FOR SERVICE TECHNICIAN'S USE ONLY
Heat will not shut off:
1. Unplug dryer or disconnect power.
2. Remove rear panel to access the machine
electronics and thermal components.
3. Check heater coil for a short to ground
(usually inside the heater box). Repair or
replace if necessary.
4. Plug in dryer or reconnect power.
5. Run an "AIR" only timed dry cycle (no
heat). With a voltmeter set to AC, connect
voltmeter to timer terminals C and A and
measure the voltage across terminals C
and A.
 If voltage is present (~240VAC for 240V
electric models, ~120VAC for 120V
electric models), heat system is working
normally.
 If little or no voltage is present, the heater
is activated. Unplug dryer or disconnect
power and replace the timer.
6. Unplug dryer or disconnect power.
7. Reassemble all parts and panels.
8. Plug in dryer or reconnect power.
TEST #3a: Thermal Fuse
1. Unplug dryer or disconnect power.
2. Access the thermal fuse by removing
the rear panel.
3. Using an ohmmeter, check the continuity
across the thermal fuse.
 If the ohmmeter indicates an open circuit,
replace the thermal fuse.
4. Reassemble all parts and panels.
5. Plug in dryer or reconnect power.
DO NOT REMOVE OR DESTROY
TEST #4: Moisture Sensor
(120V models only)
This test is performed when an automatic
cycle stops too soon, or runs much longer
than expected.
NOTE: Overdrying may be caused by
a short circuit in the sensor system.
1. Unplug dryer or disconnect power.
2. Access the sensor terminal by removing
the back panel. Disconnect the moisture
sensor connector.
3. Access the C board moisture sensor
connection by removing the C board.
Check continuity between the C board
harness moisture sensor connection
(pin 3) and the moisture sensor connector.
 If there is continuity, go to step 4.
 If there is no continuity, replace the main
harness.
4. Measure the resistance across the
outermost contacts of the connector.
 If a small resistance is measured, clean the
two metal moisture strips inside the drum.
If a small resistance is measured after
cleaning, replace sensor harness.
 If a small resistance is not measured,
replace the C board.
TEST #5: Door Switch
1. Unplug dryer or disconnect power.
2. Check wire connections at the door switch
and Start switch.
3. With the door closed, check continuity
between the two outer pins on the door
switch.
 If there is no continuity, replace the
door switch.
4. Reassemble all parts and panels.
5. Plug in dryer or reconnect power.
