Chamberlain Group documents the 888LM/889LM control-panel family for Chamberlain/LiftMaster Security+ openers manufactured after 1998 with purple or red/orange Learn buttons. Do not apply this to Security+ 2.0 yellow-button openers.
A same-brand or myQ label does not make 889LM universal. Verify the opener generation and manufacture date before ordering.
