Manual Diagnostic Menu

The Manual Diagnostic menu, shown in Figure 52, is used for troubleshooting and testing the system on a component basis. It
allows the service technician to turn individual components of the system on and off for troubleshooting purposes. Pressing
the BACK button returns the display to the Main menu and turns off all the active loads.
This screen should only be used by qualified technicians to troubleshoot the system.
The items shown in Table 49 are for the first barrel in the unit only. The list includes additional components with their related
barrel number, i.e. Hot Gas Sol #2, etc.

The compressor can suffer damage if it is allowed to run without either a hot gas defrost or liquid line solenoid open. The
software is designed to turn on the hot gas solenoid for a barrel to prevent damage from occurring.
