Operation Overview
The typical dryer cycle progresses as follows:
1. A cycle is selected and the START/PAUSE button is pressed.
2. The motor is activated. The drum motor rotates the drum at a speed of approximately 50 RPM
(revolutions per minute).
3. The heater elements are activated. The elements cycle on and off to achieve the desired temperature
throughout the heating portion of the cycle.
4. If sensor drying is selected, the heater elements are activated. The elements cycle on and off until the
load has achieved the desired dryness level.
5. If timed drying is selected, the heater elements are activated and cycle on and off for the selected time at
the selected temperature.
6. The heater coils discontinue operation after the dryness level or elapsed time has been achieved.
7. The motor continues operating until the clothes temperature drops below specifi ed temperature (cool
down).
9. The display turns off.
Air enters the dryer cabinet, passing through the heating elements and into the drum. The hot air heats the
wet clothes, gradually removing their moisture in the form of water vapor. The moist air is vented through
the dryer exhaust. Overall heater temperature is regulated by means of an inlet temperature thermostat,
located on top of the heater assembly, and an outlet thermistor, located at the blower. A safety thermostat,
located on top of the heater assembly, and an outlet thermostat, located near the blower, cycle the heating
elements if temperatures are excessive. If the thermostat reaches a temperature beyond its maximum
temperature rating, power will be interrupted to the heating elements and the control board, thereby
terminating dryer operation.

AIR FLOW AND SEALS
Proper air fl ow through the dryer is essential for normal operation of the temperature control and safety
systems. The back cover must be in place for proper airfl ow.
Air is pulled into vents in the rear of the cabinet. The temperature of the air rises by passing thru the
electric heaters. This heated air enters thru holes in the back of the drum and dries the clothes load. The air
containing moisture is pulled through the lint fi lter, where lint is screened by the fi lter, and enters the outlet
duct. The air in the outlet duct is pulled by the blower. From the blower the air is pushed out of the exhaust
system.
Any air leaks between the air inlet and the blower such as drum front felt or outlet duct to duct cover sealing
will result in improper temperatures. The air being pulled down the duct outlet to the outlet thermostat will be
cooler than normal, giving this thermostat a false indication (delayed or no trip).

Note: The 2 touch sensors in the fi lter inlet are not
replaceable. To replace the sensors, replace the fi lter
inlet.
The sensors are connected to the main control
board. The sensors are spaced approximately ½-in.
apart, which creates an open circuit to the control.
The control board utilizes a low-voltage •
capacitor that charges to approximately 5 VDC
when the circuit is open and discharges to less
than 1 VDC when the circuit is shorted.
When wet clothes tumble across the two •
sensors, the clothes create a very low resistance
between the sensors, which discharges the
capacitor.
As the clothes become dry, their resistance •
value increases and the charge across the
capacitor builds to approximately 5 VDC.
Operation of the touch sensors can be checked •
by using the service test mode. (See Service Test
Mode.)
Proper leveling of the dryer is vital for accurate •
sensor drying. If the front of the dryer is raised
too high, clothes will tumble toward the rear of
the drum, preventing contact with the sensors.
This could produce a false dryness reading.
Touch Sensors
The touch sensor consists of 2 sensors permanently
attached to the fi lter inlet.
To remove the touch sensor assembly:
Open the door and remove the lint fi lter.1.
Remove the 2 Phillips-head screws that attach 2.

centrifugal switch that serves two purposes:
Disengages the motor start winding.•
Closes the circuit contacts for the heat source. •
(Heat source contacts are No.1 red wire and
No.2 black wire.)
The overload protector and switch are internal
components of the motor and cannot be replaced
separately.
The motor circuit, CN2 gray to RY1 blue, has an
approximate resistance value of 1.7 Ω (equivalent
resistance of start and run windings).
A reading of approximately 3.6 Ω indicates an open
winding, stuck open start switch, or open wiring.
