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 t he power switch)
FAN SPEED SWITCH ..........Controls speed of oven cavity blower motor. (Electric ov ens)
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 Ov ens)
GAS VALVE .................Allows gas to flow to burner. (Gas ovens)
SPARK MODULE .............Generates spark for burner ignition, monitors flame, control s 15 second
purge time and 10 second ignition time and power to gas v alve. (Gas ovens)
POWER LIGHT...............Lit whenever the power switch is ON. (Soli d stat e control)
HEAT LIGHT.................Lit whenever burner or heaters are operating. (Solid stat e c ont rol)
NO IGNITION LIGHT ..........Lit when sensor fails to detect flame. (Soli d state control - Gas oven)
CONTACTOR................Powers heater elements. (Electric ov ens)
FUSE .....................Protects control circuit. (Electric ovens)
