OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA048080AAKA

This factory-authorized single run capacitor (part numbers HC91PD001 and P291-1003) is the OEM-specified replacement for the Carrier PG9MAA048080AAKA Performance 80% gas furnace. This compact rectangular capacitor serves the draft inducer motor, storing and releasing the electrical charge needed to start and sustain inducer motor operation on every heating cycle. When this capacitor weakens or fails, you'll typically notice the inducer motor humming but failing to spin, a pressure switch lockout fault code, or a furnace that attempts ignition but shuts down before the burners light — leaving your home without heat.

• Specs: 3 MFD (microfarad) | 250V rated | Rectangle/square case | ±5% tolerance | 50/60 Hz | 10,000 AFC | CSA listed | Manufacturer: ASC Capacitors (ShiZuki CMKS-X345)
• OEM vs Generic: This is a genuine Factory Authorized Part engineered to Carrier's exact ±5% MFD tolerance. Generic capacitors commonly run ±10–20%, causing the inducer motor to run hotter, shortening its service life and risking repeat failures within a single season.
• Install difficulty: 2/5 — A straightforward capacitor swap on the inducer motor. Tools needed: 1/4" nut driver or screwdriver, needle-nose pliers, multimeter (to verify discharge). Always discharge the capacitor across its terminals before handling. Photograph existing wiring connections before removal.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.
