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

TIMER

With the timer, user selects

the various

To Tegt Tt_eTinier

If the timer is suspected

of faulty

operation,

reference

timer chart and electrical

schematic

diagram

and proceed

as follows:

1. Index

the timer

to the first increment

of the normal

cycle, which

is a drain

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

let the timer motor advance

the timer through

the drain increment

to determine

if the timer

motor

and drive

train are fully

operative.

Let the timer

advance,

or index

it forward

to the

portion

of the

component,

check

the

component

as described

and wires

can

also

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.
