Shop furnace control boards and HVAC control boards for residential and commercial heating and cooling equipment. MasterBuilder Mercantile carries OEM and replacement control boards for furnaces, unit heaters, boilers and other compatible HVAC equipment from leading manufacturers.
HVAC control boards manage important equipment functions including ignition, blower operation, safety circuits and the sequence of operation. Because control boards are equipment-specific, replacement boards should be selected using the original part number and equipment model whenever possible.
Furnace Control Boards
Furnace control boards coordinate the operating sequence of compatible gas furnaces and heating equipment. Depending on the system, the board may control ignition, gas valve operation, blower timing, safety circuits and communication between other furnace components.
When replacing a furnace control board, verify the original manufacturer part number and furnace model before ordering. Boards that appear similar may use different wiring, timing, electrical specifications or operating logic.
HVAC Control Boards & Circuit Boards
HVAC equipment uses electronic control boards and circuit boards to manage a variety of electrical and mechanical functions. MasterBuilder Mercantile carries replacement boards for compatible heating, cooling and ventilation equipment in both OEM and approved replacement configurations.
Search by the part number printed on the existing board whenever available. This is generally more reliable than identifying a replacement based on appearance alone.
Unit Heater Control Boards
Commercial and garage unit heaters use control boards and ignition controls to manage burner operation, airflow and safety functions. Our selection includes replacement control boards for compatible unit heaters from manufacturers including Beacon Morris and Sterling HVAC.
MasterBuilder Mercantile carries Beacon Morris control boards and related replacement components for compatible unit heaters and commercial heating equipment.

collection to find replacement components by Sterling part number and heater model.
OEM & Replacement HVAC Control Boards
This collection includes both OEM control boards and replacement boards intended for compatible HVAC equipment. Manufacturers may revise or supersede control boards over time, meaning a current replacement may have a different appearance or part number from the original board.
When a board has been superseded, review the current manufacturer replacement information, wiring requirements and equipment compatibility before installation.
Finding the Correct Furnace Control Board
The most reliable way to identify a replacement control board is to locate the manufacturer part number printed on the existing board and confirm the model information from the furnace or HVAC equipment.
Search this collection using the control board part number, equipment manufacturer or model. Before ordering, verify voltage, connections, wiring configuration and equipment compatibility using the manufacturer's technical information.
