before
servicing
any
electrical
component,makingohmmeterchecks,or replacingany parts.,
All voltage checks should be made with a voltmeter having a full scale range of
130 volts or higher.
After service is completed,
be sure all safety-grounding
circuits are complete, a!t
electrical connections
are secure, and all access panels are in place.

period.
If the pump motor fails to operate during the first cycle increment,
check for
power at the pump motor connector block, if there is no power check the door
latch switch, if there is power, check the pump motor as described
in this
section.

Let the timer
advance,
or index
it forward
to the
portion
of the
cycle
in
question..
If a component controlled by the timer fails to function as the timer advances
through the cycle, check for voltage at the timer terminals, tf the check voltage
is supplied to the component,
check the component
as described
in this
section
Continuity
through timer contacts,
other controls,
and wires can also be
checked with an ohmmeter with electrical power disconnected.
If the timers contacts fail to close in the sequence shown on the timer chart
are burned (have resistance measurable
with an ohmmeter),
or if timer does
not advance automatically,
replace the timer.
