Installation Highlights
Exhaust Information WARNING: Use only metal 4-in. duct. Do not use
duct longer than specified in the Exhaust Length table.
Exhaust longer than specified will:
Increase the drying times and the energy cost.
Reduce the dryers life.
Accumulate lint, creating a potential fire hazard.
The correct exhaust installation is your re­sponsibility. Problems due to incorrect instal­lation are not covered by the warranty.
The maximum allowable length of the exhaust system depends upon the type of duct, the number of turns, the type of exhaust hood (wall cap), and all conditions noted in this section. Both, rigid and flexible metal ducts are shown in the following table.

Exhaust System Checklist
Hood or Wall Cap
Note: To check airflow restrictions on the electric dryer model, check amperage from the black wire to pin #8. If 22.2 amps are shown and the relay does not trip within 10 minutes, the airflow is OK. If the relay trips the inlet thermostat withinin the first 5 minutes and reads 11.1 amps, then airflow is restricted.
Separation of Turns For best perfor mance, separate all tur ns by at
least 4 ft of straight duct, including the distance between the last turn and the dampened wall cap.
Turns Other Than 90°
One turn of 45° or less may be ignored.
Two 45° tur ns should be treated as one 90° turn.
Each turn over 45° should be treated as one 90°
turn.
Sealing of Joints
All joints should be tight to avoid leaks. The male end of each section of duct must point away from the dryer.
Do not assemble the ductwork with fasteners that extend into the duct: they will serve as a collection point for lint.
Duct joints can be made airtight and moisture­tight by wrapping the overlapped joints with duct tape.
Insulation Duct work that runs through an unheated area or
is near air conditioning should be insulated to reduce condensation and lint buildup.
Terminate in a manner to prevent back drafts or entry of birds or other wildlife.
Termination should present minimal resistance to the exhaust airflow and should require little or no maintenance to prevent clogging.
Never install a screen over the exhaust duct.
Wall caps must be installed with opening
pointed down at least 12 in. above ground level or any other obstruction.
If roof vents or louvered plenums are used, they must be equivalent to a 4-in. dampened wall cap in regard to resistance to airflow, prevention of back drafts, and maintenance required to prevent clogging.
Exhaust Connection WARNING: To reduce the risk of fire or personal
injury:
This dryer must be exhausted to the outdoors.
Use only metal duct.
Do not terminate exhaust in a chimney, any gas
vent, under an enclosed floor (crawl space), or into an attic: the accumulated lint could create a fire hazard.
Provide access for inspection and cleaning of the exhaust system, especially at turns. Inspect and clean at least once a year.

Using Flexible Metal Ducts
If rigid all-metal duct cannot be used, then flexible all-metal venting can be used, but it will reduce the maximum recommended duct length. In special installations when it is impossible to make connec­tion with the above recommendations, UL-listed clothes dryer transition duct may be used as transition venting between the dryer and wall connection only. The use of this ducting will affect dry time.
If flexible transition duct is necessary, you must adhere to the following directions:
Use the shortest duct length possible.
Stretch the duct to its maximum length.
Do not crush or collapse the duct.
Never use transition duct inside the wall or
inside the dryer.
Avoid resting the duct on sharp objects.
Venting must conform to local building codes.
Cut The Standard Exhaust Duct To Proper Length. Avoid Bunching Of The Duct Behind The Dryer.
For Straight Line Installation, Connect The Dryer Exhaust To The Wall Using Duct Tape

