A direct-replacement draft inducer blower motor built to match the original Fasco A150 specification. Designed for residential and light-commercial furnaces from Fasco and Trane, this shaded-pole motor delivers reliable combustion airflow with ball-bearing construction and built-in thermal overload protection. Also cataloged as NBK Parts 12178 and Packard 82253.
The draft inducer motor is one of the most cycle-intensive components in a forced-air furnace. It must spin up reliably on every call for heat, maintain consistent airflow through the heat exchanger, and survive thousands of on/off cycles over its service life. When the original Fasco or Trane inducer motor fails -- shown by a humming but non-spinning wheel, a furnace that locks out on pressure-switch fault, or an audibly grinding bearing -- this A150 motor restores full function without modification.
This motor ships with 24-inch stripped leads ready for direct connection to the OEM wire harness. No adapter harness or bracket fabrication is required for the compatible models listed below.
Ball bearings -- not sleeve bearings -- handle the heat and vertical shaft loads common in inducer applications, providing longer service life in high-cycle furnace environments.
Integrated thermal overload protector shuts the motor down before winding damage occurs if airflow is restricted or ambient temps exceed the rated 104 deg F / 40 deg C limit.
Meets UL and CSA safety standards required for furnace blower motor replacements in the US and Canada. Suitable for permitted HVAC service work.
Class B winding insulation is rated to 266 deg F (130 deg C), providing a meaningful thermal margin above the motor's operating range in typical furnace applications.
This motor is a verified replacement for the following OEM and aftermarket part numbers. If your existing motor carries any of these numbers on its label, the Fasco A150 / NBK 12178 is the correct replacement.
If your furnace exhibits any of the following, the draft inducer motor is a common cause:
