Symptom
Cause
Suggestions
• The EVAP cools down and warms
again.
• The condenser warms in proportion
as the EVAP cools.
• The process continues to repeat.
Moisture in the refrigerant
causes the malfunction.
Replace the refrigerant
• The condenser is cold.
• The EVAP is not cold.
• The temperature of the compressor
is high.
Foreign substances hamper
the cooling cycle.
Locate the disturbed section
and make repairs
• No difference in temperatures
between suction pipe and discharge
pipe.
• The temperature of the compressor
is maintained at room temperature.
• The EVAP does not cool down.
The compressor is defective
Replace the compressor
• Frost on the suction pipe.
• The condenser is overheated.
• The refrigeration in the EVAP is
not effecient.
Too much refrigerant
Replace the refrigerant
• The condenser is cold.
• The compressor surface
temperature is high.
• The refrigerator is not easily get
cooled.
Refrigerant leaks.
(Slight refrigerant leakage
causes partial cooling with
frost on the EVAP)
After welding the leaked spot,
replace the refrigerant
