COMPONENT TESTING

Whirlpool & Maytag 9.2 Cu. Ft. Steam Dryer

3-17

For Service Technician Use Only

TEST #5: Moisture Sensor

This test is performed when an automatic cycle stops too

soon, or runs much longer than expected.

NOTE:

Dryer will shut down automatically after 2½ hours.

The following items are part of this system:

Part of Moisture System

Electric Dryer

Gas

Harness/connection

Metal sensor strips

Machine control electronics

NOTE:

Refer to strip circuit below to diagnose moisture sensor.

NOTE:

Over-drying may be caused by a short circuit in the

sensor system.

1.  Unplug dryer or disconnect power.
2.  Remove 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 J13 from the circuit

board. Check the wire harness for continuity between J13

and the moisture sensor connector.

If there is continuity, go to step 5.

If there is no continuity, replace the main harness.with

step 3.

5. Measure the resistance across the outermost contacts of

the connector that includes the two MOVs.

TEST #5: Moisture Sensor

This test is performed when an automatic

cycle stops too soon, or runs much longer

than expected.

NOTE:

Dryer will shut down automatically

after 4 hours and 10 minutes.
The following items are part of this system:

NOTE:

Refer to strip circuit on page 20

to diagnose moisture sensor.

Activate the Loads Test mode. See

procedures on page 4.

Open the door. Using a wet cloth or one

finger, jointly touch both sensor strips.

If a repeating beep tone is heard and an

alphanumeric number is displayed on the

console, the moisture sensor passes the

test. Go to step 9.

If a beep tone is not heard, or a repeating

beep tone is heard before touching both

moisture strips, continue with step 3.

NOTE:

Overdrying may be caused by a short

circuit in the sensor system.

Unplug dryer or disconnect power.

Remove top panel to access the machine

electronics.

Access the moisture sensor wires

by removing the console and front panel.

Disconnect the 3-wire moisture sensor

connector located below the door opening

between the front panel and bulkhead.

Access the CCU and remove connector

P13

from the circuit board. Check the wire

harness for continuity between P13 and the

moisture sensor connector.

If there is continuity, go to step 7.

If there is no continuity, replace the main

harness.

Part of Moisture System

Electric

Dryer

Harness/connection

Metal sensor strips

Machine control electronics

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 sensor harness.

If a small resistance is not measured,

go to step 8.

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.

If the moisture sensor diagnostic test passes,

check the outlet thermistor: TEST #4a, page 15.

If the problem persists after replacing the

moisture sensor and thermistor, consider

adjusting the dryness level (see TEST #5a:

Adjusting Customer-Focused Dryness Level).

10.

If the preceding steps did not correct the

problem, replace the CCU.

TEST #5a: Adjusting Customer-

Focused Dryness Level

NOTE:

If the customer complains about the

clothes being less dry or more dry than desired

and the moisture sensor passes TEST #5:

Moisture Sensor, step 2, the total dry time can

be lengthened or shortened by changing the

Customer-Focused Dryness Level from “

”

(standard auto cycle) to a “

” (15% more drying

time), “

” (30% more drying time), “

” (15%

less drying time), or “

” (30% less drying time)

auto cycle.

In standby mode (dryer plugged in but not

powered up), press and hold the

DRYNESS

LEVEL

button for approximately 3 seconds.

The dryer will beep and “

” is displayed

followed by the current dryness setting on the

7-segment display. The factory default value

is “

”.

If a small resistance is measured, clean the two metal

moisture strips inside the drum. If a small resistance is

measured after cleaning, replace 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).
