CYCLE PHASE LABELS

Sensing Displays during Sensor cycles to indicate that the moisture sensor on the dryer is operating. It will not be displayed during Timed/Quick Dry cycles or options such as Wrinkle Shield™ option.

Drying Dryer is in the main dry phase of the automatic cycle. Steaming Steam option selected and Steam phase running.

Cool Down The dryer has finished drying with heat and is now tumbling the load without heat to cool it down.

Static Reduce Reduce Static phase is running.

End Display message will show “Drying is complete” and will timeout after 5 minutes. This will indicate that the selected cycle has ended and the load may be removed from the dryer. If Wrinkle Shield™ option has been selected, the dryer may continue to tumble the load, even if “End” is displayed.

Check Vent The Check Vent alert is a feature available for Automatic cycles only. This alert will show the status of airflow through the dryer and the dryer vent system for the dryer’s life. During the sensing phase at the beginning of the cycle if it detects a blocked vent or low pressure it will display “Check vent. Clean lint screen or vent for better performance.”

REMEMBER: The dryer will continue to operate even when check vent notification is displayed, but poor airflow can impact dry times and overall performance. Display message can be cleared by pressing any key with the exception of Power which will cancel the cycle.

USING YOUR DRYER

If you accidentally select wrong language during digital un-boxing and/or you want to get back to Factory settings then perform Factory Reset.

FACTORY RESET Press/hold both TEMP and Wrinkle Shield™ keys until display count-down has completed. Unit will power back on with “Select Language” display message.

*NOTE: See “Cycle Guide” for more information about cycles, settings, and options. Not all cycles, settings, and options are available with all models. Read all your Manuals for more information on your unit.

CYCLE GUIDE

Your dryer has a unique user interface to help you select the best cycle you need for your load. The “What to Dry” “How to Dry” layout guides you to the optimal cycle in two easy steps:

1. First determine what items are in the load that you are trying to dry. Use that to guide your “What to Dry” selection.
2. Then determine how you want the dryer to dry them by selecting the appropriate “How to Dry” selection. Modifiers are preset for the items being dried, but can be changed if desired.

To get the most energy savings and enhanced fabric care from your dryer, use the Automatic cycles. These cycles measure the drying air temperature and moisture levels to turn the dryer off once the load reaches the selected dryness level. Dryer performance and results may vary with service voltage less than rated voltage (Electric, 240 V; Gas, 120 V).

* Extended high-heat drying cycle intended to help sanitize items such as sheets and towels. This cycle is not recommended for all fabrics. For best results, this cycle should be run to completion to ensure sanitization and do not interrupt cycle.

TROUBLESHOOTING GUIDE

NOTE: Always check for Faults and Error Codes first. Some tests will require accessing components. See Figure 23 for Component Locations. For detailed troubleshooting procedures, refer to “Troubleshooting Tests”

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: Main Control (ACU)

