STEAM GENERATOR TROUBLESHOOTING, continued
Serviceability is limited to testing components function and available voltages or
amperages. If any component fails, the steam generator must be replaced as an assembly.
The thermistor is a NTC (Negative Temperature Coefficient) device; as temperature goes
up, resistance goes down. The ohm value at room temperature is approximately 60K
Ώ
and the voltage measured across the sensor is approximately 3.6 V
DC.
AT 212ºF the ohm
value is approximately 3.3K
Ώ
and the voltage measure across the sensor is .88 V
DC.
The dryer is not connected to cold water
plumbing but relies on a water reservoir
and a pump motor. The water pump is
powered by the control board from
CON RD6, yellow (+9 V
DC
) to blue
(Ground).
To test the motor:
1) place your meter leads across the
motor connector,
2) remove the single connector from
the high water sensor (BN wire),
3) Start a steam cycle, and observe
your meter and listen for the motor
to run. If the control board is
powering the motor with 9 V
DC
and
the motor is running,
4) Reconnect the single brown wire to
the high water sensor. The control
board should sense the water is
touching the high water sensor and
turns the 9 V
DC
to the motor OFF.
