Clutch Operation
• The clutch locks and unlocks the basket by
engaging teeth on the inside of the rotor with
teeth on the clutch coupler.
• When the basket and infusor are in the locked
position, the clutch moves downward and
engages the rotor and clutch coupler teeth
allowing the basket to rotate with the infusor.
• When the basket and infusor are in the
unlocked position, the clutch moves
upward, disengaging the clutch coupler and
rotor teeth, allowing the infusor to rotate
independently of the basket.
Clutch Motor
To diagnose the clutch motor:
• The inverter supplies 120 VAC to the clutch
motor through the brown and white wires
when the clutch motor changes position.
Note: Disconnect power and unplug the clutch
motor connector at the inverter board.
• 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
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.
• When the clutch is in the unlocked position
the switch should be closed (0 Ω).
• When the clutch is in the locked position the
switch should be open (infinity).
