Is the plug being
inserted?
Yes
No
Is the voltage over
99V?
Is the geographical environment being
Yes
No
Is the compressor
operating?
Short the overload protector and see if
Yes
Inspection of the frosted cooler
Non defrost
Inspection of freon leakage
No freon leakage
Defective freon circuit
The lower pressure tube of
compressor fails to such the air.
VII. FAILURE DIAGNOSIS
Insert the power plug.
Any shutdown? Check the abnormal
power cord or switch
Is a special socket used by the
refrigerator?
Yes
using a special one?
Short the F thermostat and see if the
compressor is operating.
Not operated
When regulat e D meter to cooling
operation side, is the compressor
operation?
* Turn D time to right side
till heating two noises
Non-operating
the compressor is operation.
Non-operating
Is the relay of PTC starter normal?
Yes
Is the capacitor normal at starting or
operating?
Yes
The contacting point being poor?
No
Is the circuit of compressor coil
normal?
Ice beads or serious frost formed
in the cooler chamer
Check the leakage
location
Freon circuit
clogged
No
Is a socket affected by other electrical wiring?
Operating
Change F-THM, then check is it due to the freon leakage of thermo
sensor or by poor contacting point?
Operating
Is the temperature fuse
melted?
Engaged
Is temperature switch
engaged?
Engaged
Operating
Abnormal
Abnormal
Yes
Abnormal
Poorly
defrosted
Freon leakage
Clogged by impurities
Poor compression of
the compressor
No
Replace the temperature fuse
No
Replace the temperature
switch
Replace D meter.
Replace the overload
protector.
Replace the relay of PTC
starter.
*Impedance short (0Ω) and poor circuit (0∞)
Replace the capacitor.
*In case of the normal item, the needle of the
panel will become (∞Ω) after one vibration.
Repair the contacting point.
* Remove the pin from the connecting point and
check if it has turned into black.
Replace the compressor and
drying filter.
* Check the circuit of mail coil, auxiliary coil
and resistance value.
Refer to the mothod of non-
defrost
Poor location be repaired.
Replace the compressorm
drying filter. Clean the freon
circuits.
* When the inner side of compressor is too dirty,
it must be replaced.
Replace the clogged parts.
Replace the drying filter.
Clean the freon circuit
Replace the compressor,
drying filter. Clean the freon
circuit.
