7. Measuretheresistanceacross each
of the outermost contacts and the
center terminal (ground connection).

If a resistance less than infinity is
measured, replace the sensor harness.
8. If moisture sensor diagnostic test passes, check
the thermistor:PerformTEST #4a,pages13–14.

If the problem persists after replacing the
moisture sensor and thermistor,replace the
machine control electronics.
TEST #5a Adjusting
Customer-Focused Drying Modes
NOTE: If the customer complains about the
clothes being damp and the moisture sensor
passedTEST #5, step 3, the total dry time can be
lengthened by changing from a “CF1” (standard
auto cycle) to a “CF2” (15% more drying time) or
“CF3” (30% more drying time) auto cycle.The
consumer can access these drying modes via
the Sound & DIsplay menu under “Custom
Dry Level”.
1. Activate the Diagnostic Test Mode, page 2.
2. Select the Component Activation option.
3. From the list of available choices,select the
Customer-Focused Drying Modes option.
4. A new screen will appear that shows the
currently selected mode (CF1 by default) and
allows the selection of CF1, CF2, or CF3.
5. Press the “Save and Exit” button to save the
drying mode and exit to the ComponentActivation
menu.
6. The result will be saved in the EEPROM of the
control board, and will be retained after a loss
of power.
7. Exit diagnostics and power cycle the dryer
for the new setting to take effect.
