normal state (it may exceed 90 ℃ in case of running for a longer period of time ).
b) After the compressor has operated normally for 5~10 minutes , ouch and feel the condenser ,the
temperature of its upper part should be higher than that of its lower part (or its right part is hotter than
its left part ,depending on the type of condenser coil ),this indicates that the refrigerant is circulating . If
the condenser is not hot ,this means the leakage of refrigerant .In case the condenser radiates heat for
only several minutes and then cool
clogged .As for the forced air cooling condenser ,hot air will be blown out of it
system is out of order .
c) Feel the filter
temperature on the filter's surface should be a little higher than the ambient temperature ;if you touch it
with your hand ,you will have a sense of slight heat .In case dew condensation appears due to the fact
that its temperature is obviously lower than the ambient temperature ,this means that most meshes of
its screen has been clogged ,resulting in an
obstructed flowing of refrigerant ,thus causing a drop in temperature due to throttling .
d) Feel the temperatu re of ex haust gas from the refrigerating system .the exhaust gas should b e
very hot and this is the n ormal working state .For those refrigerator with enclosed type of compressor
refrigerating system, no frost or dew drop
something wrong in the system (Frosting and dew condensation may appear for a very short
period when just st arting the machine ,this is a
combination of several compone nts ,they are re lated and have influence on each other .In
abnormal phenomen on h as been found through the abov e-mentioned ch eckups ,you need not to
make a hasty conclusion based on o nly one abno rmal phenomenon .It is advisable to find out two or
more abnormal phenomenon ,or conduct troubleshooting comprehensively with the aid of instruments
or other ways ,because sever al kinds of troubl es may share a common abnormal ph enomenon ,and
two or more abnormal p henomena may occur simult aneously due to a cert ain trouble .With this
method ,you can reject some suspicious troubles and finally make a correct judgment .
