Automatic Temperature Control Test
This test checks the water inlet solenoids, the temperature sensor and the control board.
•
Check that the hot and cold water fill valves are working.
NOTE:
This test
MUST
be done with the Automatic Temperature Control (ATC) selected.
If the fill valves are working properly:
→

→
Press NORMAL or HEAVY DUTY cycle.
→

→
→
→
Press the WATER TEMP selector to set the wash water temperature to WARM.
→
→
→
→
→
Press START
→
→
→
→
→
After water has been introduced into the tub, press STOP/CANCEL once.
→
→
→
→
→
Measure the water temperature. At the WARM setting, the ranges should be 90-110°F.

If the winding measurements are much higher than shown in the preceding table, a problem
exists in the motor winding or in the wiring harness between the motor controller and the motor.
Check the resistance of the windings at the motor. Remove the connector at the motor and
take measurements as shown:
•
If the resistance is much higher than shown, replace the drive motor.
•
If the resistance at the drive motor is correct, there is a harness problem between the motor
and the motor controller. Replace the wiring harness as necessary.
If the temperature is not within this range, check the Automatic Temperature Control Sensor:
→
→
→
→
→
Remove connector P13 from the control board.
→

→
→
→
Measure the resistance between P13-7 and P13-8 at the wiring harness connector. The resis
tance should be between 74 K
Ω
and 24 K
Ω
.
