Troubleshooting and Replacement Parts

 

In order to properly service and troubleshoot the subject system as well as identify the correct replacement part for your aircraft, it is important to determine the type of system installed in your aircraft. ACC supports the installations for JB Air, Parker Airborne and Keith Products systems.  You can determine if a Keith Air Comm system is installed in your aircraft in one or more of the following ways:

  • Check the logbook

  • Locate a major component (compressor, condenser or evaporator)

    • The components should have a placard that identifies Keith Products, JB Systems or Parker Airborne Air Conditioning. If the placard does not identify one of these manufacturers, your system may not be an ACC installation and the parts list will not be appropriate for your aircraft.

  • Contact us if you have any doubts about your system configuration. A digital picture of the failed component e-mailed to us will expedite this process. We will respond with part number, availability and price.

Further it is important to have the proper equipment and know the configuration of the system installed in your aircraft. Locate and access the compressor, condenser, all evaporator(s), receiver-dryer bottle and charging ports.
It is important to have a good concept of the dynamic nature of a vapor cycle system. Before you begin, it is advisable to print and review the troubleshooting principles manual.
