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.

motor assembly.

2. Remove wires from one side of each switch.

NOTE: Refer to appropriate wiring diagram when rewiring timer.

3. Manaully advance timing cam to disengage it

from ratchet wheel.

4. Set meter to read Ohms and apply leads on

terminals of each switch in turn. You should read the following: Switch A = “zero ohms (closed). Switch B = “zero” ohms (closed). Switch C (if present) = “infinite” (open)

RATCHET

WHEEL

5. Manually advance timing cam until it engages with ratchet wheel and the first “click” is heard. Switch B should now read “ifinite” (open).

6. Continue to rotate timing cam until second “click” is heard. Switch B should remain open. Switch A should read “infinite” 9open) and Swtich C (if present) should read “zero” Ohms (closed).

7. Timing Motor Apply live power to timing motor leads - Timing motor should advance timing cam.

(closed).

b. Heat circuit test - L1 and H = “zero” ohms

(closed).

c. Timer Motor test - L1 and N =

approximately 1100 Ohms or apply live power to timer motor terminals and motor should run.
