To install the heater:
Slide the heater assembly into the tub opening 1.
and inside the bracket attached to the outer tub.
Seat the heater assembly in the tub opening.2.
Place the thermistor wire thru the hole in 3.
the shield and place shield over the element
terminals and against the outer tub.
Install the 10-mm hex nut and use a torque 4.
wrench to tighten the 10-mm hex nut to 35 to
40-in. lbs. of torque.
CAUTION: Proper torque must be applied to the 10-
mm hex nut to assure a proper seal. Under torquing
could cause water leakage; over torquing could
cause the tub to crack.
Bracket
5. Connect the thermistor wire harness.
6. Connect the blue and red wires to the heater.
Place the heater wires inside the wire guide.
Note: Wire terminal under hex nut is not used.
7. Install the Phillips-head screw and the motor
wire harness clamp to the heater shield.
Thermistor
The control uses a water temperature sensor
(thermistor) to regulate the wash water temperature.
To determine the temperature of the incoming
water, the washer control measures the difference
between the voltage sent and the voltage returned
from the water temperature sensor. The washer
control then makes temperature adjustments by
activating the appropriate water valve.

The thermistor has a negative temperature
coeffi cient (as temperature increases, resistance
decreases).
Resistance can be measured at the thermistor wire
harness. Make sure to disconnect the wire harness
to isolate the thermistor before taking resistance
readings.
