control switch is placed in the ON position. The convection motor should shut off when the oven door is opened unless the fan control switch is placed to the COOL DOWN position. In the COOL DOWN position the oven door microswitch is bypassed so that the convection motor will run while the oven door is open to rapidly lower the oven temperature.
SEQUENCE OF OPERATION (C Model)
Refer to schematic diagram
Initial Conditions
1.Conditions.
A.The oven has been properly installed and the power plug is plugged into a wall outlet that agrees with the required voltage on the rating plate.
B.The oven manual gas shutoff valve is in the OPEN position.
C.The oven door is open.
D.The oven pilot is lit.
E.The temperature control is set to the desired temperature.
2.Turn the fan control switch to ON.
A.Power is applied to one side of the convection motor.
B.Power is applied to one side of the solenoid.
3.Oven door closed.
A.Oven door microswitch contacts will close.
B.Power is applied to the other side of the convection motor and it will begin to rotate.
i.The convection motor centrifugal switch will close.
ii.Power will flow to the solenoid and the thermostat.
iii.The solenoid will open the gas valve and gas will flow to the burner.
iv.Oven temperature will be controlled by the oven control valve.
4.Oven door opened.
A.With the fan control switch in ON, the oven door microswitch contacts will open and power will be removed from one side of the convection motor.
i.The centrifugal switch will open and power will be removed from the solenoid and the thermostat.
ii.The solenoid will close the gas valve and shutoff the gas to the burner.
iii.Pilot remains lit.
B.With the fan control switch in COOL DOWN, the oven door microswitch is bypassed to the convection motor.
i.The convection motor will continue to run.
ii.The oven door microswitch will remove power to one side of the
