COMPONENT TESTING

Whirlpool & Maytag 9.2 Cu. Ft. Steam Dryer

3-21

For Service Technician Use Only

DANGER

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.

TEST #8: Drum LED

NOTE:

Refer to the strip circuit at right (Figure 2) to diagnose

the drum LED.
This test is performed if the drum LED does not light.

1.  Unplug dryer or disconnect power.
2.  Remove the console to access ACU and user interface (UI).
3.  Verify that the drum LED connector

is securely

connected to the ACU (see Figure 1).

4. Check harness and inline connections between the drum

LED and ACU.

If the harness and connections are good, go to step 5.

If not, repair or replace as needed.

5. Unplug the drum LED connector

from the ACU.

6. With a multimeter set to milliamps, connect multimeter to

ACU connector

, pins 1 and 3. Plug in dryer or reconnect

power. Open the door. Measure the current across ACU

connector

, pins 1 and 3. If the drum LED driver is

working properly, there should be a measurement of 150

mA.

If the current is present, unplug dryer or disconnect

power and replace the drum LED.

If the current is not present, unplug dryer or disconnect

power and replace the ACU.

7. Reassemble all parts and panels.
