STEP 1: Turn off and unplug the treadmill from its power source.
STEP 2: Remove all screws from the base of the treadmill frame.
STEP 3: Take a photo (or make a note) of the control board so you can reference the wire positioning.
STEP 4: Unplug all of the wires from the control board optional (pliers to remove wires).
STEP 5: Remove the securing screws that connect the control board to the frame.
STEP 6: Remove the control board and insert the replacement board.
STEP 7: Secure the replacement board to the frame of the treadmill.
