4. With an ohmmeter, check thecontinuity from
L1 and N plug terminalsof the powercord to the
terminals for L1 and N on the machine control
electronics.See figure 3b.
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 machine control board;
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 the power supply connector
is inserted all the way into the power supply.
7. Visually check that the console electronics
and housing assembly is properly inserted into
the front console.
8. If both visual checks pass, replace the console
electronics and housing assembly.
9. Reinstall components and reattach any wires
that were removed.
10. Plug in dryer or reconnect power.
11. Perform steps under Manual Diagnostic
Test Mode, page 2,to verify repair.
12. If problems persist,the machine control
electronics has failed:
Unplug dryer or disconnect power.
Replace the machine control electronics.
Plug in dryer or reconnect power.
Perform steps under Manual Diagnostic
Test Mode, page 2,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 2,
page 8.
3. Check that the power cord is firmly connected
to the dryers wire harness. See figure 4.
4. Access the machine control electronics
without disconnecting any wiring to the control
board.
5. With an ohmmeter, check for continuity
between the neutral (N) terminal of the plug and
P8-3 (white wire) on the machine control board.
The left-hand side of figure 5 shows the position
of the neutral terminal (N) on the power cord plug.
If there is continuity, go to step 6.
If there is no continuity, disconnect the white
wire of the harness from the power cord at the
location illustrated in figure 4.Test the continuity
of the power cord neutral wire as illustrated in
figure 5.If an open circuit is found,replace the
power cord. Otherwise, go to step 6.
