[Avodah] The Heter of Davar She Eino Mischavin by a Star-K Oven

[Elliott Shevin]

I believe it remains an >open Shiala. It seems to me if the oven flame is already lit when the door opens, you have a counterexample that would rule out psik reisha.  Going in the opposite direction, closing the oven door when the flame is lit will hasten the time when it's extinguished. But again, it's a davar sheeino mischavin and, since it's often not lit when you open the door, not a psik reisha.
 
I don't see how the refrigerator is different from the oven, except in one trait 
the Star-K site mentions: the oven will produce a flame, but the refrigerator's 
compressor only produces sparks which might be considered insignificant. 
Otherwise, their operation is the same: opening the door MIGHT hasten the 
startup of the compressor, and closing it MIGHT hasten its shutting down, 
but no psik reisha in either case. 
 
If anything, putting food in the refrigerator is more likely to be hachana, since you 
want to preserve leftovers you won't be eating that day; you're much more likely to 
be consuming what you've left in the oven on the same Shabbos.
 Shabbat shalom! (I waver between "Askenazis" and "Sephardit" too. Sue me. <g>)
