A refrigerator that’s suddenly noisier than normal is telling you something specific, and the type of noise is a genuinely useful clue before a technician even arrives.
Clicking
Repeated clicking, especially if the unit doesn’t seem to actually start cooling afterward, often points to a compressor start-relay issue rather than the compressor itself.
Buzzing or Humming
A steady buzz can be normal compressor operation, but a noticeably louder or new buzzing sound is worth having checked, particularly alongside a compressor that seems to run longer than usual — the kind of excessive-runtime pattern documented as 40/1/40 on Classic Built-In units.
Rattling
Rattling is more often a loose panel or a fan blade catching on debris than a serious refrigeration problem — genuinely one of the more affordable things we check for.
