3255 Contractor Series 1/2 HP Chain Drive 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.
