IMPORTANT SAFETY NOTICE

The information in this service guide is intended for use by individuals possessing skill and experience in electrical, electronic, and mechanical appliance repair. Any attempt to repair a major appliance may result in personal injury and property damage. The manufacturer or seller cannot be responsible for the interpretation of this information, nor can it assume any liability in connection with its use.

!

WARNING !

To avoid personal injury, disconnect power before servicing this product. If electrical power is required for diagnosis or test purposes, disconnect the power immediately after performing the necessary checks.

RECONNECT ALL GROUNDING DEVICES

If grounding wires, screws, straps, clips, nuts, or washers used to complete a path to ground are removed for service, they must be returned to their original position and properly fastened.

WHAT TO DO IF YOU SMELL GAS:

■ Do not try to light a match, or cigarette, or turn on any gas or electrical appliance.

■ Do not touch any electrical switches. Do not use any phone in your building.

■ Clear the room, building or area of all occupants.

■ Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions carefully.

■ If you cannot reach your gas supplier, call the fire department.

IMPORTANT

Electrostatic Discharge (ESD)

Sensitive Electronics

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 removing the part from its package, touch the anti-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 failed electronic control assembly in anti-static bag, observe above instructions.

Stacking Kit Installation Instructions

To ensure safe and secure installation, please observe the instructions below.

WARNING

4 Secure the side bracket to the washer with a screw on the back of the bracket. Repeat

Steps 2, 3, & 4 for the other side.

Do not attempt this alone!

At least two people are required to lift and position the dryer on top of a washing machine!

Failure to heed this warning can result in serious physical injury and damage to the appliance.

5 Place the dryer on top of the washer by placing the legs as shown. Be careful not to pinch fingers between the washer and dryer.

Slide the dryer back against the stop on the side rail.

2

Stacking kit

Place the washer firmly on a stable, even and solid floor as product installation instructions describe in the owner’s manual.

Peel the protective paper from the tape on the side bracket.

6 Insert the front rail of the stacking kit. Push the front rail back against the stops on the side brackets.

3 Fit the side bracket firmly to the side of the top plate by attaching the double-faced tape to the top plate as picture shown.

7

Screw both sides of the front rail to the side brackets.

For further assistance, refer to section on Gas Requirements.

1. Make certain your dryer is equipped for use with the type of gas in your laundry room. Dryer is equipped at the factory for Natural Gas with a 3/8” N.P.T. gas connection.

2. Remove the shipping cap from the gas connection at the rear of the dryer. Make sure you do not damage the pipe thread when removing the cap.

3. Connect to gas supply pipe using a new flexible stainless steel connector.

4. Tighten all connections securely. Turn on gas and check all pipe connections (internal & external) for gas leaks with a non-corrosive leak detection fluid.
