FOR SERVICE TECHNICIAN'S USE ONLY The dryer will beep and "CF" or "F" is displayed followed by the current dryness setting on the 7-segment display. The factory default value is "1". 2. Pressing the dryness level button cycles the dryness setting between 1, 2, 3, 4, and 5 in that order, starting at the current setting. The new setting is displayed in the 7-segment display. 3. With the display showing the desired dryness setting, press the START button to save the drying mode and exit to standby mode (the START button in this mode does not start a drying cycle). The result will be stored in EEPROM of the CCU and will be retained after a power loss. NOTE: If there is no user activity for 20 seconds, or a button other than START or DRYNESS LEVEL is pressed, the dryness setting is reverted back to its previous setting. 4. Press the POWER button at any time to cancel changes and exit from this mode. TEST #6: Buttons and Indicators This test is performed when any of the following situations occurs during the "Console Buttons and Indicators Test" (see page 5). NOTE: Some models may not have cycle indicator lights and may beep only on the Normal cycle. 3 None of the indicators or display turn on 3 Some buttons do not light 3 No beep sound is heard None of the indicators or display turn on: 1. Unplug dryer or disconnect power. 2. Remove top panel to access the CCU and user interface (UI). 3. Visually check that ALL CCU connectors are inserted all the way into the CCU. 4. Visually check that ALL UI connectors are inserted all the way into the UI. 5. Visually check that the UI and housing assembly is properly inserted into the front console. 6. If all visual checks pass, perform TEST #1: CCU Power Check, page 11, to verify supply voltages.  If supply voltages are present, replace the user interface and housing assembly.  If supply voltages are not present, replace the CCU. 7. Reassemble all parts and panels. 8. Plug in dryer or reconnect power. 9. Perform the "Console Buttons and Indicators Test" (see page 5) to verify repair. Some buttons do not light: 1. Unplug dryer or disconnect power. 2. Remove top panel to access the CCU and user interface (UI). 3. Visually check that the UI and housing assembly is properly inserted into the front console. 4. If visual check passes, replace the UI and housing assembly. 5. Reassemble all parts and panels. 6. Plug in dryer or reconnect power. 7. Perform the "Console Buttons and Indicators Test" (see page 5) to verify repair. No beep sound is heard (on some models, only the Normal cycle beeps upon cycle selection): 1. On some models, verify that the "Cycle Signal" volume is turned on. Press the CYCLE SIGNAL button to adjust the volume level. 2. Unplug dryer or disconnect power. 3. Remove top panel to access the CCU and user interface (UI). 4. Visually check that ALL CCU connectors are inserted all the way into the CCU. 5. Visually check that ALL UI connectors are inserted all the way into the UI. 6. If all visual checks pass, replace the UI and housing assembly. 7. Reassemble all parts and panels. 8. Plug in dryer or reconnect power. 9. Perform the "Console Buttons and Indicators Test" (see page 5) to verify repair. TEST #7: Door Switch Activate the Loads Test mode. See procedures on page 5. Perform the steps under "Diagnostic: Door Switch/Drum LED." Functionality is verified when opening the door causes "eee" or "ee" (electric), "999" or "99" (gas) to be displayed and turns on the drum light (on some models). Closing the door should turn off the drum light (on some models). If the preceding conditions are not met: 1. Unplug dryer or disconnect power. 2. Remove top panel to access the machine electronics. 3. Check that the wires between the door switch and CCU are connected. (Refer to wiring diagrams on pages 26 and 27.)  If the connections are good, replace the wire and door switch assembly and retest. DO NOT REMOVE OR DESTROY PAGE 21
