Control Boards

HVAC control boards manage system operation by coordinating ignition, blower operation, safety circuits, and fault monitoring in furnaces and air handlers. NWF Supply stocks a range of OEM and OEM replacement control boards compatible with major HVAC manufacturers including Nordyne, Lennox, Frigidaire, Carrier, and York.

These control boards are used in residential and light commercial furnaces and air handlers to regulate heating cycles, blower timing, limit switches, and diagnostic functions. All replacement boards are selected to meet original equipment specifications for voltage, ignition type, connector layout, and system compatibility, ensuring proper operation and reliable performance.

Our inventory includes direct-replacement HVAC control boards designed for accurate system control, straightforward installation, and long-term reliability in demanding HVAC environments.
