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.
