Air enters the dryer cabinet, passing thru the heating elements (gas combustion chamber for gas models),

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 heating temperature is regulated by

means of 2 temperature thermostats: an inlet control thermostat located near the heating elements and

an outlet control thermostat located at the blower. (Note: Gas models use only an outlet control thermostat

for overall temperature regulation.) A safety thermostat, located near the heating elements (diffuser for

gas models), cycles the heating elements (burner for gas models), if overheating occurs. Also, the high limit

thermostat, located near the heating elements (diffuser for gas models), provides additional safety and

interrupts motor and heater operation if temperature rises above safe limits.

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 coils (burner for gas models) are activated. The coils (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 coils (burner for gas models) are activated. The coils (burner) cycle

on and off until the load has achieved the desired dryness level.

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

the selected time at the selected temperature.

6. The heater coils (burner for gas models) 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).

8. The display turns off.
