FULL SIZE GAS CONVECTION OVENS - ELECTRICAL OPERATION

Temperature Probe	Senses the oven temperature for the solid state temperature control or the
	computer control. On WKGD/WKGDX models, 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.
	On WKGC/WKGCX models, the probe is a J type thermocouple.
Gas Valve (Dual Solenoid)	Allows gas flow to the burner when the 1st valve (safety) and 2nd valve
	(main) solenoid coils are both energized.
Cooling Fan	Circulates cooler air from rear of oven forward to cool components in the
	control area.

Mechanical Temperature Control

KX Thermostat (WKG/WKGX) . . . . Regulates the oven cavity temperature by controlling the heat relay (R3) through the blower motor centrifugal switch contacts. On ROAST & HOLD models only, power is first connected through one set of (R4) normally closed contacts (N.C.) then through the centrifugal switch contacts on the motor.

Hold Thermostat (KX) . . . . . . . . . . Holds the oven cavity temperature at 160°F after ROAST (then hold) time expires. For the oven to operate on the Hold thermostat, the ROAST & HOLD timer must be used and the Function Switch (S3) must be set to. Available on models with Roast & Hold option only.