Operating Characteristics
Note: Not all models have the same features. Your
model may vary from those discussed in this manual.
Basic Dryer Operation
The L3 Dryer contains both sensor dry and timed dry options.
The six desired dryness level as measured by the rod voltage signal. Each cycles settings control the heated dry time and specific cooldown time. At the end of cooldown, the machine stops the drying operation and signals the end of the cycle.
During dries the load for the specified time, including extended tumble time (if selected). At the end of the selected time, the dryer ceases to tumble and heat the clothes, and signals the end of the cycle.
Note: Only one sensor or timed dry cycle can be selected at any time. A new cycle selection will override the previous one.
SENSOR DRY cycles
TIMED DRY cycles
, the dryer tumble-
dry clothes to a
voltage signal.
When the load reaches the Damp threshhold, the dryer calculates the required remaining time to dry the load to the specified dryness level. The estimated remaining time appears in the display, the countdown resumes, and the Sens- ing LED turns OFF. The countdown continues until the end of the cycle, including cooldown time.
At the end of the cycle, the unit stops drying, the Sensor Dry LED turns OFF, the display reads
00,” and the Clean Lint Filter LED turns ON.
The display and Clean Lint Filter LED turn OFF
when the user 1) opens the door, 2) presses Stop/Cancel, or 3) starts another cycle selec­tion.
Speed Dry When the Speed Dry button is pushed, the letters
SP appear in the digital display. When the user presses Start/Pause, the display enters Variable Speed Racetrack mode until the Damp threshhold is calculated, then it shows “SP” for the entire cycle.
One Touch Sensor Dry Cycles
Cottons, Mixed Loads, Easy Care/Perm Press, Knits/Sweaters, and Delicates
These buttons use predetermined dryness levels (either Dry or Less Dr y) and temperatures (Extra Low to High/[Regular]) to dry clothes. The Sensor Dry LED is ON until the end of the cooldown period.
The cycles proceed as follows:
Pressing a cycle button will cause the display to show the default numbers for that cycle.
Once the user presses the Start/Pause button, the display begins the normal countdown, and the Sensor Dry LED turns ON.
When the default minimum time for the selected cycle is reached, the display enters Variable Speed Racetrack mode and the Sensing LED begins to flash. Four speed levels are available; the speed will be determined by the sensor rod
One T ouch Timed Dry Cycles
DRYEL, De wrinkle, and Air Dry These buttons use Medium or (for Air Dry) no heat

DRYEL
runs for 20 minutes, and Air Dry runs for 10 minutes. The Timed Dry LED turns ON until the end of the
cycle (including cooldown), then the Clean Lint Filter LED turns ON as described earlier.
DRYEL System DRYEL helps “dry clean only” clothes look and
smell clean and fresh. While not a complete dry cleaning system, DRYEL uses a perfumed pad and nylon bag to eliminate odors (such as smoke and perspiration) and wrinkles from clothes. The DRYEL kit, available in retail stores, also in­cludes a spot remover for removing small stains.
Caution: Using any other bag with the DR YEL system may damage the clothes or the L3 Dryer.

Start/Pause
When this button is pushed either for the first time or after the Stop/Cancel button is pushed, the display defaults to the last cycle run and the Start/ Pause button’s LED light flashes 0.5 seconds ON and 0.5 seconds OFF, indicating Action Needed to Start.
If the button is pushed after a cycle is selected, the machine starts per the selected cycle and options unless the door is open. If the door is open, the button flashes and no action occurs.
Dryness Levels Note: Dryness Level buttons are locked out for
One Touch Timed Dry Cycles. Four dryness levels, including More Dry, Dr y, Less
Dry, and Damp, are available. When a Dryness Level button is pushed, no other button is affected with one exception. When a Dryness Level button is pushed after a One Touch Timed Dry Cycle button or the Antibacterial button has been selected, the new dryness setting appears in the display, and the time matr ix is updated. However, the heater setting does not change; default heater settings will be performed.
Timed Dry Only
When any Timed Dry Only button is pushed, the cycle defaults to a Medium heat setting and no specific Dryness Level.
The Timed Dry LED turns ON until the end of the cycle (including cooldown), then the Clean Lint
Filter LED turns ON as described earlier.
Heat Setting
(High/[Regular], Medium, Low, and Extra Low) Note: Heat Setting buttons are locked out for the
Air Dry cycle. When any Heat Setting button is pushed, that
option will be selected. No other button will be affected with one exception. When a Heat Setting button is pushed after the Knits/Sweaters, Delicates, Dryel, Dewrinkle, or Antibacterial cycle has been selected, the new temperature setting appears in the display and the time matrix is
On initial power-up, either from the factor y or after a power outage, pressing the Start/Pause button displays the default settings for the Cotton Sensor Dry cycle.
If the button is pushed in midcycle, the unit enters Pause mode. Drying operation stops and the Start/Pause button’s LED flashes. Pressing the button again resumes drying operations.
Stop/Cancel
Pushing this button deactivates all selections, and all LEDs turn OFF. If the machine is running when this button is pushed, the machine turns OFF.

