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  



Clean.

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.

Suction and 
discharge 

Reduced airflow through A/C
