Diagnosing
Auto A/C Systems: This section is focussed on understanding and interpreting
the pressure gauge readings. That's because anybody can read the numbers
on the gauges... but diagnosis starts with the
interpretation of those readings. What
are 'normal' readings? Are the gauge readings correct for this system? What
should they be? The diagnosis has to start with understanding what the gauge
readings should be... then determining what the problem is. |
|
Typical
Gauge Readings Defined:
This
section starts by providing the details of what the typical or normal gauge
readings are for each of the system designs (Expansion Valve; CCOT; TXV and
Cycling Clutch; Variable rate and EPR valve systems). Therefore understanding
what a proper operating system should be. Understanding the proper gauge
readings provides the basis for understanding the problem
gauge readings.
Interpretation
of the gauges:
Understand
what the gauge readings are really telling you.
High pressures generally indicate problems with overcharge or poor cooling
problems while excessively low pressures point to system leaks, low charge
and problems with refrigerant flow through the system. Each of these conditions
are reviewed in detail.
Universal
Diagnosis Chart:
All
of the gauge reading combinations are explained in this excellent
Universal A/C Diagnosis Chart. For each of the
gauge reading combinations, we've provided all the possible troubleshooting
procedures. That helps save time and money
immediately! As an example, consider the problem gauge readings of
having the high pressures are too low and low pressures are
too high. The chart details the diagnosis towards compressor failures,
inoperative clutch problems and internal valve problems. Each of them including
explanations of the problem area.
Troubleshooting
Details:
For
each of the problem gauge reading combinations in the Universal Diagnostic
Chart, illustrated and detailed troubleshooting and
diagnostic procedures are provided. They pin point and detail the
problem areas and provide important notes and cautions that have to be
considered. Repair processes are outlined along with Tips
and Tricks used by the professional A/C technicians.
