A tingle sense will be experienced as soon as you touch the metal parts of the refrigerator with the hand. When you test them with a test pencil, its neon lamp will come on. In that case, the first thing you need to do is to determine whether the grounding is perfect. If the grounding has no problem, turn off the refrigerator immediately, then check the insulation of electric circuits with a voltmeter.

iii)Serious electric leakage

Do not touch the case body of the refrigerator, its door handle or other metal parts with your hand. When you test the refrigerator with a test pencil, it will light up intensively. Measure the resistance between the power cord plug and the case body with a voltmeter, the reading will be zero (0Ω); in the worse case, the fuse will blow. Check the 3-prong outlet to see whether the live wire and the null line are inversely connected. One possibility is that the live wire and null line of the outdoor power supply circuit have been inversely connected; this makes the null line become a live wire.

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 vibrations and noise.

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.
