CHAMBERLAINC2405 MYQ Smart Garage Door Opener, Chain Drive, 1/2-HP Motor, Dual Light - Quantity 1

I replaced a 15 year old 1/2 hp Chamberlain LiftMaster chain drive motor unit, with this one. I purchased the unit from Amazon, and had a local garage door company install for a nominal fee. (I didn't feel comfortable replacing the motor unit myself)So, I can't speak to the ease of installation, or replacement installation... other than to say, it only took 30 minutes for the local garage door company's technician to replace the new Chamberlain motor unit + interior wall mounted controller + exterior keypad, & also programmed the new car remotes/controllers. All in 30 minutes.As part of that installation, the local technician used my existing single one-piece rail & full chain system, that was already in place from my older unit. He just replaced the motor unit as part of the assembly.Which brings me to my 2 star rating for "sturdiness" -- Before replacing only the motor unit, he explained to me that this newer unit... while it *does* come with a rail and a chain system in the box... the new unit rail is not a single, one-piece rail (obviously, based on the box size)... it's a rail system comprised of 5 attaching parts. Which could be more prone to failure, than a single one-piece rail system.Additionally, the chain that came with this new unit is a 80/20 chain system. It's about 80% of actual chain, and the other 20% is tied together with a steel thread. Which obviously is not as strong/resilient as a full chain system.The technician literally told me: "Your existing single piece rail & single piece chain will have a longer life than this new motor unit you just bought."For that reason... for "sturdiness" of the overall product, I ranked 2 stars.As for the motor unit itself... I am very pleased with it.- Installation was a breeze, if you're replacing an existing 1/2 hp Chamberlain LiftMaster motor unit.- It is MUCH more quiet than the previous generation of Chamberlain LiftMaster motor units.- This model has two lights, as opposed to a single light in my previous Chamberlain unit. It makes a world of difference.- The myQ app that works with your home's wifi is for the most part, very good. You can control open/close of the garage door from anywhere, and you can setup alerts on your smartphone to notify you anytime the garage door is opened/closed. You can even add "guests" to the myQ mobile app, so they can open/close your garage door... say, if you're out of town & they're taking care of your house/pets/etcThat said about the myQ wifi app, some "drawbacks" that I've noticed about the myQ wifi app:1. The myQ app does not have a function to turn on the motor unit's lights, nor engage the "lock" function of the motor unit... from the app (as you would using the interior wall mounted controller)2. The myQ app is VERY persistent about suggesting you to setup your wifi controlled garage door opener, to allow for Amazon deliveries. In the initial setup to connect the unit to your wifi, the phone app will say "setup complete" and then take you a screen that prompts to allow for Amazon deliveries, for Prime members. You have to close out of the app setup to decline allowing Amazon delivery access, without knowing whether it really is completed (it is).Some other notes:- This newer unit uses a different frequency than the older generation(s) of Chamberlain LiftMaster units. Expect to need: new car remotes, new interior wall mounted controller, new exterior keypad. Although our Chamberlain universal car remotes we bought 5 years ago from a local hardware store, they could still be programmed to control this new unit.- While the pictures of the interior wall mounted controller doesn't show it, the interior wall mounted controller DOES include a "lock" function (hidden under the fold-up open/close button), as well as a "light" functionAll in all, I am very pleased with this new Chamberlain LiftMaster unit.

It was easy to install but the digital instructions do suck a bit. Once all the bar pieces are in the proper configuration it went up fast. I didn’t bother with the app for opening the door but the preprogrammed fobs worked and I paired to my spouses universal cars opener no problem. I would buy again.

Unit arrived well boxed with no damage. Purchased to replace 24 yr old Raynor navigator. (Also made by Liftmaster) Previous unit was chain drive with one piece rail system. I decided to try and replace just the head and use the existing Rail and chain along with the existing electronic eyes and wiring. replacement took about 30 minutes and another 30 minutes to link up controllers, keypad, andMyQ. All items functioned normally!! I saved all items in case of any failures, but I don't anticipate any. IT is chain drive which is louder but it is still quieter than old motor, and there was no headaches on setting up new rail chain system.

The opener is great, although it was missing the following parts out of the box. 1) 041A6689 is a D-shaped threaded shaft. 2) Missing 2 of the 'master-links' for the chain. Luckily I was able to salvage all of these parts off of my 23-year-old Craftsman model that I was replacing and they were a direct fit. I also was able to use my existing wiring from my 23-year old setup, as it also utilized a red/white for the panel and a pair of black/white wires for the optical sensors. It also bolted right up and fit in the same mounting bracket as my 23-year-old model from 1992. All-in-all not a bad deal. I was able to obtain open-box for 147, which was significantly off full price!One thing I will mention is that you need to set the upper and lower travel-limits once via a combination of buttons on the back of the unit where the wires go. Once the upper and lower travel-limits are set then it works flawlessly.

Replaced old device. Very nice.

Nice garage door opener easy to put up and it runs quietly.

Works great. Installation instructions online are interesting: excellent description and graphics. The DIY skill level requirement is moderate. Expect to have to purchase additional angle brackets and supports if you have anything unusual in the mounting situation. I purchased additional installation materials to fit beams and joists, and I did need them.

This was very easy to install. Directions are very clear once you scan the bar code and it’s step by step in your phone. Comes with plenty of wire for the sensors. You can link the garage door to your phone to open and close it from anywhere. It operates very quietly.
