Figure 11. Disconnect sensor from wire
harness.
6. Access the machine control electronics. See
Accessing & Removing the Electronic Assemblies,
page 21. Remove connector P13 from the circuit
board. Check the main harness connections
between the sensor harness and machine control
for a short or open circuit.
Replace the main harness, if necessary.
If harness is OK, continue with step 7.
7. Measure the resistance
across the outermost
contacts of the cable that
includes the two red MOVs.
If a small resistance is measured, check for
debris across moisture strips inside the drum;
clean if debris is present. If debris is not present,
replace sensor harness.
If a small resistance is not measured, continue
with step 8.

8. Measure the resistance across
each of the outermost contacts
and the center terminal (ground
connection).
If a resistance less than infinity is measured,
replace the sensor harness.
9. If moisture sensor diagnostic test passes, check
the thermistor: Perform TEST #3a, page 17.
If the problem persists after replacing the
moisture sensor and thermistor, replace the
machine control electronics.
TEST #4a Adjusting
Customer-Focused Drying Modes
NOTE: If the customer complains about the
clothes being consistently damp on automatic
cycles and the moisture sensor passed TEST #4,
step 3, the total auto dry time can be changed
by choosing one of 3 different Customer-Focused
drying modes:
1 = standard auto cycle
2 = 15% more drying time
3 = 30% more drying time
1. Be sure the dryer is in standby mode (plugged
in with all indicators off, or with only the DONE
[on some models] or COMPLETE [on some
models] indicator on).
2. Activate the Customer-Focused Drying Mode
by pressing and holding the TEMP button for
more than 6 seconds.
3. On models with seven segment display, the
dryer will beep and cf will be displayed for 1
second followed by the current drying setting.
On models without seven segment display, the
dryer will beep and the current drying mode
will be seen on the STATUS indicators. The factory
default value is "1".
4. To select a different drying mode, press
the TEMP button again. On models with seven
segment display, the dryer display will flash
and show 2, 3, or 1. On models without seven
segment display, STATUS indicators will indicate
the current selected drying mode.
On models without seven segment display:
1 = WET indicator lit constantly or flashing
2 = WET and DAMP indicators lit constantly
or flashing
3 = WET, DAMP, and COOL DOWN indicators
lit constantly or flashing
NOTE: On all models, while cycling through the
settings, the current setting will not flash, but the
other settings will.
