The thermistor is located inside the turbidity
sensor. The thermistor monitors water
temperature in the tub. If the thermistor opens or
shorts it will cause an error (see
Consumer Error
Mode
in the
Electronic Controls
section of this
service guide). If it fails in open or shorted, the
control will default to the longest time algorithm.
Thermistor Specifications
To check the thermistor, access the Main Control
(see the
Electronic Controls
section of this
service guide), check resistance on connector
J806, pin 11, CX to pin 8, NX. The sensor may
also be removed and the two outside terminals
may be checked. Use the table above to
calculate the correct resistance reading.
