Inverter Motor AC (IMAC) Removal
The Inverter on some models are part of the motor. If
the inverter should fail, replace the motor assembly.
1. Remove the plastic wire tie that holds the motor
wiring in place.
2. Remove the wire harness.
3. Remove the motor. (See the Washer
Components, Motor Assembly section in this
guide.)
Motor Assembly
The motor assembly consists of a reversible, variable
speed, 3-phase induction DC motor, and sensor. The
motor drives the tub drive pulley with a 7-rib belt.
The sensor monitors motor rpm and is connected to
the control board. The motor assembly is checked
from the front of the washer and removed from the
rear.
Motor Assembly Diagnosis
1. Remove the service panel. (See the Washer
Components, Service Panel section in this
guide.)
2. Disconnect the motor wire harness.
On the motor plug, check for an approximate
resistance value of 6 ohms between any two of
the three wires:
• Blue to white - 6 ohms
• Blue to red - 6 ohms
• White to red - 6 ohms
• The sensor has a resistance value of
approximately 118 ohms between the two
orange wires.
Operation of the motor assembly can be checked by
using service test modes t10, t11, and t14. (See the
Service Test Mode section in this guide.)
