Measure ambient air temperature 16-18" in front of the condenser. Measure air temperature
of the AC duct closest to the evaporator using the vent probe. The temperature difference
between ambient and duct air should be approximately 30°F (-1°C) in a properly
performing system.
Less than 30°F (-1°C)
CHECK FOR OUTSIDE HEAT ENTERING CABIN
Blend air door not closing
Heater valve not closing
Fresh air door not closing
CHECK EVAPORATOR CONDITION
Evaporator fins dirty or restricted
Evaporator interior coated with scale
Air bypassing evaporator (missing gaskets)
Inadequate airflow across evaporator (i.e.,
clogged cabin air filter or rodent infestation
can also damage compressor slugging
failure)
CHECK REFRIGERANT AND OIL CHARGE
SERVICE
Was system evacuated?
Was system cleaned?
Was the compressor oil level checked?
Refer to diagnostic chart C
Repair & Retest as Necessary
Greater than 30°F (-1°C)
System performing to specifications
Check temperature balance at condenser
(see Chart A)
