Does a refrigerator compressor have reed valves? is there a a check valve in the freon line?
10 year old kenmore top freezer refrigerator began making annoying noise from compressor about a month ago. cooling properly, exterior compressor mounts are fine. coils clean, defrost timer working properly, defrost cycle working properly.the noise sounds like a valve-type internal clatter, am not sure of compressor RPM but extimate the noise is several hundred cycles per minute. when compressor starts, the noise is not there but after a couple of minutes (maybe after the freon pressure builds), the noise is annoyingly loud.
so the question: is this a valve problem? i've never had this happen on any other refrigerator we've ever owned.
