Compressor Noise

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.

From the discussion on air compressors in this group, it sounds like it is unloading the pressure off the compressor, so it doesn't have to start under full load.
So I'd agree that it is normal, if annoying.

Ross,
I'd bet on the evaporator 'popping' that often happens on these with expansion/contraction of the aluminum. Loosening the evaporator mounting screws - when screws are used - has helped with this a little. We had a run of these on the Whirlpool BF's (also made by Amana) a few years ago, and loosening the screws 1/4 to 1/2 turn corrected the noise complaints.
When it starts, hold the freezer door open and see if the 'pops' seem to be coming from inside the freezer compartment.
If it doesn't get any worse, I'd probably not worry about it too much. But if it continues to be an annoyance, I'd suggest that a warranty company loosen the evap and/or evap cover screws a bit - will be worth a try.
Another possibility is the compressor itself. They're being made in Brazil by Embraco, and have had more than their share of problems. The good news is they're covered under a 5 year warranty.
Hope that helps.
God bless,
