Outer Tub And Suspension Assembly; Thermistor/Atc Control (Auto Temp) - GE WPGT9350 Technical Service Manual

Thermistor/ATC Control (Auto Temp)

• The control uses a water temperature sensor
(thermistor) to regulate the wash water
temperature.
• The thermistor has a negative temperature
coefficient (as temperature increases,
resistance decreases).
• The thermistor is located in the bottom of the
outer tub under the wash basket.

Thermistor
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 accordingly.
The washer control should maintain the water
temperature in the tub within +/- 5°F (3°C) by
opening or closing the hot and cold water valves.
The thermistor has an approximate resistance
value of 121K Ω at 70°F (21°C).
Approximate resistance values at:
60F° (16C°) - 141K Ω
•
80F° (27C°) - 86K Ω
•
105F° (40C°) - 48K Ω
•
120F° (49C°) - 35K Ω

Resistance can be measured at the purple 2-pin
connector on the inverter board. Make sure to
unplug the connector to isolate the thermistor
before taking resistance readings. (See
and Main Board Pin Connectors.
To remove the thermistor:
1. Remove the 4 Phillips head screws (2 on
each side) that hold the back cover in place.
Remove the back cover.
2. Disconnect the wiring connector at the
thermistor.
3. Remove the 2 Phillips head screws that hold
the thermistor to the bottom of the outer tub.
Remove the thermistor.

Outer tub and Suspension Assembly

The wash basket, outer tub, and motor are
suspended by four rod and spring assemblies.
The rod and spring assemblies are attached to
each corner of the washer cabinet. They extend
down and connect to the bottom of the outer tub.

To remove the outer tub:
WARNING: The outer tub assembly is heavy and
requires two people to remove it from the washer
housing. Care should be taken when removing
and installing the outer tub assembly.
1. Remove the
Top Cover
2. Remove the drain hose from the outer tub:
Note: Water will remain in hoses even when the
tub appears empty. Use care to avoid water spills.
a. Squeeze the clamp and slide it back.
b. Carefully break the hose loose.
c. Remove the hose.
