The vast majority of Chamberlain and LiftMaster garage door openers are compatible with GarageMate. (Skip to the Wiring Diagram section if your Chamberlain/Liftmaster was manufactured prior to 2011).
Unfortunately in 2011, Chamberlain and Liftmaster started shipping some garage door openers with the wall "switches" shown in the photo below.
The wall switches shown above are not really switches, they are small communication circuits that send complex signals when the button is pressed.
It is regretful that new Chamberlain/Liftmasters are no longer compatible with aftermarket accessories.
They could have taken the same approach of Genie garage door openers. New Genies supports both new computerized wall-switches AND traditional/standard switches.
Chamberlain/Liftmaster
patented the communication signals so we are reaching out to Chamberlain/Liftmaster to see how to legally add compatibility to their new models. The next section lists known incompatible models.
Chamberlain HD220,and 45DCBR5 are not compatible with aftermarket accessories like GarageMate.
Liftmaster 41D767, and 8075 are not compatible with aftermarket accessories like GarageMate.
Keep in mind the vast majority of Chamberlain/Liftmaster were made prior to 2011 and will be compatible with GarageMate. See the wiring diagrams below. We have marked the images below with a red and white arrow that indicate where to wire GarageMate"s RED and WHITE wires.
