Maintenance Service and Trouble Shooting

dissipation make the compressor running without stop. F. Electric leakage of refrigerator

1) Slight electric leakage

Electric insulation has deteriorated due to being affected with damp, thus resulting in slight electric leakage.

2) Serious electric leakage

Refrigerator case has become live due to faults occurred in some electric devices or the erroneous wiring in installing power cord plug or outlet by the user. This is very dangerous.

3)Electric leakage test a) Slight electric leakage

A tingle sense will be experienced as soon as you touch the metal parts

of the refrigerator with your 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 is no problem ,turn off the refrigerator immediately ,then check the insulation of electric circuits with an avometer .

b) Serious electric leakage

Never touch the case body of the refrigerator ,its door handle or other metal parts with your hand .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 an avometer ,the reading will be zero (0Ω); in the worst case ,the fuse will be blown .Check the 3-prong outlet to see whether the live wire and the null line are inversely connected ,this makes the ground protection lead-out from the power cord plug being connected to the live wire .Another possibility is that the live wire and null line of the outdoor power supply circuit have been inversely connected accordingly ,this makes the null line become a live wire .

G .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 laying of tubes or the loosening of parts may cause vibration and noise .
