OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA048100ACKA

This is the factory-specified OEM single run capacitor for the Carrier PG9MAA048100ACKA gas furnace. The run capacitor delivers and sustains the electrical charge required to keep the draft inducer blower motor running through each heating cycle. When this capacitor fails, the inducer motor may hum without spinning, run noisily, overheat and trip its thermal cutout, or fail to start entirely — triggering a pressure switch lockout and a no-heat condition. OEM part numbers HC91PD001 and P291-1003 are both factory-authorized references for this component.

• Specs: 3 MFD (microfarad) | 250V AC rated | Rectangular/square case | ±5% tolerance | 50/60 Hz | Manufacturer: ASC Capacitors (CMKS-X345)
• OEM vs Generic: This OEM capacitor is built to exact Carrier factory specifications with tight ±5% MFD tolerance. Generic alternatives commonly run ±10% or wider, increasing motor stress and shortening inducer motor service life.
• Install difficulty: 2/5 — Discharge the capacitor before handling any terminals. Tools needed: flat-blade and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph existing wiring before disconnecting terminals.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our stocked warehouse.
