Analysis of Trouble
Leakage of refrigerant and clogging in a refrigerating system will directly affect its
refrigerating capacity. Due to the reduction in its refrigerating capacity, the refrigerator
temperature cannot reach its rated value. The thermostat will not work, thus the
compressor runs continuously. When the evaporation temperature in the system is too high,
the temperature sensing agent in the temperature sensor is also hotter therefore, 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.
d) 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 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
ii) 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
