Air enters the dryer cabinet, passing thru the heating elements and into the drum. The hot air heats the wet

clothes and gradually removes 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 two temperature sensors: an inlet

sensor located near the heating elements, and an outlet sensor located at the blower. An additional safety

thermostat, located near the heating elements, shuts off the heating elements if they overheat. Also, the

outlet backup thermostat, located near the blower, provides additional safety and cycles the heaters if

temperature goes above the outlet temperature range.

The typical dryer cycle progresses as follows:

1. A cycle is selected and the start key is pressed.

2. The motor is activated.

3. The heater elements (burner for gas models) are activated. The elements (burner) 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 (burner for gas models) are activated. The elements

(burner) cycle on and off until the load has achieved the desired dryness level.

5. If timed drying is selected, the heater elements (burner for gas models) are activated and cycle on and off

for the selected time at the selected temperature.

6. If STEAM DEWRINKLE or STEAM REFRESH is selected, the water valve is activated during heater elements

cycle on time (burner on time for gas models). See Cycle Matrix Chart on page 15.

7. The heater elements (burner for gas models) discontinue operation after the dryness level or elapsed time

has been achieved.

8. The motor continues operating until the clothes temperature drops below speciﬁ ed temperature (Cool

Down).

9. The display turns off.
