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.
D) No Stoppage Of Compressor Due To Damaged Heat-Insulation Layer Inside Case Body
And / Or Door Seal
Analysis of Problem
When the heat-insulation layer inside the case body deteriorates or the door seal does
not closely touch the doorframe, the temperature in the refrigerator will rise and
makes the compressor run continuously.
Remedy
Check the heat-insulation layer for damaged parts. Repair it if damaged 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.
e) Too much food is placed in the refrigerator, or is placed too densely, resulting in poor
ventilation or poor conditions for temperature sensing hence no stoppage of the
compressor.
f) Too high ambient temperature, poorer ventilation and heat dissipation make the
compressor run without stopping.
Electric Leakage Of Refrigerator
a) Slight Electric Leakage
Electric insulation has deteriorated due to being affected with damp, thus resulting in
slight electric leakage.
b) 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.
c) Electric Leakage Test
i)
Slight Electric Leakage
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.
ii)
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 (0
Ω
); in the worse
