Can some one more capable than me & the dumb shop assistants help me please. I think there are two basic types of fridge freezers but need it confirmed :-
1 - Uses a split circuit that allows refrigerant to chill freeze the freezer comp & another up the back of the fridge to chill this compartment.
2 - All of the refrigerant cycle is in the freezer compartment & air is then ducted via a fan & regulator into the fridge compartment.

Am I close??
