Microprocessor Board
Some models use a microprocessor
board to control the fill, agitate and spin
cycles instead of a mechanical timer.
The components involved with these
cycles are the microprocessor board,
transformer, water level switch, motor
relays and lid switch.
The control is divided into three main
areas: (1) the washer program
selection area, (2) the display and level
adjustment area, and (3) the washer
option selection area. Any legitimate
key selection is followed by a sound
from the audio device, the corre-
sponding display change, and the
appropriate machine response. Any
key selection which is not legitimate
prompts no response. The machine is
started by selecting a program.
The microprocessor board controls the
operation of the washer. It is an elec-
tronic circuit board that is located in the
console and is attached to the back of
the touch pad. It receives the data as
the user selects the type of cycle and
options by pressing the indicated areas
on the touch pad. The touch pad does
not function as a switch but as a menu
to make selections. Behind the touch
pad are switch actuators (push rods)
that actuate switches on the micro-
processor board when the user makes
the selections.
