Bought a Kenmore bottom-freezer fridge/freezer last November, and
since the day it was delivered it has made a noise when the compressor
kicks on that sounds like syncopated knocking or popping noises. It
almost sounds like "hard" bubbles popping inside a pressurized plastic
line, if that makes sense.
I had Sears' home service out to look at the unit, and the tech said
it's part of the new (worse) design, something about the way two
plastic lines of differing inside diameters are joined together and
the pressure difference. I specifically asked if this could cause wear
problems down the line with the compressor or other parts of the
cooling system and he said "no".
Not for nothing, but I don't believe the guy. After 40 years of
refrigerators whose only sound is the fan, I have to put up with a
refrigerator that knocks like my car's engine when I forget to put
premium gas in the tank? That's either a crock of poo, or the dumbest
damned design idea.
Is the guy right? Does anyone have experience with new 'fridges making
these noises? Am I going to have to suck it up and put up with hearing
the noise from my bedroom in the middle of the night? Or should I call
a local (reliable) appliance repair place and have them check it out?