Sensor Rod Circuit Description
Sensor Rods Table
The moisture-sensing rods are part of a circuit that is designed to utilize a low-voltage capacitor that charges to 5 V when the circuit is open, and discharges to 1 V when the circuit is shorted. The gap in the circuit is the space between the rods. When the wet clothes touch the two rods, they create a short, which discharges the capacitor. When the clothes become dry, they cannot short the circuit and the charge across the capacitor builds to 5 V. A voltage of 1 V across the capacitor read by the PCB indicates wet clothes. As the clothes are dried, the voltage increases, and finally 5 V across the capacitor indicate completely dry clothes.
In the diagnostics mode, a code of S0 indicates a normally open circuit (the capacitor is charged properly). The code E2 indicates a shorted capaci- tor or some other problem on the board. To check the discharging of the capacitor, touch the rods with your hands, shorting the two rods for at least 5 seconds. The S0 will change to SS, indicating that the capacitor discharged properly. No change from S0 indicates that either the rods are not connected to the board or there is some other problem on the board.
Note: If you want to repeat the test, wait for at least 45 seconds to fully charge the capacitor.

START/PAUSE
Press twice to select the last cycle you used and start the dryer.
If you have selected a new cycle, press once to start the cycle.
If the dryer is running, press once to interrupt the cycle; press again to continue the cycle.
STOP/CANCEL
This pad should
not
be used to interrupt or pause a cycle.
Pressing this pad will cancel the current settings and the settings will be lost.
Estimated Time Remaining
Each time the dryer is used, it “learns” what types of loads you dry most often. It takes this data and determines the approximate time it will take the load to dry.
As the cycle begins, you will see the approximate total cycle time in the display. Then “racetrack lights” will flash in the display, in a clockwise direction, and the
SENSING
light will flash. This means the dryer is continuously monitoring the amount of moisture in the load. The racetrack lights will continue until the dryer senses a low level of moisture in the load. At that point, the dryer will calculate and display the approximate time remaining.
Racetrack lights

About cycle options.
BEEPER
Alerts you that the cycle is complete. The beeper will continue to sound every two minutes for the next 6 minutes, until the clothes are removed. The clothes should be removed when the beeper goes off so wrinkles wont set in.
EXTEND TUMBLE
Minimizes wrinkles by adding approximately 20 minutes of no-heat tumbling after clothes are dry. The beeper will sound every 90 seconds to remind you to remove the clothes. The
EST. TIME REMAINING
display will show 00.
ADD TIME
This option can be used to extend drying time at the end of any cycle. 10 minutes is added each time the pad is pressed.
ANTI BACTERIAL (on some models)
This option can only be used with the
COTTONS
or
MIXED LOADS
cycles. This option reduces certain types of bacteria by 99.9%, including: Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae*. The anti-bacterial process occurs when high heat is used during a portion of the drying cycle.
NOTE:
Do not use this cycle on
delicate
fabrics.
* The Anti-Bacterial Cycle is Certified by NSF International (formerly National Sanitation
Foundation) to NSF Protocol
P9 Sanitization Performance of Residential Clothes Dryers.

Note: See schematic for proper switch connections.
1. Heater coil resistance is shown on the wir ing schematic. Check for infinite resistance between any heater terminal and dryer cabinet. Heater failure could result from low airflow caused by improper sealing, kinked or excessive ducting, or excessive line voltage.
2. Other factors contributing to long dr y times or clothes conditions include load size, number of large or bulky items, ambient temperature, room size (if not exhausted outdoors), wetness of clothes, and washer rinse temperature.
3. Small loads (less than 3 lb) may develop static, causing clothes to cling to the drum surface (no tumble) and resulting in wrinkles, shrinkage, or melting. Use a fabric softener in the washer or dryer, or add two large bath towels to act as a buffer when drying.
