    Possible reasons for a Compressor Crank Shaft break

    Recently we inspected a compressor (under warranty) with vibration and loud noise. Upon opening we found that the crank shaft is completely broken into two pieces.

    But surprisingly there is no damage or even a scratch on the cylinders/piston. What could be the reason? Is it a manufacturing defect?

    Application : Dairy Cold Room Chiller
    Condensing Unit : Carrier CRL400 CX (Air Cooled)
    Compressor : Bitzer 2 CES 4 (Semi Hermetic)
    Refrigerant : R22
    Operation Time before failure : 3 months
