16008373-01 SECTION 2. ELECTRICAL COMPONENTS & TESTING
Motor Windings Check
1. Disconnect power to the unit.
2. Remove each pair of phase wires from the
motor control and perform an ohm check
of each wire leading to the motor. Each
wire pair should show 2-3 ohms resistance
(Figure 2-5).
2. There should be no continuity between
any of the terminals and the frame of the
motor.
3. Check that all six motor terminals are se-
cure and at the same height in the con-
nector housing. Replace motor if termi-
nals are pressed into the motor.
4. Remount the six-position motor connec-
tor onto the motor. Reassemble the drip
shield cover onto the motor control.
5. Reposition the motor control into the
washer when finished. Make sure the two
screws and the twistlock wire ties are fas-
tened properly to the wire harness.
To gain access to the motor control board
terminals (Figure 2-6):
1. Disconnect power to the washer prior to
testing.
2. Remove the two screws securing the mo-
tor control assembly to the base. Unsnap
the two twist-lock wire ties restraining the
motor to the motor control board harness
base.
3. Remove the green ground wire, line & neu-
tral wires and the JP4 connector from the
motor control board.
4. Carefully lift the front end of the motor
control board to disengage the rear lock-
ing tabs from the slots in the base. Slowly
drag the motor control board, with motor
harness attached, toward the front of the
washer and place in front of the washer.
5. Remove the screw securing the splash
shield covering the face of the motor con-
trol board. Pivot the splash shield with top
screw in the motor control board metal
frame, allowing the plastic shield to be-
come an electrical shield between the
motor control board and the base.
6. Reconnect the ground wire, line 1 and neu-
tral wires. Leave the JP4 connector off the
board (Figure 2-6).
7. Place the timer knob into the delay
increments.
8. Plug the power cord into the wall socket
and press the push-to-start button.
9. Check Phase C by disconnecting the yel-
low or orange wire at the motor control
board. If the motor operates with a slight
growling sound, phases A and B are oper-
ating correctly. Reconnect phase C and
test with phase B disconnected. If the
motor does not run properly, phase A or
B is not functioning. Perform the motor
windings check (See Motor Windings
Check).
10. Check Phase B by disconnecting the white
or red wire at the motor control board. If
the motor operates with a slight growling
sound, phases A and C are operating cor-
rectly. Reconnect phase B and test with
phase A disconnected. If the motor does
not run properly, phase A or C is not func-
tioning. Perform the motor windings
check (See Motor Windings Check).
