Thermistor

The thermistor is located under the tub and is
attached to the back side of the sump with two
Phillips-head screws (5mm hex-head).
During the hot wash cycle, the thermistor senses
the water temperature and turns the heating
element on.
Note: If the thermistor is not operating, the hot
wash cycle will default to a set time for the heating
element to cycle.
The thermistor has a negative coeffi cient. As
the temperature at the contact point on the tub
increases, the thermistor's resistance decreases.
The thermistor has an approximate resistance value
of 50 K at room temperature.
To remove the thermistor:
1. Disconnect power.
2. Remove the outer door panel. (See
Panel.)
3. Remove the 2 Phillips head screws, washers,
and the access panel.
