CRAFTSMAN 1/2 HP Smart Garage Door Opener – myQ Smartphone Controlled – Chain Drive, Wireless Keypad Included, Model CMXEOCG472, Red

Not much changed in 20 years.
It a good ‘ole Craftsman 1/2 HP garage door opener. I bought one about 20 years ago and it started giving me problems going down, regardless the setting it was adjusted to. This one was the same size, and the track was even the same size and design as my old one, which eliminated any compatibility issues. All the hardware was include, even though I didn’t use but half it it. The only real difference was the length of the chain and cable was about 4 inches too long on my old one to be able to reuse on the new one. All the wiring and sensors worked from my old one as well. Was very easy to install.

Watch some videos and read some of the more detailed reviews before any DY installs
Many reviewers on here have commented correctly that the instructions are unclear in some parts, and they are absolutely correct about that. I will make some comments on things I bumped into and my fixes for them below. Overall this was my first install and I had to remove some early 90’s era equipment so that slowed me down quite a bit, but I also did not (thankfully) have to replace the door, door tracks or springs.So, for starters, I advise everyone to go through the box carefully and unpack everything one piece at a time. I was not missing anything but many comments online are that parts have been missing.Next, if you are putting this together, put it together in the garage where you are mounting it and put it together unit under unit being replaced. IE – equipment lined up as it would be upon installation. I made the mistake of putting this in a mudroom to install and had it backwards, it is cumbersome to turn it around.Third, the chain tensioner is simply bizarre. The screws allegedly provided were not labelled (none of them are) nor labelled in the instructions as most others are. Also, there are two small screws in the holes where the tensioner is to be mounted, but there are many other holes around the chain sprocket that are empty. That is confusion and frankly, a stupid way to do this. At least the designers could have put the actual mounting screws in the holes (the small screws in the holes are inadequate to mount the tensioner.Next is mounting and tightening the chain. Advice – before tightening the chain, put in the master link and lock – it is impossible to put the link cover and lock hasp on when the chain has been fully tightened. Also be prepared to use 2 wrenches to do that (1/2″ I think), you will need one to hold the inner nut and the other one to tighten the outer nut. I would advise everyone to get the inner nut pretty far in as you run out of room quickly with the outer nut and if that doesnt tighten it up adequately you will have to redo it. It is much easier if you can put this on a table to do rather than on the floor, btw.If you have an existing door, some of the equipment may be salvagable but I would not recommend using any of the mounting equipment from your old opener as these things need to be precise, and bowing up the rail with a tight chain could cause the mounting bracket to warp or even worse, fall. Just a word to the wise.The safety sensors MUST be mounted and wired before you can use the door and program it – this was a challenge for me because the door rails were pretty high, and the sensor brackets are not adjustable. I solved this by going to Lowes and having some 7 x 3/4″ pieces of wood cut, then mounting the sensors on them. Worked like a charm, but, the screws to mount the brackets are SMALL so holding the sensors up while also holding the screw and drill took no small effort. If possible, pre-drill your holes before mounting the sensors unless you already have some on there. I do NOT recommend mounting them on the door rails because the vibration will shake them off or out of alignment.Mounting was not too bad, I was able to use the existing mount for the main drive unit without issue, and the rail was a perfect fit from the old rail, so thankfully that worked out. As an aside, as we had an older home we had a direct wired opener and I was not sure how to handle that with the unit, but fortunately the red and white wires from the old wall opener matched up with the red and white tension sockets in the motor unit, so I popped them in and it worked like a charm.If you do NOT have the sensors wired AND the wall mount wired, you will likely not be able to program the door. As others have said, and I agree, you must fully cycle through the programming BEFORE doing the wifi. If you have issues with the programming, I recommend you unplug and restart the unit. It may take a couple of gos before you get it, but it does work in the end.Extra tools I recommend you get – wire strippers (for the sensor wires), wire stapler and wire staples (4-6mm should do easily), extra screws for the tensioner (I think they are 8×1/1/4 but the page give them), 7/16 and 1/2 sockets, same size manual wrenches for tightening the chain, and of course some patience.With all my set backs this took about 6 hours but now that I know how to do it it should be closer to 4 (this includes removing and breaking down the old units too).Hope this helps!

The installation was easy because I only had to replace the opener and install the safety beams on my door’s rail. Only negative comment was, I only got 10 staples to hold the safety beam wires in place ( minium of 20 is needed to do the job right ! )

De buen tamaño, se siente bien armado, mi segundo motor craftsman, el anterior me duro 15 años y lo quite para mandarlo a mantenimiento, asì que aùn tiene muchos años por delante, por eso mismo me decidì por otro motor craftsamn, es silencioso, y lo que mas me agrado es que es fàcil de reemplazar y que ahora se puede operar por wifi, feliz con el producto, muy recomendado

funciona muy bien, como es esperado
