This step-by-step washer repair guide shows how to replace the machine control board on a front-load washer. The machine control board manages the washer's cycles such as wash, rinse, drain and spin by communicating with components such as the drive motor and pump and activating them as needed. If the machine control board is completely dead or doesn't activate components properly, replace it with a manufacturer-approved replacement part.
This procedure shows how to replace the machine control board (also known as the main electronic control board or mother board) in Kenmore, LG, Whirlpool, Maytag, Samsung, GE and Amana front-load washers.
