Motor and Drive System
The new GE washers incorporate a new motor and drive system. The 120 VAC input powers a three phase
induction inverter/motor assembly. The inverter produces approximately 340 VDC, which is pulse width
modulated (PWM) to control motor speed. There is no location to check inverter output voltage to the motor.
Voltage given is for information only. The motor is bi-directional, constantly reversing it’s direction to provide
agitation. The motor is connected by a belt to the shaft and mode shifter assembly. By energizing or de-
energizing a coil, the mode shifter assembly engages or disengages the shaft and tube. This allows for
agitation and spin cycle modes.
Motor status is displayed through a series of flash codes from a green LED located on the front side of the
inverter just above the motor. These codes are stored in memory until cleared.
