OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA048100AFKA (HC91PD001)

This is the genuine OEM Carrier single run capacitor (part number HC91PD001), factory-specified for the Carrier PG9MAA048100AFKA gas furnace. The run capacitor stores and releases the electrical charge needed to start and sustain the draft inducer blower motor. When this capacitor degrades or fails, you may notice the inducer motor humming without spinning, running noisily, overheating and tripping the thermal cutout, or failing to start entirely — all of which can prevent the furnace from completing its ignition sequence.

• Specs: 3 MFD (microfarad) | 250V AC rated | Rectangular/square case | ±5% tolerance | 50/60 Hz | Manufactured by ASC Capacitors (CMKS-X345)
• OEM vs Generic: This is a genuine Carrier OEM part, built to exact factory tolerances. Aftermarket capacitors frequently drift outside ±10% MFD tolerance, causing premature inducer motor wear and repeated failures — especially in high-cycle furnace applications.
• Install difficulty: 2/5 — Discharge the capacitor fully before touching terminals. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter (capacitance setting). Always photograph existing wiring before disconnecting. The rectangular form factor requires matching the correct terminal orientation on reinstall.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders ship same business day from our stocked warehouse.

Compatibility: Designed for the Carrier PG9MAA048100AFKA gas furnace and compatible Carrier, Bryant, and Payne models using the HC91PD001 inducer motor run capacitor. Always verify the MFD rating, voltage, and capacitor shape on your unit's data plate or existing capacitor before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
