COMPONENT FUNCTION

Power Cord .............................. Connects range to power source.
Solenoid Valve ......................... The solenoid is a normally closed valve. The solenoid opens when electrical
Door Switch ............................. Opens circuit to convection motor and solenoid when oven door is opened.
Single Phase
Convection Oven Motor .......... The convection oven motor circulates overheated air. The motor electrical
Junction Box ............................ Connection point for electrical wires.

SEQUENCE OF OPERATION

Refer to schematic diagram.
Initial Conditions
1. Conditions.
A. Power switch off.
B. Oven door open.
2. Turn power switch on.
A. Power applied to one side of convection oven motor and one side of solenoid.
B. Power applied to common terminal on door switch.
3. Door switch closed.
A. Power applied to other side of convection oven motor and motor operates.
B. Power applied to other side of solenoid. Solenoid operates and opens gas flow to burner.
4. Door opened.
A. Power removed from solenoid cutting off gas flow.
B. Power is removed from convection oven motor causing motor to stop.

ELECTRICAL OPERATION

voltage flows to the solenoid coil. The coil is grounded on one side and
energized with voltage on the other side. When voltage flows a magnetic field
is created drawing on a spring-loaded plunger. When activated the plunger
opens allowing gas to flow to the burner assembly.
circuit is routed through door switches. The door closes the switch and allows
voltage to flow from the door switch to the motor. The motor should operate
with the door closed and shut off when the door is opened.
