Remove the cover plate from the top right corner of the back of the dryer. See figure 3. 3. Check that the power cord is firmly connected to the dryer's wire harness. See figure 5. 4. Access the machine electronics without disconnecting any wiring to the ACU. 5. With an ohmmeter, check for continuity between the neutral (N) terminal of the plug and P8-3 (white wire) on the ACU.

4.
With an ohmmeter, check the continuity
from L1 and N plug terminals of the power
cord to the terminals for L1 and N on the
ACU. See figure 4b.
If continuity exists for both connections,
go to step 6.
If an open circuit is found, check the integrity
of the connections of the power cord to the
harness in the dryer; harness to the ACU;
and the integrity of the power cord itself.
5.
If it is necessary to replace the power
cord, remove the retaining clip that secures
the cord to the back panel. Disconnect the
cord from the main harness and the ground
wire from the rear panel, then pull out the
power cord.
6.
Visually check that ALL connectors are
fully inserted into the ACU.
7.
Visually check that ALL connectors are
fully inserted into the UI.
8.
Reassemble all parts and panels.
9.
Plug in dryer or reconnect power.
10.
Perform steps under “Service Test Mode”,
page 6, to verify repair.
GAS DRYER (U.S. and Canadian Installations):
1.
Unplug dryer or disconnect power.
2.
Remove the cover plate from the top right
corner of the back of the dryer. See figure 3.
3.
Check that the power cord is firmly
connected to the dryer’s wire harness.
See figure 5.
4.
Access the machine electronics without
disconnecting any wiring to the ACU.
5.
With an ohmmeter, check for continuity
between the neutral (N) terminal of the plug and
P8-3 (white wire) on the ACU. The left-hand
side of figure 6 shows the position of the neutral
terminal (N) on the power cord plug. Also see
figure 2, page 12.
If there is continuity, go to step 6.
If there is no continuity, disconnect the
white wire of the main harness from the
power cord at the location illustrated in
figure 5. Test the continuity of the power
cord neutral wire as illustrated in figure 6.
If an open circuit is found, replace the
power cord. Otherwise, go to step 6.
6.
In a similar way, check for continuity
between the L1 terminal of the plug and P9-2
(black wire) on the ACU.
If there is continuity, go to step 7.
If there is no continuity, check the continuity
of the power cord in a similar way to that
illustrated in figure 6, 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 ALL connectors are fully
inserted into the ACU.
8.
Visually check that ALL connectors are fully
inserted into the UI.
