ELECTRICAL OPERATION

COMPONENT FUNCTION

Determines the mode of operation; ON, OFF, or COOL down.
Controls the oven cavity lights.
Controls blower motor speed between High and Low settings.
Signals the end of a "Cook" cycle when cooking time expires.
Counts the "Cook" time of the product and signals the buzzer at the end of the cycle.
Allows the oven to operate when the doors are closed but stops the oven from operating
when the doors are opened.
Operates the oven cavity blower (convection fan).
Provides 240VAC power to the oven control circuit and blower motor (480VAC models
only).
Monitors temperature sensor and regulates the oven cavity temperature by controlling
1CON to energize the heating elements when the control calls for heat.
Protects the oven from temperatures above 550°F by removing power from the heating
circuit. Auto resets at 500°F.
Provides power to heating elements when energized. 1C is energized by the temperature
control when a call for heat is made.
Lit whenever the power switch (S1) is turned to ON or Cool Down mode.
Lit whenever temperature control is calling for heat.
Senses the oven temperature for the solid state temperature. The probe is an RTD
(resistance temperature detector) of the Thermistor type. As temperature increases the
resistance value decreases.
Circulates cooler air from outside the oven to cool components in the control area.
Protect control circuit.
