ELECTRICAL OPERATION
COMPONENT FUNCTION
POWER SWITCH . . . . . . . . . . . . . Controls power to oven.
COOLDOWN SWITCH . . . . . . . . . Prevents heaters from operating and allows fan to run. (On some solid state
control models, this switch is combined with the power switch)
FAN SPEED SWITCH . . . . . . . . . . Controls speed of oven cavity blower motor. (Electric ovens)
SOLID STATE CONTROL . . . . . . . Controls oven temperature.
TIMER . . . . . . . . . . . . . . . . . . . . . Signals end of timed baking. Does not shut heater or burner off. (Solid state
control)
ELECTRONIC CONTROL . . . . . . . Controls oven temperature, cook and hold mode, pulse mode and time.
BLOWER MOTOR . . . . . . . . . . . . Circulates air inside oven cavity. (Contains centrifugal switch for gas ovens)
(2 speed electric ovens)
DOOR SWITCH . . . . . . . . . . . . . . Allows heating of oven, only when the doors are closed.
TEMPERATURE PROBE . . . . . . . Senses temperature of oven cavity for the solid state control and electronic
control.
SOLID STATE RELAY . . . . . . . . . Controls power to blower motor. (Electronic Control)
TRANSFORMER . . . . . . . . . . . . . . Provides 12 and 6 VAC power. (Electronic Control)
TRANSFORMER . . . . . . . . . . . . . . Provides 24 VAC power to the spark ignition control if the centrifugal switch
(part of blower motor) is closed. (Gas Ovens)
GAS VALVE . . . . . . . . . . . . . . . . . Allows gas to flow to burner. (Gas ovens)
SPARK MODULE . . . . . . . . . . . . . Generates spark for burner ignition, monitors flame, controls 15 second
purge
time and 10 second ignition time and power to gas valve. (Gas ovens)
POWER LIGHT . . . . . . . . . . . . . . . Lit whenever the power switch is ON. (Solid state control)
HEAT LIGHT . . . . . . . . . . . . . . . . . Lit whenever burner or heaters are operating. (Solid state control)
NO IGNITION LIGHT . . . . . . . . . . Lit when sensor fails to detect flame. (Solid state control - Gas oven)
CONTACTOR . . . . . . . . . . . . . . . . Powers heater elements. (Electric ovens)
FUSE . . . . . . . . . . . . . . . . . . . . . Protects control circuit. (Electric ovens)
