KSRG25FTBT01 Fridge compressor rattle AFTER cooling cycle completed

[aribert]

Greetings:

Not a crisis, Whirlpool KitchenAide fridge works well but the compressor will have a quick rattle/clunk sound minutes after compressor has shut off.  I opened up the rear cardboard access panel and observed the the compressor began to very gently oscillate a minute or two after shut down.  The oscillations increased until a clunk, clunk, clunk sound from the compressor and the compressor oscillation stopped.  Does not happen at every cooling cycle - guessing about 50% of the time.  Compressor mounting (bushings) still feel quite firm.  Compressor does not rock or oscillate on start up or while running.  With a significant amount of force, I can rock the compressor and create a similar, but louder, clunking sound.   Anything to be concerned about or to monitor?

One of the internal motor mount is probably loose or broken.  May or may not last for a long time this way.

Thank you for your response - the sound is definitely internal to the compressor housing.
