Tub Thermistor
The tub thermistor is located under the tub and is
attached to the left side of the sump with 2 lock
tabs. A thermal mastic is applied to the fl at side
of the thermistor where it makes contact with the
underside of the tub.
During the hot wash cycle, the thermistor senses the
water temperature and turns the heating element
off when the water reaches 128°F.
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
56.5K Ω at 72°F.
To remove the thermistor:
Note: Wear latex gloves to perform this repair.
