Microwave Combination Wall Ovens
OPERATION
The Main Oven 120 VAC section.
With the Appliance Manager powered up and the connection between the Appliance Manager
connector P1 and the User Interface connector J15, the two electronic controls are able to
communicate with each other. Information the consumer inputs into the Control Panel Assembly/User
Interface is transferred to the Appliance Manager so that the necessary relays on the board open and
close. The Appliance Manager is also interpreting information from the LOGIC Circuits about the oven.
The Appliance Manager needs everything about the oven to be correct before it will proceed with the
customer’s request. If the LOGIC circuits are not right, the control will produce an error code. The
circuit below shows how the power supply is delivered.
The L1 circuit provides all the components with power through the P5-7 connection. Once a relay closes
(K4-K8) it completes a circuit through the component to the Neutral side of the line.
