OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA048100AEKA (HC91PD001)

This is the genuine OEM Carrier replacement single run capacitor (part number HC91PD001) factory-specified for the Carrier PG9MAA048100AEKA gas furnace. The run capacitor provides a sustained electrical charge to keep the draft inducer blower motor operating at peak efficiency throughout each heating cycle. When this capacitor begins to fail, you may notice the inducer motor becoming excessively noisy, running hot to the touch, slowing down under load, or failing to start altogether — any of which can trigger a pressure switch lockout and leave you without heat.

• Specs: 3 MFD (microfarad) | 250V AC rated | Rectangular case (square body) | ±5% tolerance | 50/60 Hz | Manufactured by ASC Capacitors (ShiZuki model CMKS-X345) | Country of Origin: Japan
• OEM vs Generic: This is a genuine Carrier OEM part, matched to the exact factory tolerance of ±5%. Generic aftermarket capacitors frequently exceed ±10% variance, which places increased electrical stress on the inducer motor windings and shortens motor life significantly.
• Install difficulty: 2/5 — A straightforward single-capacitor swap. Discharge the capacitor before handling any terminals. Recommended tools: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring orientation before disconnecting the old capacitor.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG9MAA048100AEKA gas furnace. This part also fits a wide range of Carrier, Bryant, and Payne gas furnace models that use the same draft inducer assembly. Always verify the MFD rating and voltage on your existing capacitor's label or your unit's wiring diagram before ordering. Our team is available to confirm fitment — just reach out before you buy.
