DAEWOO V–121 BL4
SYMPTOM DIAGNOSIS
PRESSURE TEST CHART (R–134A SYSTEM)
Test ResultsRelated SymptiomsProbable CauseRemedy
Discharge (high)
pressure abnormally
highAfter stopping the compres-
sor, the pressure drops
about 299 kPa (28 psig)
quickly, then falls gradually.Air in the system.Recover, evacuate and re-
charge the system with the
specified amount of refrig-
erant.
The condenser is exces-
sively hot.Excessive refrigerant in the sys-
tem.Recover, evacuate and re-
charge the system with the
specified amount of refrig-
erant.
Reduced or no airflow
through the condenser.Condenser or the radiator fins are
clogged.Clean the condenser or the
radiator fins.
Condenser or the radiator fan is
not working properly.Check the voltage and the
fan rpm.
Check the fan direction.
Line to the condenser is ex-
cessively hot.Restricted flow of refrigerant in
the system.Locate and repair the re-
striction.
Discharge pressure
abnormally lowThe condenser is not hot.Insufficient refrigerant in the sys-
tem.Check the system for a
leak.
Charge the system.
High and low pressures are
balanced soon after stop-
ping the compressor.Faulty compressor pressure relief
valve.Repair or replace the com-
pressor.
Low–side pressure is high-
er than normal.Faulty compressor seal.
The outlet of the expansion
valve is not frosted.Faulty expansion valve.Replace the expansion
valve.
Low pressure gauge indi-
cates vacuum.Moisture in the system.Recover, evacuate, and re-
charge the system.
Suction (low) pres-
sure abnormally lowCondenser is not hot.Insufficient refrigerant in the sys-
tem.Repair the leaks.
Recover, evacuate, and re-
charge the system.
The expansion valve is not
frosted and the lowpressure
line is not cold.Faulty expansion valve.Replace the expansion
valve.
Low–Pressure gauge indi-
cates a vacuum.Frozen expansion valve.
Discharge temperature is
low and the airflow from the
vents is restricted.Evaporator is frozen.Clear the restricted evapo-
rator case drain.
The expansion valve is
frosted.Expansion valve is clogged.Clean or replace the expan-
sion valve.
The receiver–dryer outlet is
cool and the inlet is warm.Receiver–dryer is clogged.Replace the receiver–dryer.
Suction pressure ab-
normally highLow–pressure hose and
check joint are cooler than
the temperature around the
evaporator.Expansion valve is opened for too
long.Replace the expansion
valve.
Capillary tube is loose.
