OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA048100AAKA

This is the factory-specified OEM single run capacitor for the Carrier PG9MAA048100AAKA gas furnace. The run capacitor maintains a continuous phase-shift voltage to keep the blower or draft inducer motor spinning at proper speed and efficiency. When this capacitor weakens or fails, you'll notice symptoms such as slow motor start-up, reduced airflow, motor humming without full rotation, overheating, or a complete motor failure — leaving your furnace unable to complete a heating cycle.

• Specs: 3 MFD (microfarad) | 250V rated | Rectangular case | ±5% tolerance | 50/60 Hz | CSA listed | Factory Authorized Part
• OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact factory tolerance of ±5% MFD, ensuring proper motor performance and longevity. Generic alternatives often carry ±10% or wider tolerances, which can cause premature motor wear or shortened capacitor life in continuous-duty furnace applications.
• Install difficulty: 2/5 — Discharge the capacitor before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (capacitance setting). Always photograph existing wiring before disconnecting terminals. Power down and lock out the furnace at the breaker before beginning work.
• Warranty & Shipping: 1-year OEM factory warranty against manufacturing defects. In stock — ships same business day from our warehouse when ordered by cutoff time.
