GENERAL INFORMATION

General Info

INTRODUCTION

The new Whirlpool and Maytag Steam Dryers represents
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.

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.

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.

What to Dry

Figure 1 - User Interface with Intuitive Touch Controls

Extra Large 9.2 cu. . Capacity Drum — Our largest dryer
opening available, the Whirlpool and Maytag dryers have an
extra large drum capacity of 9.2 cu.. The drum’s stainless
steel construcon presents a smooth surface that helps deliver
ulmate gentleness, cradling clothes as they tumble.

How to Dry

Advanced Moisture Sensing — now using up to four (4)
moisture sensors to track moisture more accurately. Two
moisture sensors in the front of the dryer, located on the lint
screen outlet grill, (see Figure 3 below) and on Maytag models,
two moisture sensors in the back of the dryer, located on the
rear bulkhead, (circled in Figure 2).

continuity across suspected connections.

SERVICE DIAGNOSTIC 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 specific troubleshooting tests.

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 “”
showing in the three-digit display and a tone
will sound. If there are no saved fault codes,
all indicators on the console will turn off,
and only the seven segment display will
remain on.

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.

DIAGNOSTICS & TROUBLESHOOTING

For Service Technician Use Only

Diagnosc Guide

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 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 (volt-

ohm-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.

n Check all harnesses and connecons before replacing

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
