included Components | 2 x 3-Button Remotes, 2 x 3-Button Remotes, Motion-Detecting Wall Control, Wireless keypad, Safety Sensors, Motion-Detecting Wall Control, Safety Sensors, Wireless keypad | | Item Package Quantity | 1 | | Item Weight | 32.8 pounds | | Item model number | B4603T | | Manufacturer | CHAMBERLAIN CORP | | Material | Plastic | | Mounting Type | Door Mount | | Part Number | B4603T | | Product Dimensions | 10 x 13.1 x 27.9 inches | | Size | No Size | | Style | B4603 Garage Door Opener | | Warranty Description | Accessories: 1 Years, Belt: Lifetime, Motor: Lifetime, Parts: 5 Years | ## Images ![B4603T MYQ Smart Garage Door Opener, Ultra Quiet Belt Drive, 3/4-HP Motor - Quantity 1 - Image 1](https://m.media-amazon.com/images/I/51Xn4t525yL.jpg) ![B4603T MYQ Smart Garage Door Opener, Ultra Quiet Belt Drive, 3/4-HP Motor - Quantity 1 - Image 2](https://m.media-amazon.com/images/I/51DhlVOkGbL.jpg) ![B4603T MYQ Smart Garage Door Opener, Ultra Quiet Belt Drive, 3/4-HP Motor - Quantity 1 - Image 3](https://m.media-amazon.com/images/I/61A4zRg1kgL.jpg) ![B4603T MYQ Smart Garage Door Opener, Ultra Quiet Belt Drive, 3/4-HP Motor - Quantity 1 - Image 4](https://m.media-amazon.com/images/I/51LkbvOqE0L.jpg) ![B4603T MYQ Smart Garage Door Opener, Ultra Quiet Belt Drive, 3/4-HP Motor - Quantity 1 - Image 5](https://m.media-amazon.com/images/I/51BRUis0dHL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Will this opener handle a 9' tall x 16' wide insulated door?** A: Bradley, since a standard garage door is 7' tall, you'll need a 7710CB 10-Foot Chain Drive Garage Door Opener Extension Kit. Let us know if you have any other questions. **Q: Does this work with homelink?** A: BKM79, yes, this opener works with HomeLink. Note that if your vehicle was made prior to 2012, you may need the HomeLink Compatibility Bridge. To see if you need the Bridge, please visit this site: http://bridge.chamberlain.com/#/intro **Q: do the remotes come pre programmed?** A: Iregena, yes they do come pre-programmed. Let us know if you have any other questions. **Q: Can this opener be converted to a belt drive?** A: No, the C870 cannot be converted to a belt drive. The sprockets and the motor shaft differ between belt and chain drive. Let us know if you have any other questions. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Door opens with cellphone app, the control panel, and the remote.

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. ## Frequently Bought Together - Chamberlain B4603T MYQ Smart Garage Door Opener, Ultra Quiet Belt Drive, 3/4-HP Motor - Quantity 1 - Chamberlain Group G8808CB-P Chamberlain 8808CB 8-Foot, Compatible Whisper Drive Plus Models, Includes Replacement Belt Garage Door Opener 8 Ft Rail Extension Kit - CHAMBERLAIN B2401 Smart Quiet Belt Drive Garage Door Opener, Gray --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/352103451-b4603t-myq-smart-garage-door-opener-ultra-quiet-belt-drive](https://www.desertcart.vn/products/352103451-b4603t-myq-smart-garage-door-opener-ultra-quiet-belt-drive) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
