Section 2 Introduction
How Your Dryer Works
CYLINDER
LINT
FILTER
EXHAUST
FAN
HEATER
DUCT
DRY14S
The dryer uses heated air to dry loads of laundry. When the motor is started, the exhaust fan pulls air in
through louvers at the rear of the dryer and over the heat source (burner flame for gas and heating element
for electric). The heated air moves through the heater duct and into the cylinder, where it circulates
through the wet load. The air then passes through the lint filter, air duct, and exhaust fan, where it is
vented to the outdoors.

CYCLE COUNT “C”
NOTE: If collections are done on the dryer while the machines are in a cycle, the cycle count may not yet be
recorded, this count will appear on the next collection report. This happens if the collection occurs before
the end of the cycle on the dryer. Also, it must be noted that the method used for the cycle count is similar to
today's electro-mechanical counter and variances may occur due to the windows that exist. If the dryer is
unplugged during the last five minutes of the cycle, an extra count will appear. Also, if switch “C” is out of
