I have a Liftmaster 1/2HP "Security +" Model 1255R. CanI just replace the openee assembly with this one and re-use the controls and chain/rails?

Yes. You'll have to loosen the chain as you install the new unit, but it is an exact replacement. After installation, you'll have to re-program the remote.

Correct. You need one 888LM to replace each old opener button and you only need one gateway to plug into your router. They will work with any Liftmaster or Chamberlain opener 1998 or newer. The only difference between the Chamberlain and Liftmaster controllers is the nameplate, so buy the best price.

I think it should, but not sure. I replaced my 1995 model 1260LM with a new unit (liftmaster 3265-267) and it fits perfectly on the old chain and rail....my sprocket to sprocket distance is just under 11 ft. Only problem: short power cord, but that was easily remedied. Work great.

My unit has only been in service since Dec 2013. Everything works great. You may wont to call Liftmaster and ask them if there are any real differeneces.

The power door lock is only for the LiftMaster 8500 side mount operator. It is an additional lock that my managers do not think is really necessary. With any engaged operator, your door is secure and cannot be forced open from the outside. Hope that helps!Ryan M. Entry Systems

You can call liftmaster and ask them but I'm positive it will work. My liftmaster is from 2002 and it worked.

I am not familiar with your opener, but The LiftMaster 850 basically just makes a contact, the same as a doorbell type switch. If you have two wires that lead to a wall mounted switch, it's almost a certainty it will work. If you have a wiring diagram inside your current opener it may help you find a voltage source to operate the LiftMaster. If you have terminals for the doorbell switch wires on the outside of the opener, just follow the wires to the inside of your opener. This will tell you what wires need to make contact to operate your opener. Disconnect and run those two wires to the Liftmaster. Very easy.

The directions say compatible with "Liftmaster" does not say professional. Here is the number to call them and ask. 8004421255

Not sure, but very much doubt it if Learcar2U is not a Liftmaster model. But Homelink may have product compatiible with your .

As with most aftermarket openers, it will work with many LiftMaster models, mine included, but it won't work with all of them...and setup can be tedious.

You much be sure that you are replacing the ARMS for the "liftgate and /or window-lift". What I mean is, the window-lift is smaller and the Liftgate itself is larger. I purchased both and had to learn the hard way. As soon as you purchase them, just to make sure that you pair them up. Youtube can easliy walk you thriugh it also, it the manufactures link.

Hello Peter. I found the users manual for 985 family:http://chamberlain.custhelp.com/app/answers/detail/a_id/1135/~/liftmaster-model-985-owner's-manual-(includes-model-9851)According to this 971 should work for you. If you want to double check just see the color of the programming button on your opener. If it's red then you are fine (that drives the frequency it uses).

Hi! i did not find the assembly data for your model. If it a Liftmaster with some age (old machine), it may work. My problem was miss aligment of the optical sensor and a stuck RF command (remote) that strip the Gear on main shaft. The gear can be find on Amazon, it is low cost bout the shipping cost may be high for this repair. My LiftMaster work fine now so godd luck
