Fasco 50DK406816U62B1NSMP Inducer Motor Assembly

Carrier’s OEM Fasco 50DK406816 Inducer Motor Assembly is a dual‑voltage draft inducer motor used in gas‑fired furnaces to establish the venting flow and support safe combustion. It is a 1/16‑hp motor designed for 400/460 V operation at 50/60 Hz, with typical current draw around 0.20 A at 400 V and 0.26 A at 460 V, and it operates at approximately 2875 rpm (50 Hz) or 3450 rpm (60 Hz). The assembly is identified by Carrier part number 50DK406816 and is commonly listed as an OEM replacement for Carrier systems, often with a 4 MFD capacitor rated 450 V included. Cross‑references align this unit with Fasco models such as JF1H143N (and similar), reflecting its role as the complete inducer motor assembly rather than just a motor component. This part is intended for Carrier furnaces that require the 50DK406816 configuration to drive the draft inducer blower, enabling proper air intake, exhaust venting, and reliable ignition sequence in the heating cycle.
