Motor Assembly - GE Profile WPGT9150 Technical Service Manual

3. Lift the outer tub up and disengage the
suspension rod assemblies from each corner of
the outer tub.
4. Pull the outer tub assembly out of the washer
cabinet.
Caution: Care must to taken when reinstalling and
sealing the drain hose to the outer tub to ensure
there is no water leakage.
When installing, apply a thin coat of sealing
compound (part no. WH60X15) to the inner surface
of the drain hose.

Motor Assembly

• The washer has a direct drive pulse width
modulation motor that does not utilize a belt,
transmission, or mechanical brake.
• The motor assembly is composed of a coil
wound stator, Hall sensor, and permanent
magnet rotor.
• The motor varies speed and torque when the
pulse width modulated voltage from the inverter
changes frequency.
• The motor reverses rotational direction when
the inverter reverses electrical polarity to the
motor.
The washer motor has an approximate resistance
value of 8 Ω between any two of the three wires:
• Blue to red - 8
• Red to yellow - 8
• Blue to yellow - 8
Resistance can be measured at the yellow, 3-pin
connector on the inverter board or at the motor. (See
