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.
There are 2 methods to check the motor assembly.
Method A:
1.
Remove the service panel. (See
Service Panel
.)
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
Ω
,
Blue to red - 6
Ω
,
White to red - 6
Ω
The sensor has a resistance value of approximately 118
Ω
between the two orange
wires.
Operation of the motor assembly can be checked by using service test modes t04,
t13, and t14. (See
Service Test Mode
.)
