FOR SERVICE TECHNICIAN'S USE ONLY
IMPORTANT: To avoid damage to the gas burner
wire harness, ensure the harness is routed
exactly as it was prior to service.
10. Unplug dryer or disconnect power.
11. Reassemble all parts and panels.
12. Plug in dryer or reconnect power.
13. Perform steps under "Service Test Mode",
page 6, to verify repair.
TEST #5: Moisture Sensor
This test is performed when an automatic
cycle stops too soon, or runs much longer
than expected.
NOTE: Dryer will shut down automatically
after 2½ hours.
The following items are part of this system:
Part of Moisture System
Harness/connection
Metal sensor strips
Machine control electronics
NOTE: Refer to strip circuit on page 24
to diagnose moisture sensor.
NOTE: Overdrying may be caused by a short
circuit in the sensor system.
1. Unplug dryer or disconnect power.
2. Remove console to access the machine
electronics.
3. Access the moisture sensor wires by
sliding the top panel back and removing
the front panel. Disconnect the 3-wire
moisture sensor connector located below the
door opening between the front panel and
bulkhead.
4. Access the ACU and remove connector
P13 from the circuit board. Check the wire
harness for continuity between P13 and the
moisture sensor connector.
 If there is continuity, go to step 5.
 If there is no continuity, replace the main
harness.
DO NOT REMOVE OR
Electric Gas
Dryer Dryer
DESTROY
5. Measure the resistance across the
outermost contacts of the connector that
includes the two MOVs.
 If a small resistance is measured, clean the
two metal moisture strips inside the drum.
If a small resistance is measured after
cleaning, replace the sensor harness.
 If a small resistance is not measured,
go to step 6.
6. 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.
7. If the moisture sensor diagnostic test
passes, check the outlet thermistor: TEST
#4a, page 18.
 If the problem persists after replacing the
moisture sensor and thermistor, consider
adjusting the dryness level (see TEST #5a:
Adjusting Customer-Focused Dryness Level).
8. If the preceding steps did not correct the
problem, replace the ACU.
TEST #5a: Adjusting Customer-
Focused Dryness Level
NOTE: If the customer complains about
the clothes being less dry or more dry than
desired and the moisture sensor passes TEST
#5: Moisture Sensor, the total dry time can
be lengthened or shortened by changing the
Customer-Focused Dryness Level from "2"
(standard auto cycle) to a "3" (15% more drying
time), "4" (30% more drying time), "1" (15%
less drying time), or "0" (30% less drying time)
auto cycle.
1. In standby mode (dryer plugged in but not
powered up), press and hold the DRYNESS
or DRY LEVEL button for approximately 3
seconds.
