Frick Parts
LSI Controls maintains comprehensive support of control components for the Frick line of refrigeration compressors. We were the original designers and manufacturers of these control systems with over 15,000 microprocessor controls delivered. All components are manufactured to the highest level of quality and subjected to complete testing and quality control procedures. Many parts are available as Remanufactured or New depending on your needs.
Control Boards
All of our control boards are backwards compatible. If you have a Revision A or B board, you will need to purchase both the input and output modules in addition to the board. If you need installation instructions for the board, we have them for the RWB II (PDF) and RXB (PDF). Note that Frick has multiple part numbers for some of these boards, so if you do not see your board listed call us to inquire. Contact us if you are interested in a board repair (flat rate: $500).
LCD Displays
The RWB II and RXB/RDB displays are now available in two formats. The “Original” contains the standard display (see bottom screen in comparison), while the “Economy” model (top screen in comparison) comes with a smaller and less expensive screen pre-mounted to a bracket to fit the same space. Note that all of our displays come with the cable needed to connect to the control board.
