Test results

Related symptoms

Probable cause

Remedy

Discharge
(high) pressure
abnormally high

After stopping A/C
compressor, pressure drops
about 196 kPa (2.0 kgf/cm

2

,

28 psi) quickly, and then falls
gradually.

Air in system

Recover, evacuate (see SYSTEM
EVACUATION ), and recharge
with specified amount (see
SYSTEM CHARGING ).

Reduced or no airflow

Clogged A/C
condenser or
radiator fins

through A/C condenser.



A/C condenser
or radiator fan
not working
properly



Check voltage and fan rpm.



Check fan direction.

Line to A/C condenser is
excessively hot.

Restricted flow of
refrigerant in system

Restricted lines.

Discharge
pressure
abnormally low

High and low-pressures are
balanced soon after stopping
A/C compressor. Low side is
higher than normal.



Faulty A/C
compressor
discharge valve



Faulty A/C
compressor seal

Replace the A/C compressor.

Outlet of expansion valve is
not frosted, low-pressure
gauge indicates vacuum.



Faulty expansion
valve



Moisture in
system



Replace.



Recover, evacuate, and
recharge with specified
amount.

Suction (low)
pressure
abnormally low

Expansion valve is not
frosted, and low-pressure line
is not cold. Low-pressure
gauge indicates vacuum.



Frozen
expansion valve
(Moisture in
system)



Faulty expansion
valve



Recover, evacuate, and
recharge with specified
amount.



Replace the expansion
valve.

Discharge temperature is low,
and the airflow from vents is
restricted.

Frozen evaporator

Run the fan with A/C compressor
off, then check evaporator
temperature sensor.

Expansion valve is frosted.

Clogged expansion
valve

Clean or replace.

Suction pressure
abnormally high

Low-pressure hose and check
joint are cooler than the
temperature around
evaporator.

Expansion valve open
too long

Repair or replace.

Suction pressure is lowered
when A/C condenser is
cooled by water.

Excessive refrigerant
in system

Recover, evacuate, and recharge
with specified amount.

High and low-pressures are
equalized as soon as the A/C
compressor is stopped, and
both gauges fluctuate while
running.



Faulty gasket



Faulty high-
pressure valve



Foreign particle
stuck in high-
pressure valve

Replace the A/C compressor.
