6. Access the machine control electronics
without disconnecting any wiring to the
control board. See Accessing & Remov-
ing the Electronic Assemblies.
7. With an ohmmeter, check for continuity
between the L1 terminal of the plug (found
in step 5) and P9-2 (black wire) on the ma-
chine control board. See Figure 15.
• If there is continuity, go to step 8.
• If there is no continuity, check that wires
to the terminal block are mechanically
secure. If so, replace the main wire
harness and test the dryer.
8. Check for continuity between the neutral
(N) terminal of the plug and P8-3 (white
wire) on the machine control board.
• If there is continuity, go to step 9.
• If there is no continuity and the mechan-
ical connections of the wire are secure,
replace the main wire harness.
9. Visually check that the P5 connector is
inserted all the way into the machine
control electronics.
10. Visually check that the user interface as-
sembly is properly inserted into the front
console.
11. If both visual checks pass, replace the
user interface assembly.
12. Plug in dryer or reconnect power.
13. Perform the Console Buttons and Indica-
tors Diagnostic test to verify repair.
14. If indicators still do not light, the machine
control electronics has failed:
• Unplug dryer or disconnect power.
• Replace the machine control electron-
ics.
• Plug in dryer or reconnect power.
• Perform the Console Buttons and Indi-
cators Diagnostic test to verify repair.
TEST #2 Machine Control Power Check
This test is used to determine if power is pres-
ent at the machine control electronics.
NOTE: The drum light is controlled by the ma-
chine 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 TEST #6.
• If the drum light fails to illuminate, do
not assume the machine control elec-
tronics needs replacement. Several
conditions may cause the drum light
not to illuminate, including a bad bulb.
If the drum light does not illuminate, go
to TEST #1.
TEST #3 Drive Motor Circuit
This test will check the wiring to the motor and
the motor itself. The following items are part
of this motor system:
• Harness/connection
• Thermal fuse
• Belt/belt switch
• Drive motor
• Centrifugal switch
• Door switch
• Machine control electronics
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.
• If resistance across P8-4 and P9-1 is
in the range of 1 to 6 ohms, 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 dia-
gram and strip circuit in Section 7.
4. Check the thermal fuse. See TEST #4b.
