We have many customers that own a LiftMaster/Chamberlain garage door opener as the vast majority are compatible with GarageMate. But some models made after 2011 are not. Newer Liftmaster/Chamberlain models have the manufacturing date clearly printed on the garage door opener. If it is manufactured in 2011 or later (or if you are uncertain of the manufacture date), you can determine compatibility by the color of the "learn" button near the wiring terminals. If it is yellow it is NOT compatible. But if it is any other color like red, blue, purple, etc, it is compatible. See the photo below.
