Control Boards

HVAC Control Boards

The HVAC Control Boards category focuses on the electronic “brain” of furnaces, air handlers, rooftop units and heat pumps. These boards coordinate blower operation, ignition, safety circuits, staging, timing, and communication with thermostats. A correct replacement board restores stable operation, eliminates nuisance lockouts, and protects compressors, inducer motors and blowers from unsafe conditions. This section is designed for technicians who want the right OEM or universal control board matched to the exact equipment and application.

Here you’ll find integrated furnace control (IFC) boards, air-handler blower boards, fan control centers, ignition control modules, defrost interface boards, and universal retrofit controls. Many options include LED diagnostics, dip-switch configuration, fan delay settings, dehumidification terminals, and low-voltage terminal strips that streamline wiring and troubleshooting. For modern communicating systems, select boards that support two-wire communication, fault code storage, airflow profiles and staging logic as required by the OEM design.

• Integrated furnace control boards (IFC) for gas furnaces and package units.
• Air handler and blower control boards for PSC and ECM motor platforms.
• Heat pump and outdoor unit interface boards that work with defrost and fan control.
• Ignition and fan control modules for retrofit or OEM-style replacements.
• Universal HVAC control boards with adapter harnesses and configuration guides.

When selecting a control board, do more than match by looks. Confirm OEM part number, board revision, equipment model and serial, voltage, blower type, ignition method, and any special features such as dehumidification, two-stage heat, or communicating control. For universal boards, carefully review cross-reference charts, wiring changes, jumper settings and timing options. Use the Compare tools on this page to review terminal layout, stages supported, diagnostics, and included accessories such as harnesses or mounting hardware.

Pro tip: Before condemning a board, verify line voltage, low-voltage transformer output, polarity, ground, safeties, pressure switches and limit circuits. Record fault codes, photograph existing wiring, and note dip-switch positions. Share those details and we can help you select the correct OEM or universal HVAC control board that will drop in cleanly and minimize callbacks.
