the resistance between the power cord plug and the case body with an avometer ,the
reading will be zero (0W); 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 there frigerator 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 .
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 weake 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 so as to determine whether
the suspended springs are out of balance or being seized .
the thermostat is unable to cut off the power supply to the compressor and stop it.
Remedy If it has been found that the refrigerant in the system is insufficient in quantity,
recharge it with refrigerant. In case clogging occurs, disassemble the part where it
is blocked. If the evaporation temperature is too high, settle this problem with an
appropriate quantity of refrigerant.
3) No stoppage of compressor due to damaged heat-insulation layer inside case body
and/or door seal Analysis of Trouble When the heat-insulation layer inside the case body
deteriorates or the door seal is not closely touches the door frame, the temperature
in the refrigerator will rise and makes the compressor running continuously. Remedy
Check the heat-insulation layer for its damaged parts, repair it to improve its heat-
insulation property. If the door has deformed or the door seal is not tightly sealed
against the case body, repair them, respectively.
5) Too much food is placed in the refrigerator, or is placed too densely, resulting in poor
ventilation or poor conditions for temperature sensing, and hence no stoppage of the
compressor.
6) Too high ambient temperature, poorer ventilation and heat 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
