MODEL GCO4D/GCO6D

MASTER SWITCH	— ON — turns oven control circuits on.
	OFF — turns oven control circuits off.
OVEN COOL SWITCH	— Allows the fan motor to run with the doors ajar to speed oven cooling.
LIGHT SWITCH	— Turns lights in the oven on or off.
THERMOSTAT	— Controls oven temperature during cooking operation.
TIMER	— Use to set cooking cycle time. Alarm sounds continuously when elapsed
	time counts down to 0; oven does not turn off. Turn timer to OFF position
	to stop alarm. When oven is not in use, keep timer at OFF position.
ON LIGHT (Amber)	— Lit when Master Switch is positioned at ON.
HEAT LIGHT (White)	— Comes on and goes off when the burner cycles on and off.
NO IGNITION LIGHT (Red)	— Comes on if burner fails to ignite after the third try. When lighting the oven,
	the NO IGNITION LIGHT cycles ON during the 5-second purge and OFF
	during the 7-second ignition trial.
2-SPEED MOTOR — LO / HI — Adjusts air velocity in the oven.
GAS VALVE	— When ON, allows gas to flow to the ignition system.
