The timer is located in the control console on
the back. It is composed of a series of switches
driven by an electric timer motor. The timer
motor rotates a pinion gear which then rotates
internal cams. As the cams rotate, they lift
and drop various switch contacts which ride
on the cam. The internal switches provide
cycle sequence or step inputs to the machine
control to control the pump, dispenser wax
motors, delay light, ON light and timer motor.
The timer wire harness connector can be
pulled and the individual contacts for the vari-
ous circuits can be checked with an ohm
meter. As illustrated, timer contact for the
drain pump is 14T

(Figure 2-1).
You can identify the wire for the drain circuit
(Figure 2-2)(Figure 2-2)
(Figure 2-2)(Figure 2-2)
(Figure 2-2)
by tracing down the side of the
connector to contact 14, and across to align
with column T.
Contact 8B in the connector is a direct con-
tact to the neutral leg of the timer. When an
ohm meter probe is placed into the 14T con-
nection and the other probe is placed into 8B,
an ohm reading of the complete drain circuit
can be performed. The drain circuit should
have a resistance of approximately 18 ohms.
This is the resistance reading of the pump

As stated previously, the machine control
board receives inputs from the timer monitor
where the timer is in the cycle. The machine
control board accomplishes this by routing
four circuits through the timer. Two of the cir-
cuits (1A & 1B) are supplied with 120 VAC and
the other two circuits (2A & 2B) are 24 VDC.
The voltages for the four circuits is shown on
the timer chart of the electrical schematic
enclosed in the washer console.
motor windings. The following chart can be
used for checking other components via the
timer wire harness connector.
