TROUBLE SHOOTING

In diagnosing common faults in the air conditioning system, it is useful to present
the logical pattern of thought that is used by experienced technicians. The charts
which follow are not intended to be an answer to all problems, but only to guide
your thinking as you attempt to decide on your course of action. Through a series of
yes and no answers, you will follow the logical path to a likely conclusion.
Use these charts as you would a road map, if you are a beginning technician. As
you gain experience, you will learn where to establish the shortcuts. Remember
that the chart will help clarify the logical path to the problem.
