C. Double Check Before Disassembly
The source of most compressor troubles can be traced not to one component alone, but to the
relationship of one component with another. Too often, a compressor can be partially
disassembled in search of the cause of a certain trouble and all evidence is destroyed during
disassembly. Check again to be sure an easy solution to the problem has not been
overlooked.
D. Find and Correct Basic Cause
After a mechanical failure has been corrected, be sure to locate and correct the cause of the
trouble so the same failure will not be repeated. A complaint of “premature breakdown” may
be corrected by repairing any improper wiring connections, but something caused the
defective wiring. The cause may be excessive vibration.
