SAFETY

GAS

Check the local laws and regulations concerning the installation and connection

of gas. In most localities, it is illegal to connect gas piping, re-jet or adjust burners,

or repair gas-fired equipment unless you are certified so to do.

ELECTRIC

The gas dryer uses 120 VAC. The electric dryer uses 240 VAC. Even when these

products are turned OFF, there is live voltage on some of the internal terminals.

Always unplug the appliance before opening the case or servicing.

SERIAL NUMBER IDENTIFICATION

The serial number is unique to each product. It gives information concerning the

time and place of manufacture. The serial number is required to be paid for

warranty service and to get the correct part in the event a running production

change was made. Some models may have four (4) letters instead of two (2) for

the product code number. The third and fourth letters are significant only to the

manufacturing facility.

This chart will help you decode the serial number.

INTRODUCTION

The 9577/9588 dryer is very similar to other LG dryers with the exception of the

front panel and the control panel. The control panel is designed to allow the

customer to choose the location of either the top or the bottom, which allows for

easier access to the controls when the dryer is stacked on top of the washer.

(See

page 42.) The dryer is shipped from the factory with the control panel in the

lower position.

CONTROLS

The control panel features discrete buttons for each selection rather than

requiring the user to cycle through numerous choices to pick one.

A couple of buttons serve double functions. Pressing and holding RACK DRY will

turn the Child Lock ON or OFF. Pressing and holding CUSTOM PROGRAM will

store the customer’s favorite setting (one that is used most of the time.)

The main control board is located in the top of the machine rather than in the

front panel. The communication between the main control board and the control

panel is handled by a UART (Universal Asynchronous Receiver Transmitter) and

a 7-wire cable rather than by a 28-wire cable as in previous models. This

simplification is what makes it possible to have a re-locatable control panel.

INSTALLATION

The 9577/9588 dryer is designed to be used stacked on top of a WM2496

washer, so the control panel is shipped in the lower position. It can be converted

easily to be used as a conventional dryer next to a washer. The customer can do

this himself. (See page 42 of this training manual.)

The 9577/9588 dryer can be installed in a laundry closet if the clearance

guidelines are met. (See drawing, above.) It does not matter whether the dryer is

stacked, as long as the closet door opening provides the appropriate vertical

clearance for lifting and stacking in the closet.

ACCESSORIES

The 9577/9588 dryer is shipped with a drying rack and a stacking kit. The

pedestal is optional. The dryer is designed to stack on the matching WM2496

washer. Both products can be stacked on a single pedestal, if desired, but the

dryer must always be on top of the washer.

DRYING RACK STACKING KIT PEDESTAL

INSTALLATION (RACK)

It’s simple!

Open the dryer door.

Set the rack in place.

Select RACK DRY.

(2nd button from top on the option row

on the right of the panel)

Press START.

Be sure the front of the rack is

properly situated in the notches on

either side of the filter. The back of the

rack should rest on the drum and

allow the drum to rotate.
