The Packard 66755 is a direct-replacement draft inducer blower motor engineered to restore proper combustion airflow in Carrier furnaces that use OEM part number 309868755. This kit ships complete with the motor, blower wheel, capacitor, mounting bracket, and lead adapters -- everything needed to complete the swap without hunting for separate components.
Draft inducer motors are safety-critical components. They evacuate combustion gases before ignition and maintain proper venting throughout the heat cycle. When the original Carrier 309868755 motor fails -- often indicated by a pressure switch fault code or visible shaft wobble -- the Packard 66755 provides a confirmed drop-in fit with matched electrical and mechanical specs.
Unlike bare-motor replacements that leave you scrambling for a matching blower wheel or capacitor, the 66755 kit includes every major installation component. The PSC (Permanent Split Capacitor) motor design delivers quiet, efficient single-speed operation with automatic overload protection built in.
Motor, blower wheel, capacitor, mounting bracket, and lead adapters are all included -- ready to install without additional parts.
Permanent Split Capacitor type for reliable single-speed operation, lower noise, and efficient current draw at 0.86 amps.
Ball bearings provide longer service life and smoother operation compared to sleeve-bearing alternatives in high-cycle furnace applications.
Built-in thermal overload protection shuts the motor down if it overheats, protecting both the motor and the furnace control board.
A draft inducer (also called a combustion inducer or induced draft blower) is a small, high-speed motor-and-wheel assembly mounted at the heat exchanger outlet. It creates a negative pressure that pulls combustion air through the burners and pushes flue gases out the vent pipe before and during the heat cycle. The furnace's pressure switch verifies that the inducer is running before allowing ignition -- so a failed inducer motor means a furnace that locks out on a fault code and will not heat.
The Packard 66755 is specifically validated to replace Carrier OEM part number 309868755. It is also cataloged under NBK Parts number 20292. If your existing inducer assembly carries that Carrier part number on its label, the 66755 is the correct replacement.
The included mounting bracket and lead adapters are designed to align with the existing Carrier furnace mounting holes and wiring harness, minimizing modification. Confirm the OEM part number on your existing inducer assembly before ordering. Disconnect power and allow the heat exchanger to cool before beginning any inducer motor replacement.
