Do-It-Yourself Story

Removed old board and button modules,replaced with new. Easy fix..... two screws at the top, one for the side which drops out containing a circuit board behind it. Three screws holding it on. Take them out and separate the board from the side container by unplugging the button board module. There's a metal mounting shield held in by plastic clip posts, pry those apart gently and the circuit module is fully exposed for removal, which is also held in by plastic clips. Pry apart gently, remove old board and snap in replacement board. Button assembly is in the side piece and also held in place with plastic clips. Same procedure, pry clips gently, pop out old and snap in new buttons. Reverse the removal to reinstall.
