GENERAL INFORMA INFORMATION TION

General Info INTRODUCTION The new Whirlpool and Maytag Steam Dryers represents industry-leading industry-leading innovaon with Advanced Moisture Sensing using three sensors to track moisture and temperature, adapng drying mes to end the cycle at just the right me.

Addional features include 9.2 cu. . capacity, Stainless Steel Drum, Intuive Touch Controls with Memory, Customized Fabric Care, and a Steam Refresh Cycle that releases wrinkles and reduces odors without rewashing.

NEW COMPONENTS Sleek Under Glass User Interface — the Whirlpool dryer features a new sleek under glass capacive touch user interface that asks “what’s being dried” followed by “how you want to dry.” First select a cycle from the “What to Dry” (Casuals, Jeans, Towels, Delicates, AcveWear, and Bulky Sheets) and then select the “How to Dry” (Normal, Gentle, Sanize, Quick, Timed Dry, Steam Refresh). This new and improved input will help the customer achieve the best combinaon cycle available for the type of items being dried.

DIAGNOSTICS & TROUBLESHOO TROUBLESHOOTING TING

For Service Technician Use Only Diagnosc Guide Before Before servicing, check the following: n Make sure there is power at the wall outlet. n Make sure control lock is not enabled. n Has a household fuse blown or circuit breaker breaker tripped? Was a regular fuse used? Inform customer that a me-delay fuse is required. n Is dryer vent properly installed and clear of lint or obstrucons? n All tests/checks should be made with a VOM (voltohm-milliammeter) or DVM (digital-voltmeter) having a sensivity of 20,000 Ω per volt DC or greater. n Resistance checks must be made with dryer unplugged or power disconnected. n IMPORTANT: Avoid using large diameter probes when checking harness connectors as the probes may damage the connectors upon inseron. before replacing n Check all harnesses and connecons before components. Look for connectors not fully seated, broken or loose wires and terminals, pin inseron, or wires not pressed into connectors far enough to engage metal barbs. n A potenal cause of a control not funconing is corrosion or contaminaon on connecons. Use an ohmmeter to check for connuity across suspected connecons.

Service Diagnosc Mode These tests allow service personnel to test and verify all inputs to the machine control electronics. You may want to do a quick and overall checkup of the dryer with these tests before going to specic troubleshoong tests.

Acvang Service Diagnosc Mode 1. Be sure the dryer is in standby standby mode (plugged in with all indicators o). 2. Select any three (3) buons (except (except POWER) and follow follow the steps below, using the same buons (remember the buons and the order that the buons were pressed):

Electrical Shock Hazard Only authorized technicians should perform diagnostic voltage measurements. After performing voltage measurements, disconnect power before servicing. Failure to follow these instructions can result in death or electrical shock.

Component Tesng TESTING DRYER COMPONENTS FROM THE CONTROL Before tesng any of the components, perform the following checks: • The most common cause for mis-diagnosed mis-diagno sed control failure is poor connecons. Therefore, disconnecng, inspecng and reconnecng wires will be necessary throughout test procedures. • All tests/checks should be made with a VOM or DVM having a sensivity of 20,000 ohms-per-volt DC, or greater. • Check all connecons before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors connectors far enough. • Voltage checks must be made with all connectors aached to the boards. • IMPORTANT: Resistance checks must be made with power cord unplugged or power disconnected, and with wiring harness or connectors disconnected from the control. The tesng procedures in this secon 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 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 ACU is not in “Hibernate” mode. If the user interface interface is working correctly, it will “wake up” the ACU aer powering up. To verify, unplug dryer or disconnect power for 60 seconds.

3-6 n Whirlpool & Maytag 9.2 Cu. Ft. Steam Dryer 

Plug in dryer or reconnect power. Press POWER. If the ACU comes up (i.e., the green LED in the center of the ACU ashes and then stays lit aer boot-up is complete), there may be a problem with the user interface. 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). ¾ If line voltage is present, go to step 4. ¾ 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 qualied electrician. 4. Remove console 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 1, page 3-7.) Plug in dryer or reconnect power. ¾ If 120 VAC is present, unplug dryer or disconnect power and go to step 6. ¾ If 120 VAC is not present, unplug dryer or disconnect power and perform TEST #2: Supply Connecons, page 3-8. 6. ACU +5 VDC – With voltmeter set to DC, unplug connector J2 from the ACU and connect black probe to ACU J2-3 (ground) and red probe to J2-1 (+5 VDC). Plug in dryer or reconnect power. ¾ If +5 VDC is present, go to step 9. ¾ 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. ¾ If +5 VDC returns, one of the thermistors has shorted. To diagnose thermistors, see TEST #4a, page 3-14. ¾ 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 1 & 3—DO NOT SHORT PINS TOGETHER. ¾ If +5 VDC is sll missing, unplug dryer or disconnect power and replace the ACU. ¾ If +5 VDC returns, unplug dryer or disconnect power and check harnesses and connecons between the ACU and user interface (UI). If acceptable, replace the UI. 9. Unplug dryer or disconnect power. 10. Reassemble Reassemble all parts and panels. 11. Perform steps under “Service Test Mode”, Mode”, page 2-5, to verify repair.
