8165 / (Replaced 3255) Contractor Series 1/2 HP Chain W/O Rail Assembly

Fit perfectly. The automatic setup for travel and torque was outstanding. The myQ app was easy and worked perfectly. I sent an invite to my wife and it installed just as easily. I replaced both of our 12 year old openers so these comments apply to both. No difference . Very pleased. Update 3/26/2024- I have intermittent issues with one opener not closing all the way but going back up. I think it is a torque setting too sensitive but this is the down side of automatic settings I guess.

Purchased this 3255 contractors model to replace a 2265-67 professional model that was installed originally in 2004 .. I was very satisfied, really quick 2 day delivery. Quick and easy removal and installation of the motor head all screws and connectors were identical. Programming was a little challenge primarily because the manual did not clearly show the learn button sequences and they were physically hard to see, received a better view from the website and was able to get the thing programmed. Overall I’m satisfied

A lightening storm fried our current lift master opener. We bought this one. After reading reviews we were expecting a 4 hour job. This one literally was a direct bolt in to our old one. Took my husband 45 mins to get up and running. Uses our current sensors and everything. Very happy with our purchase.

First, this is simply a replacement for your existing motor. You'll need to have an existing rail and chain. The unit has hardware, safety eyes, one remote, and a mounted switch. The only downside is that there isn't an installation manual in the box, but you can easily find one online. It took me 30 minutes to mount this, including removing my old unit and connecting this new one. I used all the existing wiring which took longer because I had to strip them all. This uses the push style connections which are more fickle than the screw ones in my experience. The only problem I had was that I didn't set my limits prior to trying it. I was getting an error that the eyes were not aligned or there was a short. But the receiver was glowing green so I knew it was good. Only after installing the app did I see that the unit thought it was in the opposite position it was in. Adjusting the limits solved the problem So use the app. The other downside is the app isn't compatible with siri or google home. But it's not a deal breaker.

Direct fit for my 17 year old Liftmaster. Package came promptly and in good condition. Negative issues are the MyQ ap. and remote programming. I created an account but get nothing but the wheel of death after logging in. Tried everything trying to log in but no luck. Also could not program my old remotes. Other than that the opener works well.

I bought this unit instead of buying the typical $20 to $35 replacement parts for the metal drive gear, washers and plastic worm gear. I figure it was better to buy this entire unit which came with a new logic board, new gears and the like so that I have the peace of mind that I dont have to replace any other old parts on the old unit (this includes any of the safety sensors and the like). Also, this package included a remote, so now I have another one to use along with the old unit and another wall unit button as well to use that I can put it closer to the inside portion of the garage door for more options. If you have the money to spare, this was more of a time saver and you do get 1 more remote to use. Definitely a plug and play approach to replace a broken 3255 unit.

Since the day I've got it, with no door attached, only the chain, the lift master intermittently thinks its hit something and reverses. It'll usually take 5-10 attempts to close before it fully closes, EVERY.TIME. I've had it for years now and its never gotten better or worse, always have to waste about 5 minutes reclosing the door over and over and over every time we leave the house or come home through the garage, its infuriating and a huge waste of time. If I wasn't in a tight financial situation, I'd have replaced it years ago. My best guess is that whatever sensor it has for resistance is just set too low, but unlike every other garage door opener I've ever owned, it has no way to increase the allowed resistance, you can re-initialize everything (and I've done it many times) where it auto senses the resistance to expect, but obviously whatever method its using to auto determine what resistance is too much resistance is flawed and there's no means of over riding it. Again, this happens with out the door attached, I've tried getting the special chain grease and re-greasing the chain, but that had no impact either, the issue seems to be with the opener itself.

Opener arrived early which was fine. Easy to install and setup. Just read the instructions and follow them. You will need to use the included wall switch and remote. I had to order a separate remote as it only comes with one. When setting the down force for the door, stop about an inch from the floor. Great videos on YouTube.
