3. Locate the two metal sensor strips on the
face of the lint screen housing. Bridge
these strips with a wet cloth or finger.
• If a beep tone is heard and a software
revision number is displayed on the
console, the sensor passes the test. Go
to step 4.
• If not, unplug dryer or disconnect
power.
• Access the moisture sensor wires by
removing the toe panel. See Removing
the Toe Panel. Disconnect the sensor
wires from the harness. See Figure 12.
Go to step 9.

4. Unplug dryer or disconnect power.
5. Access the machine control electronics.
See Accessing & Removing the Electronic
Assemblies. Remove the connector P13 from
the circuit board. Measure the resistance
across terminals 1 (yellow-red wire) and 2
(yellow-red wire). See Figure 17.

• If the ohmmeter does not indicate (infin-
ity) open circuit, go to step 6.
• Otherwise, measure the resistance across
between pins 1 and 2 of connector P13 on
the machine control board. If a resistance
less than 1 megohm is measured (with
analog or digital ohmmeter), inspect the
control board for any debris bridging these
pins. If no debris, replace the machine
control electronics.
6. Access the moisture sensor by removing
the toe panel. See Removing the Toe
Panel. Disconnect the sensor from the
wire harness. See Figure 12.
7. Measure the resistance across the outer-
most contacts of the cable that includes
the two red MOVs.
• If a small resistance is measured, replace
this component (Wire Harness, Moisture
Sensor).
• Otherwise, go to step 8.
8. Measure the resistance across the pins of
the mating connector.
• If a small resistance is measured here,
replace this harness (Digital Wire
Harness).
9. Measure the resistance across each of the
outermost contacts and the center terminal
(ground connection).
• If a resistance less than infinity is
measured, replace this component (Wire
Harness, Moisture Sensor).
