Carrier HC21ZS122 Inducer Motor

The Carrier HC21ZS122 Inducer Motor is the direct engineering successor to the HC21ZE122A, designed to maintain critical negative pressure within the furnace’s heat exchanger. This OEM draft inducer motor operates at 115V and 3000 RPM, ensuring atmospheric contaminants and combustion byproducts are safely exhausted through the flue. As a veteran-grade furnace replacement motor, it features high-durability ball bearings and a 1.05 FLA rating, providing the precise torque needed to close the furnace pressure switch and initiate the ignition sequence without intermittent "Failed to Ignite" codes. Specifically calibrated for Carrier, Bryant, and Payne furnaces, this single-phase, CCW-rotation unit eliminates the need for field modifications or bracket adjustments. When diagnosing a noisy inducer motor or a seized shaft, swapping in this genuine Carrier part restores factory-spec airflow and efficiency, preventing the common roll-out trips associated with aging or aftermarket assemblies.

• Exact Drop-In Replacement: Specifically engineered to replace HC21ZE122A and HC21ZE122, ensuring a perfect OEM inducer motor fit without housing modifications.
• High-Velocity Performance: The 3000 RPM output is calibrated to meet strict static pressure requirements for consistent furnace ignition.
• Robust Build Quality: Features internal ball bearings and Class B insulation to withstand high-heat exhaust environments.
• Simplified Wiring: Designed for standard 115V/60Hz single-phase systems, facilitating rapid field installation.

What are the signs that a Carrier HC21ZS122 motor needs replacement?
Common indicators include a loud grinding or rattling noise during the pre-purge cycle, a failure of the pressure switch to close, or the motor failing to spin despite receiving 115V from the control board.

Does this motor require a separate run capacitor?
No, the HC21ZS122 is a shaded-pole or permanent split capacitor design (depending on the specific production run) that typically does not require an external capacitor, making it a streamlined furnace repair part.

Is this unit compatible with Bryant and Payne models?
Yes, as a Factory Authorized Part, it is the standard induced draft motor for several 58STA, 58STX, and 310AAV series units across the Carrier family of brands.
