INTRODUCTION
The DISCOVERY dryer is very similar to other LG dryers with the exception of the LCD display on the control panel. The LCD display shows all the information formerly indicated by LEDs but also allows for scrolling instruction.
When a cycle is selected, the options are preset. They can be overridden by changing them using the option buttons. Pressing the buttons cycles through the available options. If an option is not available for a particular cycle, it is grayed out or not available for selection. For example, the EXTRA HOT wash is not available for the DELICATE cycle. The interior components remain the same: motor, belt, drum, and heat source (gas or electric). The gas model can be refitted with an orifice to allow the use of propane instead of natural gas. All such conversions and adjustments should be performed by a licensed and certified gasfitter. The DISCOVERY model also has an additional sensor in the exhaust stream to detect the moisture level more accurately for better drying results.
Page 6 of 60
DRYER Models DLE7177WM and DLG7188WM use the LED indicator panel instead of the newer LCD. The only difference is the type of display. The dryers function identically. The main and display PCB (Printed Circuit Board) will carry a different part number depending upon the type of display. Always order parts by model number and serial number to ensure receiving the correct parts.
The drying cycle is shown in the left window and the time remaining is show in the right. Feature selections like DRY LEVEL and BEEPER volume are indicated by LEDs on the panel.
The DISCOVERY line of dryers feature enhanced sensor drying. In addition to the drying sensor in the tub near the filter, there is an additional sensor in the exhaust stream to ensure the correct level of dryness is determined, from damp dry to very dry. The dryer can also be set manually to dry at a particular heat level and for a specified time.

SAFETY
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 licensed and certified so to do. It is the servicers responsibility to comply with all such regulation.

ACCESSORIES
DRYING RACK
STACKING KIT
PEDESTAL
The DRYING RACK is used to dry items that should not be tumbled, like sweaters, tennis shoes, etc. It should be removed and stored when not in use. The rack is included with the dryer. (See installation procedure, page xx.) The STACKING KIT is used to stack a dryer on top of a matching washer. (NEVER put a washer on top of a dryer!) The stacking kit should not be used in situation where there is the possibility of excessive vibration and movement of the washer, such as in a mobile home or an upper floor of a frame structure. The stacking kit is available as an optional purchase. (See installation procedure, page 11.) The PEDESTAL can be used under either the washer or the dryer. It is possible to stack a washer and dryer on a pedestal, but the dryer controls may be difficult to reach and the possibility of vibration and movement is greater. The pedestal is available as an optional purchase. (See installation procedure, page 13.) Pedestals are available in heights of 7 and 13.
INSTALLATION (RACK)
Its simple! Open the dryer door. Put the rack in place. Select RACK DRY (2nd button on right) Press START. Be sure the front of the rack is properly situated in the notches on either side of the filter. The back should rest on the drum and allow the drum to rotate. DLE8377xM/DLG8388xM DLE7177WM/DLE7188WM

GAS CONNECTION (Gas Dryer Only)
CAUTION! (This warning applies to both natural gas and propane.) Gas is both flammable and explosive. Use caution when working with gas. In most locations, installing and connecting gas is restricted to properly trained and licensed persons.
Always inspect joints and connections for a leak with a soapy solution. If you see bubbles, turn the gas off and open a window. If you smell gas, turn off the main valve and open a window. The gas dryer requires a 110 Volt, single-outlet, dedicated circuit. The cord is installed at the factory and no user-intervention is required.

MOTOR DIAGRAM and SCHEMATIC
To check the motor, turn the power off and allow the capacitor to discharge. The centrifugal switch serves as a safety device to turn off the fuel (gas or electricity) to the heater if the motor fails to rotate.
Page 24 of 60
DRYER SAFETY SWITCHES The centrifugal switch slides back and forth on the motors shaft to operate the contacts as shown in the previous diagram. This switch provides safety in the event the motor fails. When the motor is running, centrifugal force causes the weight (black wing in photo) to slide back toward the motor windings. This motion allows electricity to operate the heater (electric element or gas valve). If the motor stops, the weight slides forward and turns the power off. RUN POSITION STOP POSITION
There is an additional safety in the form of a belt switch that shuts off power to the electric motor if the belt breaks. Belt tension holds the switch closed. If the belt breaks, the switch opens and power to the motor is cut. When the motor stops, the centrifugal switch functions as a safety device to turn off the fuel (gas or electricity). The centrifugal switch includes a multipin connector (shown). The belt switch is simple. If the belt breaks, the spring pulls the lever down and it presses the switch.

GAS VALVE OPERATION
The gas valve is a two-stage valve. When the ignition sequence begins, the igniter is turned on and valve one opens. When the igniter reaches 370 F (188 C), the igniter is turned off and valve two is opened. If the flame detector does not detect ignition, valve two is closed and the process is restarted. If ignition occurs as planned, the drying cycle will operate.