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

1. Verify that the green LED on the ACU is lit when the dryer is turned on.
   NOTE: It is important to verify that the system is not in “Low Power” mode. If the HMI is working correctly, it will “wake up” the system after powering up and pressing Power. To verify, unplug dryer or disconnect power for 60 seconds. Plug in dryer or reconnect power. Press POWER. If the ACU comes up (i.e., the green LED in the center of the ACU flashes and then stays lit after bootup is complete) but the HMI does not, there may be a problem with the HMI.
2. Unplug dryer or disconnect power.
3. Check for appropriate line voltages at the outlet: 240 VAC (electric 2-phase), 208 VAC (electric 3-phase), or 120 VAC (gas).
   • If line voltage is present, go to step 4.
   • If line voltage is not present, check for tripped circuit breaker or blown household fuse.
   • If CB (circuit breaker) is not tripped, have customer check with qualified electrician.
4. Remove top panel to access the machine electronics
5. ACU VAC – With voltmeter set to AC, connect black probe to ACU J8-3 (N) and red probe to J9-2 (L1) (see Figure 2).
   • If 120 VAC is present, unplug dryer or disconnect power and go to step 6.
   • If 120 VAC is not present, unplug dryer or disconnect power and perform Test #2: Supply Connections.
6. ACU +5 VDC – With voltmeter set to DC, unplug connector J2 from the ACU and connect black probe to ACU J2-4 (ground) and red probe to J2-2 (+5 VDC). Plug in dryer or reconnect power.
   • If +5 VDC is present, unplug dryer or disconnect power and go to step 9.
   • If +5 VDC is not present, go to step 7.
7. Unplug dryer or disconnect power. Unplug J14 from the ACU. Plug in dryer or reconnect power and repeat step 6.
   • If +5 VDC returns, one of the thermistors has shorted. To diagnose thermistors, see Test #4a: Thermistors.
   • If +5 VDC is not present, go to step 8.
8. Unplug dryer or disconnect power. Reconnect J14 to the ACU and unplug J2 from the ACU. Plug in dryer or reconnect power and repeat step 6. Perform voltage check inside header J2 on ACU, between pins 2 & 4—DO NOT SHORT PINS TOGETHER.
   • If +5 VDC is still missing, unplug dryer or disconnect power and replace the ACU.
   • If +5 VDC returns, unplug dryer or disconnect power and check harnesses and connections between the ACU and HMI. If acceptable, replace the HMI.
9. ACU +12.7 VDC – with voltmeter set to DC, connect black probe to ACU J2-4 (ground) and red probe to J2-1 (+12.7 VDC).
   • If +12.7 VDC is present, go to step 11.
   • If +12.7 VDC is not present, go to step 10.
10. Unplug dryer or disconnect power. Unplug connector J2 from the ACU. Perform voltage check inside header J2 on ACU, between pins 1 & 4—DO NOT SHORT PINS TOGETHER.
    • If +12.7 VDC is still missing, unplug dryer or disconnect power and replace the ACU.
    • If +12.7 VDC returns, unplug dryer or disconnect power and check harnesses and connections between the ACU and HMI. If acceptable, replace the HMI.
11. Unplug dryer or disconnect power.
12. Reassemble all parts and panels.

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).

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. With an ohmmeter, check for continuity between the neutral (N) terminal of the plug and the center contact on the terminal block. See figure 4. ➢ If there is no continuity, replace the power cord and test the dryer. ➢ 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 4.
   • When this is found, go to step 5.
   • If neither of the plug terminals have continuity with the left-most contact of the terminal block, replace the power cord and retest 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 J9-2 (black wire) on the ACU.
   • If there is continuity, go to step 7.
   • If there is no continuity, check that wires to the terminal block are mechanically secure. If so, replace the main wire harness and test the dryer.
7. Check for continuity between the neutral (N) terminal of the plug and J8-3 (white wire) on the ACU.
   • If there is continuity, go to step 8.
   • If there is no continuity, and the mechanical connections of the wire are secure, replace the main wire harness.
8. Visually check that ALL connectors are fully inserted into the ACU.
9. Visually check that ALL connectors are fully inserted into the HMI.
10. Reassemble all parts and panels.
11. Plug in dryer or reconnect power.
12. Perform steps under “Service Test Mode”, 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:

NOTE: Refer to strip circuit to diagnose drive motor.

1. Unplug dryer or disconnect power.
2. Remove console to access the machine electronics. Loosen top and slide back to view drum belt.
3. Check for loose, worn, or damaged drum belt—repair as necessary.
4. Door Switch problems can be uncovered by following procedure under Test #7: Door Switch; however, if this was not done, the following can be performed without applying power to the dryer. Connect an ohmmeter across ACU J8-3 (neutral, white wire) and J8-4 (door, tan wire).
   • With the door properly closed, the ohmmeter should indicate a closed circuit (0–2 Ω).
   • If not, check harnesses and connections between ACU and door switch. If good, replace the door switch assembly.
5. Motor Circuit Check - Access the ACU and measure the resistance across J8-4 and J9-1.
   • If resistance across J8-4 and J9-1 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). NOTE: To access motor system components, slide the top back and remove the front panel.
   ALL DRYERS: Continue with step 7 below to test the remaining components in the motor circuit.
7. Check the drive motor. Slowly remove the drum belt from the springloaded pulley, gently letting the pulley down. See figure 8.
   
8. Remove the white connector from the drive motor switch. See figure 9.
   
9. Remove the bare copper wire terminal from pin 5 of black drive motor switch. See figure 10.
   
10. Using figure 10 and the strip circuit, check for the resistance values of the motor’s Main and Start winding coils as shown in the following table.
    NOTE: Main and Start winding coils must be checked at the motor.
    
