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.
