each valve.

Resistance across each valve............. Approximately 1000 Ω±10%

40058901 Timer Verify input and output voltage is

present.

Verify wiring is correctly connected to

the timer.

See timing sequence chart for functional

description of the component.

Pressure switch Do not disconnect the pressure hose

from pressure switch to perform

measurements.

Measure resistance across the

following terminals on the pressure

switch:

Terminal 1 to 2................................

Terminal 1 to 3................................

Refer to wiring diagram/schematic for

correct contacts.

Air pressure that actuates switch is

determined by the water level of the

tub.

40116402 Motor Type of motor:

Two speed See following section “Internal Motor

Diagram and Schematic” for correct

wiring contacts.

40084501 Capacitor Discharge Capacitors

Remove wires from capacitor

terminals and connect ohmmeter,

set on highest resistance scale to

terminals.

Also check between each terminal

and capacitor case.

Between Terminals: Meter should

momentarily deflect towards zero then

return to over 5 MΩ. If no deflection

occurs, or if continuous deflection occurs,

replace capacitor.

Terminal to Case: Infinite resistance

40040301 Drain pump Verify drain pump is not clogged or

damaged. Remove clog and verify proper operation.

Replace drain pump if damaged.

40032701 Transmission

assembly Type of transmission:

710 rpm Externally identical, must be identified by

part number.

If transmission locks-up, replace.

40053601 Drive belt Type of drive belt:

710 rpm

Refer to “Parts Manual” for proper

pulley size.

Refer to “Parts Manual”, to verify which

drive belt and pulley size is required.

40098701 Power cord Measure resistance of wires. Continuity should be indicated on each

wire.

Verify polarity and grounding.
