TEST #4c Thermal Cut-Off
If the dryer does not produce heat, check the
status of the thermal cut-off.
1. Unplug dryer or disconnect power.
2. Access the thermal cut-off by first remov-
ing the back panel. See Removing the
Back Panel.
3. Using an ohmmeter, check the continuity
across the thermal cut-off. See Figure 10
for location.
• If the ohmmeter indicates an open cir-
cuit, replace the failed thermal cut-off
and high limit thermostat. In addition,
check for blocked or improper exhaust
system.
TEST #4d Gas Valve
1. Unplug dryer or disconnect power.
2. Access the gas valve by removing the
front panel and drum assembly. See Re-
moving the Front Panel/Drum Assembly.
3. Use an ohmmeter to determine if a gas
valve coil has failed. Remove harness
plugs. Measure resistance across termi-
nals. Readings should match those shown
in the chart. If not, replace the coil.
Terminals Resistance
1 to 2 1365 ± 25
1 to 3 560 ± 25
4 to 5 1220 ± 50
IMPORTANT: Be sure all harness wires are
looped back through the strain relief after
checking or replacing coils.
TEST #5 Moisture Sensor
NOTE: This test is started with the machine
completely assembled.

This test is performed when an automatic cy-
cle stops too soon, or runs much longer than
expected.
NOTE: Dryer will shut down automatically af-
ter 2-1/2 hours.
The following items are part of this system:
• Harness/connection
• Metal sensor strips
• Machine control electronics
1. Activate the diagnostic test mode and
advance past saved fault codes.
2. Open the dryer door. If a continuous beep
tone is heard and an alphanumeric num-
ber is displayed on the console as soon
as the door is opened, a short circuit ex-
ists in the moisture sensor system.
• If this doesn't happen, go to step 3.
• Otherwise, go to step 4.
NOTE: Over drying may be caused by a
short circuit in the sensor system.
3. Locate the two metal sensor strips on the
inside of the dryer. Bridge these strips
with a wet cloth or finger.
• If a continuous beep tone is heard and
a software revision number is displayed
on the console, the sensor passes the
test. Go to step 8.
• If not, continue with step 4.
4. Access the moisture sensor wires:
• Remove the back panel. See Remov-
ing the Back Panel.
• Remove the lint screen.
• Remove the two wires holding the lint
screen to the top.
• Remove the four screws from bottom
of the duct in rear. See Figure 10.
• Remove the duct from the dryer to ac-
cess the moisture sensor.
• Disconnect the sensor connector. See
Figure 11.
