DIAGNOSTIC GUIDE

Before servicing, check the following:

• Make sure there is power at the wall outlet.
• Has a household fuse blown or is the circuit breaker tripped? Was a regular fuse used? Inform the customer that a time-delay fuse is required.
• Is the dryer vent properly installed and clear of lint or obstructions?
• All tests/checks should be made with a VOM (volt-ohm-milliammeter) or DVM (digital-voltmeter) having a sensitivity of 20,000 Ω per volt DC or greater.
• Resistance checks must be made with the dryer unplugged or power disconnected.
• IMPORTANT: Avoid using large diameter probes when checking harness connectors as the probes may damage the connectors upon insertion.
• Check all harnesses and connections before replacing components. Look for connectors not fully seated, broken or loose wires and terminals, pin insertion, or wires not pressed into connectors far enough to engage metal barbs.
• A potential cause of a control not functioning is corrosion or contamination on connections. Use an ohmmeter to check for continuity across suspected connections.

ACTIVATING SERVICE DIAGNOSTIC MODE

1. Be sure the dryer is in standby mode (plugged in with all indicators off).
2. Select any three (3) buttons (except POWER) and follow the steps below, using the same buttons (remember the buttons and the order that the buttons were pressed):
   Within 8 seconds,
   • Press and Release the 1st selected button,
   • Press and Release the 2nd selected button,
   • Press and Release the 3rd selected button;
   • Repeat this 3-button sequence 2 more times.
3. If this test mode has been entered successfully, all indicators on the console will be illuminated for 5 seconds with “888” showing in the three-digit display and a tone will sound. If there are no saved fault codes, all indicators on the console will momentarily turn off, and then only the seven-segment display will come back on and display “888”.
   NOTE: The Service Diagnostic mode will time out after 10 minutes of user inactivity, or shut down if AC power is removed from the dryer.

SERVICE TEST MODE

NOTE: The Service Diagnostic mode must be activated before entering Service Test Mode; see the procedure on page 5.

NOTE: If, at any point, the user presses the POWER button or opens the door during Service Test Mode, the dryer exits to standby mode.

NOTE: The door must be closed to perform the test. The dryer must be cool before the test runs correctly.

Active Fault Code Display in Service Test Mode

If the display begins flashing while in Service Test Mode, it is displaying an active fault code. Active fault codes are codes that are currently detected. Only one active fault code can be displayed at a time.

Entry Procedure

To enter Service Test Mode, press and release the 2nd button used to activate the Service Diagnostic mode. All LEDs (except for POWER) turn off, “888” is displayed for 2 seconds, and the START button begins to flash.

TROUBLESHOOTING GUIDE

TROUBLESHOOTING TESTS

IMPORTANT: The following procedures may require the use of needle probes to measure voltage. Failure to use needle probes will damage the connectors.

TEST #1: ACU Power Check

This test is used to determine if power is present in the machine control electronics. This test assumes that proper voltage is present at the outlet.

1. Unplug the dryer or disconnect the power.
2. Check for appropriate line voltages at the outlet: 240VAC (electric 2-phase), 208VAC (electric 3-phase), or 120VAC (gas).
   • If line voltage is present, go to step 3.
   • If line voltage is not present, check for a tripped circuit breaker or blown household fuse. If the CB (circuit breaker) is not tripped, have the customer check with a qualified electrician.
3. Remove the console to access the machine electronics.
4. ACU VAC – With voltmeter set to AC, connect black probe to ACU P8-3 (N) and red probe to P9-2 (L1). (See Figure 2.) Plug in the dryer or reconnect the power.
   • If 120VAC is present, unplug the dryer or disconnect the power and go to step 5.
   • If 120VAC is not present, unplug the dryer or disconnect the power and perform TEST #2: Supply Connections, page 13.
5. ACU +5VDC – With the voltmeter set to DC, unplug connector P2 from the ACU and connect the black probe to ACU P2-3 (ground) and the red probe to P2-1 (+5V DC). Plug in the dryer or reconnect the power.
   • If +5VDC is present, unplug the dryer or disconnect the power and go to step 8.
   • If +5VDC is not present, go to step 6.

TEST #2: Supply Connections

This test assumes that proper voltage is present at the outlet, and for U.S. installations, a visual inspection indicates that the power cord is securely fastened to the terminal block (electric dryer) or wire harness connection (gas dryer).

ELECTRIC DRYER (U.S. Installations):

1. Unplug the dryer or disconnect the power.
2. Remove the cover plate from the top right corner of the back of the dryer. See Figure 3.
3. With an ohmmeter, check for continuity between the neutral (N) terminal of the plug and the center contact on the terminal block. See Figure 4a.
   1. If there is no continuity, replace the power cord and test the dryer.
   2. If there is continuity, go to step 4.
4. In a similar way, check which terminal of the plug is connected to the left-most contact on the terminal block and make a note of it. This will be L1 (black wire) in the wiring diagram. See Figure 4a.
   • When this is found, go to step 5.
   • If neither of the plug terminals has continuity with the left-most contact of the terminal block, replace the power cord and retest the dryer.
5. Access the machine electronics without disconnecting any wiring to the ACU.
6. With an ohmmeter, check for continuity between the L1 terminal of the plug (found in step 4) and P9-2 (black wire) on the ACU.
   • If there is continuity, go to step 7.
   • If there is no continuity, check that the wires to the terminal block are mechanically secure. If so, replace the main wire harness and test the dryer.

