I've been reading a lot of reports about the RFG297 and I haven't seen any reports of that particular type of noise. (That's the exact Sumsung model that I've been seriously considering.)

Since it's still under warranty you might want to contact Samsung to see if they have any suggestions. If you purchased it from a retail outfit like Sears you might want to contact them first.

Could you still exchange the unit if it turned out you simply got a bad unit?

I have had this fridge for a month and have not heard this problem. I do remember reading something in the manual about being sure not to block air intake holes in the back of it, especially with plastic bags. Have you checked this out?

It really is so quiet compared to my old Kitchenaid that I can't tell if it is running. Except for the ice, which is no louder than the KA was, so no problem for me there.

I think this is the one I have, too, have had it about a month. Except for a noise when the ice drops, mine also doesn't make any sounds at all. So, something's up-- I would just call and have someone out to look at it.
