WARNING !

WHAT TO DO IF YOU SMELL GAS:

IMPORTANT SAFETY NOTICE

The information in this service guide is intended for use by individuals possessing adequate backgrounds of electrical, electronic, and mechanical experience. 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.

FEATURES AND BENEFITS

INSTALLATION INSTRUCTIONS

Open the door.

Hold the dryer rack with both hands.

Put the dryer rack into the drum

Make sure that dryer is evenly placed right onto the drum inside and door rim.

Dryer Rack Installation Instructions

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

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

Peel protective paper off the tape from the stacking kit side bracket.

Fit the stacking kit side bracket firmly to the side of top plate by attaching the doublefaced tape to top plate as picture shows.

Secure stacking kit side bracket to the washer with a screw on the back of bracket. Repeat Steps 2, 3, 4 for the other side.

Place the dryer on top of the washer by fitting legs as shown in the picture. Avoid finger injuries - be careful not to pinch fingers between the washer and dryer. Slide washer slowly backwards to the stopper of kit.

Insert the front stacking kit. Push the front stacking kit back to the stoppers of side stacking kit.

Screw both sides of the front kit.

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

Stacking kit

Do not attempt installation with one person.

Incorrect installation procedure can cause serious accidents and physical Injuries.

The weight of the dryer and the height of installation makes the stacking procedure too risky for one person. This procedure should be performed by 2 or more experienced service personnel.

Use the instructions at this section if your home has a 3-wire receptacle (NEMA type 10-30R) and you will be using a UL listed, 120/240 volt minimum, 30 amp, dryer power supply cord.

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

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 1

/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 at this section if your home has a 4-wire receptacle (NEMA type 14-30R) and you will be using a UL listed, 120/240 volt minimum, 30 amp, dryer power supply cord.

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 power cord is in right position.

Before measuring resistance, be sure to turn Power off, and do voltage discharge. (When discharging, contact the metal plug of Power cord with earth line.)

While operating, Heating will not work. Drying time takes longer.

After turning Power off, measure the resistance.

Check Controller.

Check Harness-linking Connector.

Check Motor. Check if the value of measured resistance is below 1Ω between terminal

and at RUN condition.

YES

• Check Motor and replace it.

1. Is resistance between Heater terminal and below 18 ~ 22Ω?

2. Is resistance between Heater terminal and below 18 ~ 22Ω?

3. Is resistance between Heater terminal and below 9 ~ 11Ω?

YES

• Replace Heater.

Check if the value of measured resistance is below 1Ω between terminal TH2 (Safety Thermostat).

YES

• Replace TH2 (Safety Thermostat)

Check if the value of measured resistance is below 1Ω between terminal TH3 (HI-Limit Thermostat).

YES

• Replace TH3

Trouble Symptom

Measurement Condition

When measuring power, be sure to wear insulated gloves, to avoid electric shock.

While operating, Heating will not work. Drying time takes longer.

With dryer power on

• Harness check

• Controller change

When measuring terminal resistance on “Valve 1”, “Valve 2”, Value is more than1.5 ~ 2.5kΩ? (Measure after Off )

YES

• Change Valve

• Check thermostat Hi limit Safety

Igniter operates? (after 1 min, Igniter becomes reddish)

YES

• Check Igniter &

Frame detect

When measuring Valve 2 voltage, Value is more than AC 90V? (10 sec after Igniter off)

YES

• Check Gas

connection or Gas supply

When measuring Valve 1 voltage, More than AC 90V?

YES
