OEM Carrier Single Run Capacitor HC91PD001 for Model PG9MAA060120ACKA

This is the factory-specified OEM single run capacitor for the Carrier PG9MAA060120ACKA gas furnace. The run capacitor provides the continuous phase-shifted electrical current that keeps the blower motor running at rated speed and efficiency. When this capacitor weakens or fails, symptoms include a humming blower motor that won't spin up, intermittent airflow, overheating due to reduced motor RPM, or a complete blower no-start condition — all of which can trigger a system lockout or fault code on your control board.

• OEM Part Numbers: HC91PD001 (primary) | P291-1003 (cross-reference) — both are factory-authorized designations for this single run capacitor. Verify the MFD rating and voltage on your unit's data plate or existing capacitor before ordering.
• OEM vs Generic: This is a genuine Carrier OEM capacitor manufactured to exact factory tolerances (typically ±3% MFD). Generic aftermarket capacitors often carry a ±10% tolerance, which accelerates blower motor winding stress and shortens operational life — especially problematic on ECM-adjacent applications.
• Install Difficulty: 2/5 — A straightforward single-component swap accessible through the blower compartment. Required tools: 1/4" nut driver, needle-nose pliers, and a multimeter. Critical safety step: Always discharge the capacitor across its terminals with an insulated resistor before handling. Photograph all wiring connections before disconnecting.
• Warranty & Shipping: Backed by a 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed and factory-matched for the Carrier PG9MAA060120ACKA gas furnace. This unit is a 5-ton, 120,000 BTU/hr, 80% AFUE upflow/horizontal gas furnace. Confirm the MFD and voltage rating on your existing capacitor or equipment data plate prior to ordering to ensure a perfect fit. Have questions about fitment?
