Test
Test 8: 1. Disconnect the plug from the drive motor
and measure the resistance pins 4 & 5
in the motor.
Test 9: 1. Remove the belt from the motor and spin
the motor pulley. Does the motor spin freely?
2. Spin the tub pulley. Does the tub spin
freely?
3. Disconnect the plug from the motor and
measure the resistance of the windings
(pin 1 to pin 2, pin 1 to pin 3, pin 2 to pin 3.)
All reading should be between 4 and 6 ohms.
Test 10: 1. Remove the belt from the motor and spin the
motor pulley. Does the motor spin freely?
2. Spin the tub pulley. Does the tub spin
freely?
3. Disconnect the plug from the drive motor
and measure the resistance between pins
4 & 5 in the motor.
4. Disconnect the plug from the motor and
measure the resistance of the windings (pin 1
to pin 2, pin 1 to pin 3, pin 2 to pin 3.) All
readings should be between 4 and 6 ohms.
Test 11: 1. Communication problem. Check the wiring
between the control board and the speed
control board.
Test 12: 1. Check the resistance of the NTC. Is it
around 50K ohms.
Test 13: 1. Have the power company check the
frequency of the incoming power. If correct,
replace the control board.
Steps
Test
Correction
If the resistance is between 105 -130 ohms, replace
the speed control board.
If the resistance is NOT between 105 -130 ohms,
replace the motor.
No. Replace the motor.
Yes. Go to step (3)
No. Check the tub bearings.
Yes. Go to step (3)
If the readings are correct replace the speed
control board.
If the readings are incorrect replace the motor.
No. Replace the motor.
Yes. Go to step (3)
No. Check the tub bearings.
Yes. Go to step (3)
If the resistance is NOT between 105 -130 ohms,
replace the motor.
If the resistance is between 105 -130 ohms, Go to
step (4)
If the readings are correct replace the speed control
board.
If the readings are incorrect, replace the motor.
Wiring bad. Correct wiring problem.
Wiring good. Replace the control board. If the
problem is not corrected, replace the speed
control board.
No. Replace the water inlet valve assembly
Yes Replace the control board.
