! WARNING

ELECTRICAL SHOCK HAZARD

Disconnect the unit from household electric supply before servicing.

Failure to do so could result in serious injury or death.

! CAUTION

ELECTROST A TIC DISCHARGE (ESD) SENSITIVE ELECTRONICS

Do not open the package containing the service replacement control assembly unitl it is time to

install it. ESD problems are present everywhere. ESD may damage or weaken the electronic

control assembly. The new control assembly may appear to work well after repair is finished,

but failure may occur at a later date due to ESD stress.

Use an anti-static wrist strap.

Connect wrist strap to green ground connection point or

unpainted metal in the appliance.

-OR-

Touch your finger repeatedly

to a green ground connection point

or unpainted metal in the appliance.

Before moving the part from its package,

touch the anit-static bag to a green ground connection

point or unpainted metal in the appliance.

Avoid touching electronic parts or terminal contacts;

handle electronic control assembly by edges only.

When repackaging a failed electronic control assembly in the anit-static bag,

observe above precautions.

INSTALLATION CONSIDERATIONS

The most common cause of electronic control failure are the result of issues related to proper installation. Before servicing the appliance, perform the following checks:

· Is the power cord firmly plugged into a live circuit with proper voltage?

· Has a household fuse blown or circuit breaker tripped? Is the circuit on a time delay fuse?

· Is the washer or dryer in Lockout? Push and hold LOCKOUT select pad under OPTIONS for 5 seconds to release.

· Are both hot and cold water faucets open and water supply hoses unobstructed?

· Check all connections before replacing components. Broken or loose wires and defective termi nals can cause the same failure symptoms as a defective component.

1. Connectors: Look at the top of the connector for broken or loose wires. Check for wires not

pressed into the connector far enough to engage metal barbs.

(Figure 2)

2. Voltage: All voltage checks must be made with all connectors ATTACHED to the board(s).

3. Resistance: All resistance checks must be made with wiring harness or connectors

DISCONNECTED.

If the appliance appears to be properly installed and a problem still exists, further diagnosis is required.
