MOISTURE SENSOR

Refer to page 4-15 for the procedure for ser-
vicing the moisture sensor.
Perform this test if the dryer shuts off too soon
when set to an automatic cycle.
1. Set the dryer to the "Diagnostic Test Mode"
(refer to the procedure on page 6-1).
2. Open the dryer door.
3. Place a finger across the two metal sen-
sor strips on the lint screen housing. If a
beep tone sounds and "03" is displayed
in the console window, the sensor is work-
ing normally.

4. If the moisture sensor fails the diagnostic
test, check the moisture sensor wiring. Dis-
connect the power to the dryer, use an
ohmmeter, and check the yellow-red and
black wires for shorts (continuity to
ground), first with no load (wire connector
disconnected), and then with a load (con-
nected).
5. If the diagnostic test passes, perform the
thermistor test (refer to page 5-5).
6. If the problem still exists after replacing the
thermistor, check the ribbon connections
from the control panel to the machine con-
trol electronics board.
7. If all of the above are satisfactory, replace
the machine control electronics board.
