The table above shows the resistance
values that should be observed for the
various temperatures at the heater as-
sembly.
If the thermistor resistance does not
agree with the measurements in the
table, replace the inlet thermistor/ high
limit thermostat assembly.
If the thermistor resistance agrees with
the measurements in the table, replace
the machine control electronics.
TEST #4b Thermal Fuse
The thermal fuse is wired in series with the
dryer drive motor.
1. Unplug dryer or disconnect power.
2. Access the thermal fuse by first removing
the front panel. See Removing the Front
Panel/Drum Assembly, and for thermal
fuse location see Figure 10.
3. Using an ohmmeter, check the continuity
across the thermal fuse.
If the ohmmeter indicates an open cir-
cuit, replace the failed thermal fuse.

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 front panel and drum assembly.
See Removing the Front Panel/Drum As-
sembly.
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 inlet thermistor/high limit thermo-
stat. In addition, check for blocked or
improper exhaust system, or failed
heat element.
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 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.
