A 1997 GE refrigerator, 20.6 cf, model # TBX21C1, frost free,
ice maker, and it works perfectly, and very quietly... until the
compressor shuts off, then it sounds like you put a handful
a handful of marbles into a metal coffee can, and shook it.
Sometimes its VERY loud, other times not so much. The
rattle sound volume is totally random.

My GE (circa 1999) doesn't make exactly the same noise, but I hear a rather
frightening sound when the compressor shuts off.

I live in the Pacific Northwest, and never turn on the heat. This sound is
loudest and occurs most often during cold weather.

Does anyone know if it portends something disastrous? I've been hearing for
years.
