Diagnosing problems on auto air conditioning systems that
use variable displacement compressors can be difficult. No cooling problems
can be caused by a failure of just the control
valve, the compressor itself or one of
the other system components. So what do you
replace first? You don't replace anything! Not
at least until you've tested the system properly!
The
complete diagnostic charts provide you everything you
need to test the complete A/C system. In fact, there's actually a
procedure to test for low charge! The truth
is, unless you have the complete and proper diagnostics for systems using
variable displacement compressors, anything else you
do is just a guess! Quit guessing! Get the details you need to
quickly and accurately diagnose any auto A/C
system using today's variable displacement A/C compressors. |

| The
air conditioning diagnostic charts in this A/CE™ eBook manual provide
you everything you need when servicing and diagnosing any auto A/C system
using a variable displacement compressor. (Also see our diagnostic charts
for systems using Conventional or 'Fixed'
Displacement Compressors). The 'trouble tree' charts are
easy to use because they
walk you through the complete diagnosis. Don't
guess about which part to replace; test it!
In
fact, with systems using variable displacement A/C compressors, it's
almost impossible to tell the difference between
a faulty control valve or
faulty compressor. That is, it's almost impossible
unless you can test it! That's why you need
the complete 'trouble tree' diagnostics for both systems!
In
auto air conditioning systems using a variable displacement
compressors, the compressor does not
cycle on and off. Instead, the compressor runs
constantly. The compressor suction of the refrigerant vapor (from
the evaporator) is regulated by the control valve. That
valve will change the displacement or 'stroke'
of the compressor. Therefore, in low heat load conditions, the displacement
of the compressor is reduced. That reduces the amount of low side suction.
On the other hand, when there's high demand, the control valve changes the
displacement of the compressor to 'full stroke', That provides the maximum
cooling performance for the system.
The
problem in diagnosing these A/C systems occurs when there's a high demand
for cooling performance, but the system isn't operating
properly. Is it the compressor not pumping?
Is it a low refrigerant charge? Is it just a
faulty control valve? You can't tell unless
you can test them. That's why you need the complete set of diagnostic charts
for all auto air conditioning systems using variable displacement compressors.
Test the system and it's components; then fix it!
It's just that simple when you have all the
right information! |
All WIZ Chart™
A/C Diagnostic Charts are
full color and printable! |
| That's
right! Our A/CE™ Manuals are digital eBooks, but like
all of our WIZ Charts™, the A/C System
Specific Diagnostic Charts are printable! (pdf
file format) You will always have a hard copy to refer to!
Each A/C system Configuration is formatted on
a 2 page chart that includes the schematic
illustration of the system too! (All 5 charts are 10 printed
pages) Every schematic illustration includes
refrigerant flow and clearly details the
high and low sides and the
liquid and vapor sides of each system! You're
never left wondering when you've got WIZ Charts™ A/C System Diagnostics!
