Explatin of the function of primary parts .
CN01
This is to supply power with primary on Low voltage transformer, and AC120V with main PCB through
harness .
CN02
This is connector which is connected with Door plunger switch and Door lock switch .
(COM-NO)
CN03
This is connector which is connected with oven sensor .
CN04
This is to stop operating self-cleaning and steam mode if hot indicator lamp on cooktop is lighted with
being supplied with AC120V(L1, N) .
CN05
This is consisted of 15 pin and take a role of getting a cable on keypad to connect with touch PCB .
CN06
This is connector which have door lock motor, cooktop warming center, and relay of oven lamp
connected .
Ry-source relay(Ry01) Circuit is designed to all relay worked after Ry-source ralay is being worked . (For safety)
DLB relay(Ry02)
Circuit is designed to have broil relay or worked after DLB relay is being worked by Double line break .
Broil relay(Ry03),
Bake relay(Ry04)
Broil relay(Ry03), Bake relay(Ry04), will be on-off working by micom signal after DLB relay is worked .
(Broil relay : It will not be problem with reversing the order in insering Black and Brown)
(Bake relay : It will not be problem with reversing the order in insering Yellow and Gray)
ZNR1
This is the element to protect main PCB, if over voltage is supplied with PCB .
IC02
This is to supply DC12V with main PCB by voltage regulator .
IC03
This is to supply DC5V with main PCB by voltage regulator .
W/Drawer Relay(Ry06)
and T02
This is terminal to connect harness with relay to get heater on warming drawer work (some model)
T01 terminal
This is the terminal to supply L1 voltage(120V) with warming drawer relay(Ry06), convection relay(Ry05)
(some model)
