Leakage Detection
Observe the discharging point of the refrigerant, which may be in the oil discharging part of the compressor and in a hole
in the evaporator.
Check if compressor

REMARKS
• Refrigerant level is low due
• to a leak.
• Normal cooling is possible by
• restoring the normal amount of
• refrigerant and repairing the leak.
• No discharging of Refrigerant.
• Normal cooling is possible by
• restoring the normal amount of
• refrigerant and repairing the leak.
• Normal discharging of the
• refrigerant.
• The capillary tube is faulty.
• Normal discharging of the
Refrigerant.
• Cooling operation restarts
when heating the inlet of the
capillary tube.
• Low pressure at high side
of compressor due to low
refrigerant level.
• No pressure in the high
pressure part of the
compressor.
Check if oil
leaks.
None or too much
YES
Gas leakage.
(Find the leak and repair it)
