Control Boards & PCBs

(Showing 24 of 24)

Shop Mitsubishi Electric control boards & pcbs used for ductless-system logic, communication, inverter, display, and equipment-control functions. This category organizes existing OEM replacement parts by service function so buyers can narrow the catalog without relying on broad keyword results. Always order by the exact manufacturer part number whenever possible. Before purchasing, match the exact PCB number, revision, connectors, indoor or outdoor application, and equipment model. Similar-looking parts may have different ratings, connectors, revisions, dimensions, or approved equipment applications.

Buyer Guide

Start with the equipment model and serial information, then compare the original label and OEM part number. For control boards & pcbs, match the exact PCB number, revision, connectors, indoor or outdoor application, and equipment model. If the original number is superseded, confirm the replacement through current manufacturer documentation rather than assuming compatibility from appearance.

Buyer Guide & FAQs

Can a ductless PCB be selected from appearance?

No. Firmware, communication role, revision, connectors, and indoor or outdoor application can differ.

What information should I provide for fitment help?

Provide the equipment manufacturer, complete model and serial information, the original part number, and clear photos of the label and connections. HVACProSales can help identify options, but final diagnosis and installation should be completed by a qualified technician when appropriate.
