A direct-replacement exhaust vent blower engineered for specific Intercity furnace models. This Fasco A983 unit restores proper flue draft and combustion venting with OEM-matched speed, voltage, and rotation specs -- so you're not guessing at compatibility. UL and CSA listed for residential and light-commercial installations.
When a furnace flue blower fails, the furnace typically locks out on a pressure-switch fault or simply fails to ignite. This Fasco A983 replacement blower matches the original motor frame, rotation direction, bearing type, and electrical ratings of the Intercity blowers it replaces -- making it a drop-in repair rather than a fabrication project.
The motor uses a C-frame shaded-pole design with ball bearings for long service life. The 1/4" male quick-connect terminals simplify reconnection, and the open air-over construction keeps the motor cool during continuous furnace operation.
CCWSE (counter-clockwise, shaft end) rotation matches original Intercity blower assemblies. Incorrect rotation is a leading cause of pressure-switch lockout after a blower swap.
Ball bearings provide quieter operation and longer service life compared to sleeve-bearing motors, especially in high-cycle furnace duty applications.
Dual safety listing satisfies most jurisdiction requirements for furnace repair work and gives homeowners and technicians peace of mind on the installation.
Rated for ambient temperatures up to 104 deg F (40 deg C). Class B winding insulation handles the heat generated in a typical flue blower application without accelerated degradation.
This blower directly replaces the following Intercity OEM part numbers. Cross-check your existing motor's label before ordering to confirm fitment:
Also catalogued under NBK Parts number 12194 and Fasco model number A983.
The A983 uses a shaded-pole induction motor in an open air-over (OAO) enclosure. Shaded-pole motors are inherently reliable in single-speed blower duty -- there are no brushes, capacitors, or start windings to fail. The open enclosure relies on airflow through the motor for cooling, which is normal and appropriate for a flue blower application where the motor sits in the airstream.
