ELECTRICAL OPERATION
COMPONENT FUNCTION
Power Switch (S1) .... Determines the mode of operation; ON, OFF, or COOL down.
Oven Light Switch
(S3) ...................
Controls the oven cavity lights.
Fan Speed Switch
(S2) ...................
Controls blower motor speed between High and Low settings.
Alarm/Buzzer ......... Signals the end of a "Cook" cycle when cooking time expires.
Cook Timer ........... Counts the "Cook" time of the product and signals the buzzer at the end of the cycle.
Door Switch .......... Allows the oven to operate when the doors are closed but stops the oven from operating
when the doors are opened.
Blower Motor ......... Operates the oven cavity blower (convection fan).
Transformer .......... Provides 240VAC power to the oven control circuit and blower motor (480VAC models
only).
Solid State
Temperature
Control ...............
Monitors temperature sensor and regulates the oven cavity temperature by controlling
1CON to energize the heating elements when the control calls for heat.
High Limit
Thermostat ...........
Protects the oven from temperatures above 550°F by removing power from the heating
circuit. Auto resets at 500°F.
1C .................... Provides power to heating elements when energized. 1C is energized by the temperature
control when a call for heat is made.
Power ON Light ....... Lit whenever the power switch (S1) is turned to ON or Cool Down mode.
Heat Light ............ Lit whenever temperature control is calling for heat.
Temperature Probe ... Senses the oven temperature for the solid state temperature control or computer control.
On oven models using the solid state control, converts the temperature into a resistance
valve which is monitored by the temperature control board. The probe is an RTD
(resistance temperature detector) of the Thermistor type. As temperature increases the
resistance value decreases.
Cooling Fan .......... Circulates cooler air from outside the oven to cool components in the control area.
Fuses ................. Protect control circuit.
