Explatin of the function of primary parts.
CN101
This is to supply power with SMPS.
CN201
This is connector which is connected with Sub PCB to communicate.
CN202
When do micom revision, connect to micom writer.
And this connector which is connected with Touch PCB to communicate.
CN301
This connector which is connected with oven sensor.
CN401
This is connector which is connected with Door plunger switch and Door lock
switch, partition switch.
CN501
This connector which have Door plunger switch, upper lamp and
relay of upper convection fan connected.
CN502
This connector which have lower lamp and relay of lower convection fan
connected.
RY-Source Relay(RY501)

DLB Relay(RY502)
Circuit is designed to have broil relay or convection relay worked after DLB relay
is being worked by Double line break. (It will not be problem with reversing the
order in inserting Red)
Broil Relay(RY503),
Bake Relay(RY504),
Relay(RY505)
Broil relay(Ry503), Bake relay(Ry504), convection relay(Ry505) will be on-off
working by mi-com signal after DLB relay is worked.
(Broil relay : It will not be problem with reversing the order in inserting Brown)
(Bake relay : It will not be problem with reversing the order in inserting Blue)
IC102
This is to supply DC 12V with main PCB by voltage regulator.
