INTRODUCTION

This table lists all the common malfunctions that you may find with your equipment. Perform

the tests, inspections, and corrective actions in the order they appear in the table.

This table cannot list all the malfunctions that may occur, all the tests and inspections needed to

find the fault, or all the corrective actions needed to correct the fault. If the equipment

malfunction is not listed or actions listed do not correct the fault, notify your supervisor.

Troubleshooting by unit maintenance is limited to checking operation of the air conditioner.

Any failure in performance or suspected problem, other than those described in WP0010 should

be reported to direct support maintenance.

The malfunction/symptom index (WP0009) is a quick reference index for finding

troubleshooting procedures. Associated with each symptom name is a work package sequence

number representing the starting point in a troubleshooting sequence. Should any one symptom

require more than one troubleshooting sequence to arrive at the most likely area of investigation,

the additional starting point numbers are presented.

As the troubleshooting activity progresses through to the conclusion of a particular sequence, a

reference is made to the next logical troubleshooting sequence by work package sequence

number or by referring to the malfunction/symptom index to locate the next failure symptom

work package. This type of activity continues until successful fault isolation is achieved.
