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 Proper
ventilation and heat
Dissipation make the compressor running without stop
F. Electric Leakage of regrigerator
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 Voltmeter
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 Volt meter ,the reading will be zero (0%); in the
worst case ,the fuse will be blown .Check the 3-prong outlet to see whether
the live wire and the Neutral wire 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 & Neutral wire of the outdoor
power supply circuit have been inversely connected accordingly ,this
makes the Neutral wire 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
