11-3 REFRIGERATION CYCLE
▼ Troubleshooting Chart
PARTIAL
LEAKAGE Freezer
compartment and
Refrigerator don't
cool normally. Low flowing sound of
Refrigerant is heard
and frost forms in
inlet only. A little higher than
ambient
temperature. • Refrigerant level is low due
to a leak.
• Normal cooling is possible by
restoring the normal amount
of refrigerant and repairing
the leak.
COMPLETE
LEAKAGE Freezer
compartment and
Refrigerator don't
cool normally. Flowing sound of
refrigerant is not
heard and frost isn't
formed. Equal to ambient
temperature. • No discharging of
Refrigerant.
• Normal cooling is possible by
restoring the normal amount
of refrigerant and repairing
the leak.

PARTIAL
CLOG Freezer
compartment and
Refrigerator don't
cool normally. Flowing sound of
refrigerant is heard
and frost forms in
inlet only. A little higher than
ambient
temperature. • Normal discharging of the
refrigerant.
• The capillary tube is faulty.

MOISTURE CLOG Cooling operation
stops periodically. Flowing sound of
refrigerant is not
heard and frost melts. Lower than ambient
temperature. • Cooling operation restarts
when heating the inlet of the
capillary tube.

COMP-
RESSION Freezer and
Refrigerator don't
cool. Low flowing sound of
refrigerant is heard
and frost forms in
inlet only. A little higher than
ambient
temperature. • Low pressure at high side of
compressor due to low
refrigerant level.
NO COMP-
RESSION No compressing
operation. Flowing sound of
refrigerant is not
heard and there is
no frost. Equal to ambient
temperature. • No pressure in the high
pressure part of the
compressor.

11-3-1 Cleaning
There is no need for routine condenser cleaning in normal Home operating environments. If the environment is
particularly greasy or dusty, or there is significant pet traffic in the home, the condenser should be cleaned
every 2 to 3 months to ensure maximum efficiency.
If you need to clean the condenser:
●
Remove the mechanical cover.
●
Use a vacuum cleaner with a soft brush to clean the grille, the open areas behind the grille and the front
surface area of the condenser.
●
Replace the mechanical cover.
