The Liftmaster 8500 wall mount garage door opener installs easy and provides a smooth and quiet operation, with a soft start and close feature. The unit requires a 110v receptacle within the reach of the ~ 6' cord. It uses a simple coupler to connect it to the torsion bar. It then turns the bar which turns the drums at each end, which use the cables to raise and lower the door. So be sure all related parts are in good working order because the cables are now doing all the lifting. No more center mounted door opener with track and chain or belt to lift the door. Frees up a lot of space and creates a clean look. The instructions say to install the opener with coupler attached to the torsion bar, then plumb the opener and secure in place with the included wall bracket. I suggest not worrying about being plumb, in case the torsion bar is not level. Let the opener hang naturally with the coupler tightened and lock in place with the mounting bracket. If you have to push the opener into plumb you are putting strain on the unit and the torsion bar end bearing. Otherwise, take the time to level the torsion bar after carefully releasing the tension on the torsion springs. The kit comes with the opener, safety sensors and brackets, a wall mount switch, a cable tension monitor switch, a lock solenoid, a ceiling light, a car remote, a hardware package, and wiring.The included wiring for the wall mount switch didn't reach. Ten more feet would be nice. Also, I found it odd that Liftmaster only includes one cable monitor switch that will stop the opener movement if the cable gains slack. What if the other (unmonitored) cable has a problem? The ceiling light requires 110v, which I was able to use the existing power that was for the old opener. The light is activated wirelessly when the opener comes on, and can also be activated from the wall mounted switch which has a built in motion sensor. A nice feature. The lock solenoid requires a 3/4" hole in the metal track. I suggest using a step drill. Its safer and creates a cleaner hole. The unit programs easily, and my original remote outdoor keypad was able to sync up with the unit. Good features, easy installation, and frees up ceiling space. Two thumbs up.Read full review

I am always upgrading my garage, this unit seemed like a good replacement for my old standard garage door opener that was on the fritz. Did my own self install. I'm a big DIY guy, can fix just about anything, so it wasn't that hard, but like anything, takes some time. Installing the head unit is the easiest part, but then you have to run all the wires and understand how the limit switch device works and where to mount it. It's super easy, but for a first time install, it takes some time. If you did this every day, you would zip right through it. I love the locking mechanism on the wheel channel, get one of those tapered drill bits that does all the different sizes to drill those holes. It doesn't need to be installed, I didn't install it unit I got the drill bit a week later. I had some issues setting up the limits, not that it was hard, but just hard to understand it initially, once understood, it takes 5 minutes to set up the travel and the force limit. It only took me 30 minutes to understand how to press those little buttons to get it into each mode and then stop it at the correct place for the limits, in the end, I had to stop it before I thought when it was almost closed. The downside of this unit is that you probably don't have an outlet near it, so you'll have to run one. In the end, it took me about 4 hours to install the garage door opener, the wiring took longer than to install the head unit. I then had to run an outlet to it the following weekend. I like DIY, and the garage door opener ROCKS! It leaves the old styles behind. The only con I can think of is that it doesn't seem to have a long range for the opener as compared to my old one and it takes time to get used to it because once it receives a commend to open, it unlocks the locking mechanism, then starts opening the door, accelerates it, then comes up to normal speed. So you don't think it's opening, but it is. You get used to that after a week or so. Overall, I am very happy that I upgraded to this opener and would buy it again.Read full review

I installed the lift master 8500 in 2 hours.now I have plenty of room to park a car on my lift for storage.the motor is very quiet.and the auto lock feature is great. would never go back to the old style opener. I would recommend it to any one needing a new garage door opener.or needing more overhead room. cost a little more but its worth it.plus great quality.

This 8500 is the smoothest, quietest door operator I'ves seen. Soft start and stop cause less wear on hinges and shaft, timer and alarm work well. Clickers were easy to program and also run my main garage door so only one is needed in each vehicle. A real asset to my shop.

Used for a door where a conventional tract style opener would not fit. Nice compact design and programming features. Quiet operation. Slight delay in opening due to the safety lock feature. If the opener lasts as advertised I will be very satisfied. Watching U-tube installation was also helpful.
