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.
