WARNING !

WHAT TO DO IF YOU SMELL GAS:

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.

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.

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.

■ 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.

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

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.

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.

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.

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.

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

• Do not use a stacking kit with a gas dryer in
potentially unstable conditions like a mobile
home.

Stacking kit

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.

the connection of a chassis ground to the neutral
connector. If this is not permitted, use option 3.

Review the following options to determine the appropriate electrical connection for your home:

Electric Dryer Only

If this type is available at your home. you will be
connecting to a fused disconnect or circuit breaker
box

Important : use 4-wire connection in the places such
as mobile homes and areas where 3-wire connections
is not available.

Prepare minimum 5ft(1.52m) of length in order for
dryer to be replaced.

First, peel 5 inch (12.7cm) of covering material from
end. Make a 5 inch of ground wire bared. After cutting

/2 inch (3.8cm) from 3 other wires. peel insulation
back 1inch (2.5cm). Make ends of 3 wires a hook
shape.

Then, put the hooked shape end of the wire under the
screw of the terminal block(hooked end facing rightward)
and pinch the hook together and screw tightly.

Use the instructions under option 1 if your home
homehas a 4-wire receptacle (NEMA type 14-30R).

If this type is available at your home. you will be
connecting to a fused disconnect or circuit breaker
box

1. Connect neutral wire(white) of power cord to center

terminal block screw.

2. Connect red and black wire to the left and right

terminal block screws.

3. Connect ground wire(green) of power cord to external

ground screw and move neutral ground wire of
appliance and connect it to center screw.

4. Make sure that the strain relief screw is tightened.

and be sure that all terminal block nuts are on tight and

(When discharging, contact the metal plug of Power cord with the Ground.)

During Diagnostic Test, tE1 and tE2 Error occur.
During operation, Heater would not turn off, or remains on.
Difference between actual and sensed temperature is significant.

After turning Power off, measure the resistance.

Check if resistance is in the range of Table 1
when measuring the 6 pin connector Pin
(Blue wire) and Pin (Red wire) connected
to Controller.

NO

YES

• Check if Control
and the 6 pin
connector are
properly
connected.

• Replace
Controller.

Check Harness-linking connector.

Take the 6 pin Connector

from the Controller.
