FOR SERVICE TECHNICIAN ONLY - DO NOT REMOVE OR DESTROY
6. In a similar way, check the continuity between
the L1 terminal of the plug and P9-2 (black wire)
on the control board.
If there is continuity, go to step 8.
If there is no continuity, check the continuity of
the power cord in a similar way to that illustrated
in figure 5, but for power cord's L1 wire.
If an open circuit is found, replace the power
cord. Otherwise, replace the main harness.
7. Visually check that the P2 connector is inserted
all the way into the machine control electronics.
8. Visually check that the console electronics
and housing assembly is properly inserted into
the front console.
9. If both visual checks pass, replace the console
electronics and housing assembly.
10. Plug in dryer or reconnect power.
11. Perform steps under DIAGNOSTIC: Console
Buttons and Indicators, page 2, to verify repair.
12. If indicators still do not light, perform TEST #2.
TEST #2 Machine Control Power Check
This test is used to determine if power is present
at the machine control electronics. This test
assumes that TEST #1 has been completed.
NOTE: The drum light is controlled by the
machine control on all models.
1. Plug in dryer or reconnect power.
2. Open the door.
If the drum light illuminates, then power is
present at the machine control. Go to step 3.
If the drum light fails to illuminate, the problem
may be as simple as a bad bulb. Replace bulb
with a working bulb. If drum light still fails to
illuminate, continue with step 3.
3. Unplug dryer or disconnect power.
4. Replace the machine control electronics.
5. Plug in dryer or reconnect power.
6. Perform steps under DIAGNOSTIC: Console
Buttons and Indicators, page 2, to verify repair.
TEST #3 Motor Circuit
This test will check the wiring to the motor and
the motor itself.
1. Unplug dryer or disconnect power.
2. Access the machine control electronics and
measure the resistance across P8-4 and P9-1.
See Accessing & Removing the Electronic
Assemblies, page 21.
If resistance across P8-4 and P9-1 is in the range
of 1 to 6 , replace the machine control electronics.
Otherwise, go to step 3.
3. Check the wiring and components in the path
between these measurement points by referring
to the appropriate wiring diagram (gas or electric),
pages 25–28.
ELECTRIC DRYER ONLY: Check the thermal
fuse. See TEST #4b, page 17.
ALL DRYERS: Continue with step 4 below to test
the remaining components in the motor circuit.
4. Check the belt switch and drive motor. Access
the belt switch and drive motor by removing the
back panel. Slowly remove the drum belt from the
spring-loaded belt switch pulley, gently letting the
belt switch pulley down. See figure 6.
