Armstrong Air Furnace Control Boards

Armstrong Air furnace control boards manage important operating functions within compatible heating systems. Replacement controls may be specific to a furnace model or series, and older controls can sometimes be superseded by newer manufacturer part numbers.

A popular example is the Armstrong Air R40403-003 furnace control board. When replacing a control board, verify the complete manufacturer part number and furnace model rather than selecting a replacement based only on appearance.
