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

CCU. 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 CCU;

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 CCU.

7. Visually check that ALL connectors are

fully inserted into the UI.

8. Reassemble all parts and panels.

10. Perform steps under “Install Diagnostics”,

page 5, to verify repair.

GAS DRYER (U.S. and Canadian Installations):

1. Unplug dryer or disconnect power.

2. Remove the cover plate from the back

of the dryer. See Figure 5.

3. Check that the power cord is ﬁrmly

connected to the dryer’s wire harness.

See Figure 6.

4. Access the machine electronics without

disconnecting any wiring to the CCU.

5. With an ohmmeter, check for continuity

between the neutral (N) terminal of the plug and

P8-3 (white wire) on the CCU. The left-hand

side of Figure 7 shows the position of the neutral

terminal (N) on the power cord plug. Also see
