5. With an ohmmeter, check for continuity
(0 Ω) between the neutral (N) terminal of
the plug and white wire (N) of the harness
connector. The left-hand side of the
illustration below shows the position of the
neutral terminal (N) on the power cord plug.
• If there is continuity (0 Ω), go to step 6.
• If there is no continuity, or an open circuit
(infinite Ω) is found, replace the power cord.
Otherwise, go to step 6.
6. In a similar way, check for continuity (0 Ω)
between the L1 terminal of the plug and
black wire at the harness connection.
• If there is continuity (0 Ω), go to step 8.
• If there is no continuity, check for continuity
(0 Ω) of the power cord in a similar way to
that illustrated in step 5, but for power cord's
L1 wire.
• If an open circuit (infinite Ω) is found,
replace the power cord. Otherwise, go to
step 7.
7. Visually check that the UIC transformer is
connected to the UIC at AA6 and no wires
are loose in the connector.
8. Visually check that the P2 connector is
inserted all the way into the dryer CCU
control board.
9. Visually check that all UIC connections are
tight and all wires secured into connectors.
10. If all of the visual checks pass, reinstall the
console electronics, housing assembly, and
all parts and panels before operating.
11. Plug in dryer or reconnect power.
12. Perform the Diagnostic Test to verify repair.
13. If indicators do not light, the dryer UIC
electronics have failed:
• Unplug dryer or disconnect power.
• Replace the dryer UIC.
• Reinstall all the parts and panels before
operating.
• Plug in dryer or reconnect power.
• Perform Diagnostic Test to verify repair.
14. If all steps check OK, replace the main
wire harness.
TEST #2: Motor circuit Test
This test will check the wiring to the motor and
the motor itself. The following items are part
of this motor system:
Part of Motor System
Harness / connection
Belt / belt switch
Drive motor
Centrifugal switch
Door switches
Machine control ESD info
(See page 1-1).
1. Unplug dryer or disconnect power.
2. Check for a broken belt on the dryer drum.
If belt is OK, go to step 3.
