That MAY be true, but maybe not.  The internal wiring can be an antenna 
that radiates the trash, but the  power line can be a better one. The 
first thing I would try (because it's easy and inexpensive) would be a 
ferrite choke wound with multiple turns on the power cord to the 
refrigerator. Use as many turns as you can, or study the graphs in my 
RFI tutorial for guidance as to the number of turns.


Another thing to check -- look at the wiring (or have an electrician 
look at it)  between the outlet where it's plugged in and the breaker 
panel. Is the third wire (the ground) connected all the way through?  It 
MUST be, by law, and if it's missing, could make things worse.

BTW -- this is the first RFI report I've seen from a product of a major 
Korean company.  If you can't fix it with a choke, I'd go back to the 
mfr and ask for a fix.
