4. Inspection method
To find the sources of noise, press the vibration spot with your hand while the refrigerator is in
operation and listen attentively whether the vibration becomes weaker or vanishes. If the
refrigerator has not been levelly placed, put a level meter on its top table and adjust the leveling
screws on its legs. In case noise occurs from the compressor, strike different locations on the side
surface of its case using a rubber hammer or hand hammer with a wood block in between to
determine whether the suspended springs are out of balance or being seized.
