a. Troubleshooting at the unit maintenance level requires location of any trouble as quickly as possible. Once
the trouble is located, repair or replace the item if authorized by the Maintenance Allocation Chart. This
section is designed to aid in quick, accurate diagnosis of problems associated with the ROWPU. In its
simplest state, troubleshooting the ROWPU is an exercise in logic.
b. It is most important to understand that the ROWPU is really made up of a series of systems with each
system having a number of assemblies. Some of these systems are interrelated; others are not. The
ROWPU operates within a framework of understanding of all the systems and their assemblies.
NOTE
Before using the troubleshooting table, check your work order
and talk to the operator, if possible, for a description of the
symptoms and the steps that have been taken to correct them.
c.
This section breaks the ROWPU down into its systems and assemblies, allowing the problem to be isolated.
The troubleshooting table lists the most common problems and the most probable causes of trouble. It
would be impossible to list every possible problem that could happen along with every possible cause, but it
will locate most problems and eliminate a lot of unnecessary guesswork. The systematic format will locate
problems within a given assembly but, because many of the ROWPU assemblies are interrelated, the
solution to a particular problem may be found in more than one assembly.
