TROUBLESHOOTING PROBLEM: Dryer Will Not Run Refer to Motor Strip Circuit, page 7-3 or 7-6; and Troubleshooting Guide, page 6-9. 1. Unplug dryer or disconnect power. 2. Check connector pins in P2 connector of the electronic control to verify they are making good connections. 3. Check the Push to Start (PTS) switch continuity when pressed. It should show continuity while pushed in. If not, replace the PTS switch. 4. Perform Thermal Fuse Test, page 6-6. 5. Perform Door Switch Test, page 6-5. 6. If the motor started but did not continue to run, and components checked in steps 2 through 5 were OK, replace the electronic control assembly. 7. If motor did not start and components checked in steps 2 through 5 were OK, replace the motor. PROBLEM: Dryer Will Not Heat Electric Only Refer to Heater Strip Circuit, page 7-3; and Troubleshooting Guide, page 6-9. 1. Perform Supply Connections Test, page 6-3. 2. Perform Thermal Cut-Off Test, page 6-6. 3. Perform High Limit Thermostat Test, pages 6-5 & 6-6. 4. Unplug dryer or disconnect power. 5. Check continuity of heater: • Each element should be about 20 Ω and should be open to ground, chassis, and neutral. • If either element fails these tests in step 5, replace the heat element assembly. 6. Check continuity of motor centrifugal switch: • 1M to 2M terminals should be open the off condition. Manually operating the switch should close 1M to 2M. This can be done by pushing the actuator from the off condition to the run position. See the illustrations below. • If these conditions are not true, replace the motor. Actuator in off condition. Actuator in run position. PROBLEM: Dryer Will Not Heat Gas Only Refer to Heater Strip Circuit, page 7-6; and Troubleshooting Guide, 6-9. 1. Perform Supply Connections Test, page 6-4. 2. Perform Thermal Cut-Off Test, page 6-6. 3. Perform High Limit Thermostat Test, pages 6-5 & 6-6. 4. Perform Thermal Fuse Test, page 6-6. 5. Perform Gas Valve Test, page 6-8. 6-10

TROUBLESHOOTING
PROBLEM: Dryer Will Not Run
Refer to Motor Strip Circuit, page 7-3 or 7-6;
and Troubleshooting Guide, page 6-9.
1.
Unplug dryer or disconnect power.
2.
Check connector pins in P2 connector of
the electronic control to verify they are
making good connections.
3.
Check the Push to Start (PTS) switch
continuity when pressed. It should show
continuity while pushed in. If not, replace
the PTS switch.
4.
Perform Thermal Fuse Test, page 6-6.
5.
Perform Door Switch Test, page 6-5.
6.
If the motor started but did not continue
to run, and components checked in steps
2 through 5 were OK, replace the elec-
tronic control assembly.
7.
If motor did not start and components
checked in steps 2 through 5 were OK,
replace the motor.
PROBLEM: Dryer Will Not Heat
Electric Only
Refer to Heater Strip Circuit, page 7-3; and
Troubleshooting Guide, page 6-9.
1.
Perform Supply Connections Test, page
6-3.
2.
Perform Thermal Cut-Off Test, page 6-6.
3.
Perform High Limit Thermostat Test, pages
6-5 & 6-6.
4.
Unplug dryer or disconnect power.
5.
Check continuity of heater:
Each element should be about 20 Ω
and should be open to ground, chas-
sis, and neutral.
If either element fails these tests in
step 5, replace the heat element as-
sembly.
6.
Check continuity of motor centrifugal
switch:
1M to 2M terminals should be open
the off condition. Manually operating
the switch should close 1M to 2M. This
can be done by pushing the actuator
from the off condition to the run posi-
tion. See the illustrations below.
If these conditions are not true, replace
the motor.
Actuator in off condition.
Actuator in run position.
