Figure 11. Disconnect sensor connector.
5. Access the machine control electronics.
See Accessing & Removing the Electronic
Assemblies. Remove the connector P13
from the circuit board. Check the main
harness connections between the sensor
connector and machine control for a short
or open circuit.
• Replace the main harness if neces-
sary.
• If the harness is okay, continue with
step 6.
6. Measure the resistance across the out-
ermost contacts of the sensor connector
that includes the two MOVs.
• If a small resistance is measured, check
for debris across moisture strips inside
of the drum; clean if debris is present.
If debris is not present, replace sensor
harness with MOVs.
• Otherwise go to step 7.
7. Measure the resistance across each of
the outermost contacts and the center
terminal (ground connection).
• If a resistance less than infinity is mea-
sured, replace the sensor harness with
MOVs.

8. If moisture sensor diagnostic test passes,
check the thermistor: Perform TEST #4a.
• If the problem persists after replac-
ing the moisture sensor, harness with
MOVs and thermistor, replace the ma-
chine control electronics.
TEST #6 Buttons and Indicators
This test is performed when any of the follow-
ing situations occurs during the Console But-
tons and Indicators Diagnostic Test:
• None of the indicators light up
• No beep sound is heard
• Some buttons do not light indicators
None of the indicators light up:
1. See Diagnostic Guide/Before Servicing.
2. Perform TEST #1 to verify supply con-
nections.
3. Perform TEST #2.
4. Perform steps in Accessing & Removing
the Electronic Assemblies, and visually
check that the P5 connector is inserted
all the way into the machine control elec-
tronics.
5. Visually check the user interface assem-
bly connections.
6. If both visual checks pass, replace the
user interface assembly.
7. Plug in dryer or reconnect power.
8. Perform the Console Buttons and Indica-
tors Diagnostic test to verify repair.
9. If indicators still do not light, the machine
control electronics has failed:
• Unplug dryer or disconnect power.
• Replace the machine control electronics.
• Plug in dryer or reconnect power.
• Perform the Console Buttons and Indi-
cators Diagnostic test to verify repair.
