Remotes, Wall Controls & Installation Parts

The 893MAX universal remote replaces the discontinued Craftsman 139.53680, 139.53859 and 139.53879 remotes and works with every Craftsman opener made since 1993. Keypads and other remotes: Craftsman remotes. Wall buttons: openers built before 1998 take the 041C0494-2 control panel; 1998-and-newer openers take the 889LM. Door arms, brackets, bell wire, release rope and batteries: Craftsman wall controls and installation parts.

Craftsman openers are built by Chamberlain, so parts carry Chamberlain/LiftMaster numbers and may be printed with or without a leading zero (41A2817 = 041A2817). Wrong model? See all Craftsman models by number.
