LINT

FILTER

Section 2 Introduction

CYLINDER

HEATER

DUCT

EXHAUST

FAN

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 adjustment, improper cycle counts may appear.

22. CONTROL PANEL, TEMPERATURE SWITCH, PUSH-TO-START SWITCH AND INDICATOR LIGHT Refer to Figure 7

a. On Card Reader Models, remove panel lock

(if present).

NOTE: Several turns of the key may be required to remove panel lock.

b. Remove two control panel attaching screws and

lift assembly off cabinet top.

c. Disconnect all wires to temperature switch,

PUSH-TO-START switch and INDICATOR LIGHT and remove ground clip and screw holding ground wire to cabinet top and control panel.

NOTE: Refer to appropriate wiring diagram when reconnecting wires.

d. Loosen setscrew holding temperature switch

knob to shaft and pull knob off shaft.

To Test Push-To-Start Switch

1. Unplug dryer from electrical supply and disconnect wires from switch terminals.

2. Disconnect all wires from switch.

3. Set Volt-Ohm meter on OHMS scale and calibrate at appropriate scale.

4. Place meter probes on switch terminals. You should see an “infinite” reading on the meter.

5. With probes attached to switch, press the start switch button. You should read “0” Ohms.
