Electrical Shock Hazard Disconnect power before accessing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock. TEMPERATURE SENSOR & HEATER Temperature Sensor Heater Refer to page 4-22 for the procedure for accessing the temperature sensor & heater. To check the temperature sensor or heater at the component terminals, perform the following steps. 1. Unplug washer or disconnect power. 2. Disconnect the wire connector from the temperature sensor or heater. 3. Set the ohmmeter to the R X 1K scale. 4. To check the temperature sensor, touch the ohmmeter test leads to the sensor terminals. The meter should indicate as shown in the chart below.