    
    • If the resistance at the motor is correct, there is an open circuit between the motor and ACU. For gas models, check for a belt switch problem; see step 11. For electric models, check and repair the main wiring harness.
    • If the Main or Start winding resistance is much greater or less than the values listed in the table above, replace the motor.
11. On gas dryer only, check the belt switch by unplugging the connector and measuring the resistance between pins 1 and 3 of the belt switch connector while pushing up the pulley (see figure 10).
    • If the resistance reading goes from open to a few ohms as pulley arm closes the switch, belt switch is good. If not, replace the belt switch.
    • If belt switch is good and there is still an open circuit, check and repair the main wiring harness.
12. Reassemble all parts and panels.
13. Plug in dryer or reconnect power.
14. Perform steps under “Service Test Mode”, to verify repair.

• Heat will not shut off

This test checks the components making up the heating circuit. The following items are part of this system:

NOTE: On the gas dryer, the inlet thermistor is located at the drum inlet vent. Refer to strip circuit to diagnose heater system.

Dryer does not heat:

Locate the components using figures 14 and 15. To access heater system components, remove the console, top panel, and front panel.

• If L1 is present, the heater relay is receiving L1 line voltage.
• If L2 is present, the heater relay is receiving L2 line voltage, confirming that the centrifugal switch, heater, high limit thermostat, and thermal cut-off are functional.

1. Unplug dryer or disconnect power.
2. Remove the front panel to access thermal components.
3. Using an ohmmeter and referring to the strip circuit or wiring diagram, measure the resistance from the red wire terminal at the thermal cut-off to the red wire terminal at the heater.
   • If the resistance is about 10 Ω, go to step 5.
   • If an open circuit is detected, go to step 4.
     
4. Visually check the wire connections to the thermal cut-off, high limit thermostat, and heater. If the connections look good, check for continuity across each of these components. Refer to strip circuit.
   • Replace the heater if it is electrically open.
   • Replace both the thermal cut-off and the high limit thermostat if either the thermal cut-off or the high limit thermostat is electrically open.
5. If no open circuit is detected, remove the J14 connector from the ACU and measure the outlet thermistor resistance between J14-3 and J14-6 at the connector. Refer to “Outlet Thermistor Resistance” table for temperatures and their associated values.
   • If the resistance corresponds to the temperature, the outlet thermistor is good. Go to step 6.
   • If the thermistor resistance does not agree with the table, replace the outlet thermistor.
6. If the preceding steps did not correct the problem and L1 and L2 were both detected, replace the ACU. If L2 was not detected, suspect the centrifugal switch before replacing the ACU.
7. Reassemble all parts and panels.
8. Plug in dryer or reconnect power.
9. Perform steps under “Service Test Mode”, to verify repair.

NOTE: Begin with an empty dryer and a clean lint screen.

1. Unplug dryer or disconnect power.
2. Remove console to access the machine electronics.
3. Remove connector J14 from the ACU and measure the resistance between J14-3 and J14-6 at the connector. The following table gives temperatures and their associated resistance values. NOTE: All thermistor resistance measurements must be made while dryer is unplugged and connector removed from ACU.
   
   
   • If the resistance is OK, the outlet thermistor is good. Proceed to step 4.
   • If the thermistor resistance does not agree with the table, replace the outlet thermistor.
4. Check J14-3 and J14-6 to dryer cabinet ground. If either pin indicates continuity to ground (short), replace wiring harness; otherwise, proceed to step 5. 5. If the preceding steps did not correct the problem, replace the ACU.

Temperature Levels Incorrect – If no error code is displayed and the connections to the thermistor are good, check the exhaust temperature value at any or all of the temperature levels in question, using the Timed Dry cycle.

IMPORTANT: Be sure EcoBoost or Energy Saver (if available) is turned OFF before testing.

1. Remove load from dryer and disconnect external vent.
2. Plug in dryer or reconnect power.
3. Run a TIMED DRY cycle (Mixed + Timed Dry on Whirlpool models) of at least 2 minutes in duration and select a temperature setting using heat
4. Using a calibrated temperature probe, take a temperature measurement in the center of the exhaust outlet. The correct exhaust temperatures are as follows:
   
   • If the temperature is not reached within ~7 minutes, check voltage level and vent blockage, and then retest.
   • If the temperature probe does not agree with temperature setting, replace the outlet thermistor.
   • If the temperature probe confirms the temperature setting, retest at a different temperature setting.
5. f the preceding steps did not correct the problem, replace the ACU.

Inlet Thermistor

NOTE: On the electric dryer, the inlet thermistor is part of the high thermostat assembly (see figure 11). On the gas dryer, the inlet thermistor is located at the drum inlet duct (see figure 23).
