SECTION 2. MAINTENANCE

This section provides procedures for the testing and replacement
of the various parts used within the cabinet. Before replacing any
parts, refer to the Troubleshooting Section. It will aid you in deter-
mining the cause of the malfunction.
You may use two test instruments to check the electric
components.
1. A continuity light
2. An ohmmeter
When the manual refers to the circuit being closed, the continuity
light illuminates or the ohmmeter reads zero unless otherwise noted.
When the manual refers to the circuit being open, the continuity
light will not illuminate or the ohmmeter will read 1 (one) or
infinite resistance.
A continuity tester cannot be used to check coils.
In most procedures of the maintenance section, the access panel
must be removed from the top of the module. This access panel
can easily be removed by taking out the four screws that fasten it
to the module shell.
If the component module of the cabinet has to be removed,
be sure to remove the four screws (one at each corner) before
lifting it from the unit. Also, when work has been completed
on the module, be sure to relocate it properly and reinstall the
screws that fasten the module to the cabinet. Failure to do so
might cause the unit to perform inadequately.
