About three weeks ago, I bought a new Kenmore bottom freezer refrigerator
(built by Amana-Maytag). Overall the compressor is quiet, compared to older
units. But when the compressor first comes on, perhaps 30 seconds or so
later, I hear some popping noises that go away about 10 seconds later. This
is loud enough to be heard in the next room (when the TV is off). At times,
it is louder than at other times with no pattern I can figure out. Sears
says this is normal, but I wonder whether it might indicate a problem. Any
thoughts? Thanks.
