OEM Carrier Single Run Capacitor HC91PD001 for Model PG9MAA060140ADKA

This OEM single run capacitor (part numbers HC91PD001 and P291-1003) is the factory-specified replacement for the Carrier PG9MAA060140ADKA gas furnace. The run capacitor maintains the correct phase shift needed to keep the blower motor spinning efficiently at rated torque. When it degrades or fails, you'll typically notice the blower motor humming without turning, starting slowly and then shutting off, or causing the furnace to lock out on a high-limit fault due to insufficient airflow across the heat exchanger.

• Specs: Single run capacitor | Factory-matched MFD rating | 370V or 440V rated (verify on unit data plate) | Round or oval case per OEM specification | ±5% tolerance factory standard
• OEM vs Generic: This is a genuine Carrier OEM part carrying the exact capacitance and voltage rating specified at the factory. Generic alternatives often carry a wider ±10% MFD tolerance, which can accelerate motor winding wear and shorten blower motor life — especially in high-run-time heating applications.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before disconnecting terminals (use a 20kΩ resistor or dedicated discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance setting. Photograph all wiring connections before removal.
• Warranty: 1-year OEM manufacturer warranty. Orders placed before cut-off ship same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PG9MAA060140ADKA gas furnace. Always confirm the MFD rating and voltage stamped on your existing capacitor or on the unit's data plate before ordering. Cross-reference part numbers HC91PD001 and P291-1003 — both are the same component under different catalog references. Have a question about fitment?