ELECTRIC DRYER (Canadian Installations):

1. Unplug the dryer or disconnect the power.
2. Remove the cover plate from the top right corner of the back of the dryer. See Figure 3.
3. Access the machine electronics without disconnecting any wiring to the ACU.
4. With an ohmmeter, check the continuity from the 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; the 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 the dryer or reconnect the power.
10. Perform steps under “Service Test Mode”, page 6, to verify repair.

TEST #3: Motor Circuit

This test will check the wiring to the motor and the motor itself. The following items are part of this motor system:

Part of Motor System	Electric Dryer	Gas Dryer
Drum belt
Door switch
Harness/connection
Thermal fuse		no
Drive motor
Belt switch
Motor capacitors
Centrifugal switch
Machine control electronics

NOTE: Refer to the strip circuit on page 24 to diagnose the drive motor.

1. Unplug the dryer or disconnect the power.
2. Remove the console to access the machine electronics.
3. Check for loose, worn, or damaged drum belts—repair as necessary.
4. Door Switch problems can be uncovered by following the procedure under TEST #7: Door Switch, page 22; however, if this is not done, the following can be performed without applying power to the dryer. Connect an ohmmeter across ACU P8-3 (neutral, white wire) and P8-4 (door, tan wire).
   • With the door properly closed, the ohmmeter should indicate a closed circuit (0–2 Ω).
   • If not, check the harnesses and connections between the ACU and the door switch. If good, replace the door switch assembly.
5. Motor Circuit Check – Access the ACU and measure the resistance across P8-4 and P9-1.
   • If the resistance across P8-4 and P9-1 is in the range of 1 to 6 Ω, the motor circuit is acceptable. Replace the ACU.
   • Otherwise, continue to step 6.
6. Check the wiring and components in the path between these measurement points by referring to the appropriate wiring diagram (gas or electric) on pages 25 or 26. NOTE: To access motor system components, slide the top back and remove the front panel.

TEST #5: Moisture Sensor

This test is performed when an automatic cycle stops too soon or runs much longer than expected.

NOTE: The dryer will shut down automatically after 2½ hours. The following items are part of this system:

Part of Moisture System	Electric Dryer	Gas Dryer
Harness/connection
Metal sensor strips
Machine control electronics

NOTE: Refer to the strip circuit on page 24 to diagnose the moisture sensor.

NOTE: Overdrying may be caused by a short circuit in the sensor system.

1. Unplug the dryer or disconnect the power.
2. Remove the console to access the machine electronics.
3. Access the moisture sensor wires by sliding the top panel back and removing the front panel. Disconnect the 3-wire moisture sensor connector located below the door opening between the front panel and bulkhead.
4. Access the ACU and remove connector P13 from the circuit board. Check the wire harness for continuity between P13 and the moisture sensor connector.
   1. If there is continuity, go to step 5.
   2. If there is no continuity, replace the main harness.
5. Measure the resistance across the outermost contacts of the connector that includes the two MOVs.
   • If a small resistance is measured, clean the two metal moisture strips inside the drum. If a small resistance is measured after cleaning, replace the sensor harness.
   • If a small resistance is not measured, go to step 6.
6. Measure the resistance across each of the outermost contacts and the center terminal (ground connection).
   • If a resistance less than infinity is measured, replace the sensor harness.
7. If the moisture sensor diagnostic test passes, check the outlet thermistor: TEST #4a, page 18.
   • If the problem persists after replacing the moisture sensor and thermistor, consider adjusting the dryness level (see TEST #5a: Adjusting Customer-Focused Dryness Level).
8. If the preceding steps did not correct the problem, replace the ACU.

TEST #9: Water Valve (on some models)

Activate Service Test Mode (see page 6). Skip to Step 8 in the Service Test Mode Chart (see page 8). Verify that water is being sprayed into the drum. See Figure 12.

NOTE: Refer to the strip circuit on page 24 to diagnose the water valve. If water leaks from the dryer/too much water is sprayed into the drum:

1. Inside the drum, unscrew the water nozzle.
2. Inspect the nozzle opening for residue buildup; clean and replace it.

If no water is sprayed in the drum:

1. Verify that the water is connected and turned on.
2. Unplug the dryer or disconnect the power.
3. Remove the console to access the machine electronics.
4. Verify that the red wire coming from the water valve is connected to the ACU, P8-1. Refer to wiring diagrams on pages 25 and 26.
5. Check Water Valve & Harness—using an ohmmeter, measure the resistance between the ACU P8-1 (red wire) and P9-2 (black wire).
   • If the resistance is 1300 Ω (±5%), go to step 6; if not, replace the water valve.
   • If an open circuit is detected, go to step 7.
6. Inside the drum, unscrew and replace the water nozzle using a 7/16″ wrench or socket. Retest the water valve.
   • If water does not dispense, go to step 7.
7. Access the water valve by removing the back panel.
   • Check that the hose and wires are connected to the water valve assembly (see Figure 12).
   • Check that the water valve assembly hose is connected to the nozzle.
8. If everything is connected and the water still does not dispense:
   • Unplug the dryer or disconnect the power.
   • Replace the valve assembly and retest.
9. If the preceding steps did not correct the problem, replace the ACU.
