Stronger vibration and loader noise
1. Refrigerator placed improperly
a. Uneven ground
Uneven ground will cause the refrigerator to be placed unsteadily, causing stronger
vibration and noise during its operation.
b. Leveling screws not properly adjusted
If the leveling screws on refrigerator legs have not been adjusted properly, vibration
and noise will still occur even if the refrigerator has been placed on a level ground.
2. Abnormal noise from compressor
Three suspended spring inside the compressor case are out of balance, and strike
against the case, moreover, the wear of compressor parts may cause noise sometimes.
3. Resonance of tubing and loosening of parts
Improper and compact lying of tubes or the loosening of parts may cause Vibration
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.
