To check temperature sensor at component
terminals, perform the following steps:
1. Unplug washer or disconnect power.
2. Disconnect the wire connector from the

temperature sensor.

3. Set the ohmmeter to the R X 1K scale.
4. To check the temperature sensor, touch
the ohmmeter test leads to the sensor
