If the thermistor resistance checks within •
normal limits, replace the machine control
electronics.
TEST #3b Thermal Fuse Test
ELECTRIC DRYER: The thermal fuse is wired
in series with the dryer drive motor.
GAS DRYER: The thermal fuse is wired in
series with the dryer gas valve.
ALL DRYERS:
1. Unplug dryer or disconnect power.
2.Accessthethermalfusebyrstremoving
the toe panel. See Removing the Toe
Panel; and for thermal fuse location see
Figure 11.
3. Using an ohmmeter, check the continuity
across the thermal fuse. See Figure 11 for
location.
If the ohmmeter indicates an open circuit, •
replace the failed thermal fuse.
TEST #3c Thermal Cut-Off Test
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rstremov-
ing the toe panel. See Removing the Toe
Panel.
3. Using an ohmmeter, check the continuity
across the thermal cut-off. See Figure 11
for location.
If the ohmmeter indicates an open circuit, •
replace the failed thermal cut-off and
high limit thermostat. In addition, check
for blocked or improper exhaust system,
or failed heat element (electric dryer).
TEST #3d Gas Valve Test, Gas Dryer Only
1. Unplug dryer or disconnect power.
2. Access the gas valve by removing the toe
panel. See Removing the Toe Panel.
3. Use an ohmmeter to determine if a gas valve
coil has failed. Remove harness plugs.
Measure resistance across terminals.
Readings should match those shown in
the following chart. If not, replace coil.
Terminals Resistance
1to2 1365 Ω± 25
1to3 560 Ω± 25
4to5 1220Ω±50
IMPORTANT:
Be sure all harness
wires are looped back
through the strain
relief after checking or
replacing coils.

TEST #4 Moisture Sensor Test
NOTE: This test is started with the machine
completely assembled.
This test is performed when an automatic
cycle stops too soon, or runs much longer
than expected.
NOTE: Dryer will shut down automatically
after 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 beep tone is
heard and an alphanumeric number is
displayed on the console as soon as the
door is opened, a short circuit exists 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.
