how can I find out the model number ?

There appears to be just two electronic components in the parts list - both capacitors which may be bought from any electronics supplier...

Capacitor Aluminium 12 uF 75ºC 10% 250V AC

Capacitor Oil 100 uF 125V AC 35x55mm

And a defrost timer assembly
TIMER-DEFROST;-,110V,50~60Hz,

which will have to come from a specialist spares supplier

The number you quote is the Circuit Diagram

It is not a component - you give no information about the specific component needed - many electronic components can be identified by looking at them.

The Circuit Diagram number appears to be DA68-11029A
The Fridge model number appears to be S38BLCSWCL XAP
