Diagnosing the Clutch Motor
Note: Disconnect power and unplug the clutch
motor connector at the inverter board.
• The light blue connector on the inverter board
has the blue, white and brown wires that are
the clutch motor wires.
• The inverter supplies 120 VAC to the clutch
motor through the brown and white wires when
the clutch motor changes position.
• To check power from the inverter, program any
wash cycle and press START. If the clutch motor
was left in the locked mode there should be 120
VAC present for about 6 seconds on the brown
and white wires. If the clutch motor was left in
the unlocked mode, there should be 120 VAC for
about 6 seconds, then a pause with no voltage,
then 120 VAC again for about 6 seconds.
• The clutch motor has an approximate resistance
value of 2000 Ω. This can be measured
between the white and brown wires on the
inverter board. (See
Inverter and Main Board Pin
)
Connectors.
• The rotation of the clutch motor causes an
internal switch to open or close. This can be
measured between the brown and blue wires on
the inverter board.
