FOR SERVICE TECHNICIAN'S USE ONLY 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. Power Cord Plug N Neu L1 CCU P9 L1 1 Wire Harness Power Cord P/N XXXXXX Rev X XXXX-XXX MADE IN COO Date Code YDDD-xx 5 N Neu COM 1 P8 Figure 4b - Plug-to-terminal connections for electric dryer. 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. 9. Plug in dryer or reconnect power. 10. Perform steps under "Install Diagnostics", page 7, 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. Figure 5 - Power cord-to-wire harness connection for gas dryer. 4. Access the machine electronics without disconnecting any wiring to the CCU (See Dryer Disassembly Instructions, page 24). 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 6 shows the position of the neutral terminal (N) on the power cord plug. Also see figure 2, page 11. 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.

In a similar way, check for continuity between the L1 terminal of the plug and P9-2 (black wire) on the CCU. 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. DO NOT REMOVE OR DESTROY PAGE 13
