4.
Measure resistance between the motor
relay common (COM) terminal and
ground. A high resistance (open) should
be measured.
➔
If it does not, perform the Thermal
Fuse Test and Door Switch Test and
check harness continuity. If they test
good, replace the motor.
Door Switch Test
1.
Unplug dryer or disconnect power.
2.
Check door switch continuity. Neutral to
P2-6 on the electronic control should
read closed with the door closed, and
open with the door open.
3.
Otherwise, verify harness continuity.
➔
If no continuity, repair or replace the
harness.
➔
If harness is good, replace the door
switch.
Temperature Switch Test
1.
Unplug dryer or disconnect power.
2.
Remove the wires from the switch to
complete this test.
3.
Reference contact continuity with
Pins 1 and 2 to Pin 4 (White).
4.
Reference contact continuity with Pin 3
to Pin 5.

Test
1.
Unplug dryer or disconnect power.
2.
Remove the wires from the switch to
complete this test.
3.

High Limit Thermostat Test
1.
Unplug dryer or disconnect power.
2.
Remove the high limit thermostat and
check continuity. Refer to the Thermal
Components illustration above right.
➔
If open, replace the high limit
thermostat.
➔
If closed, apply heat. It should open at
about 250°F (121°C). Otherwise,
replace the high limit thermostat.
Thermal Cut-Off Test
This unit is equipped with a “one-shot”
thermal cut-off. See Thermal Components
illustration above. If the dryer does not heat
with power supplied:
1.
Unplug dryer or disconnect power.
2.
Check the thermal cut-off for continuity.
➔
If open, thermal cut-off has failed and
must be replaced.
NOTE
: If the thermal cut-off has failed,
replace the thermal cut-off and high limit
thermostat. In addition, check for failed
heater element, or blocked or improper
exhaust system.
Thermal Fuse Test
A thermal fuse is used on this model. The
thermal fuse is wired in series with the
dryer drive motor. If the thermal fuse
opens, power is shut off to the motor.
1.
Unplug dryer or disconnect power.
2.
Check continuity of thermal fuse.
3.
Once the thermal fuse has opened, it
must be replaced. Check for failed
thermistor, shorted heat element, or
other causes of failure. Replace failed
parts. See Thermal Components
illustration above.
