OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA048080ACKA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG9MAA048080ACKA gas furnace. Rated at 3 MFD at 250V, this compact rectangular capacitor is dedicated to sustaining the draft inducer motor's run cycle. When this capacitor degrades or fails, the inducer motor struggles to reach operating speed or stalls entirely — resulting in a pressure switch fault, ignition lockout, or a no-heat condition. If your furnace is starting then shutting down, flashing an inducer fault code, or failing to light altogether, this is a critical first part to test and replace.

• Specs: 3 MFD (microfarad) | 250V rated | Rectangle case | 50/60 Hz | ±5% tolerance | CSA listed | Dimensions: 1.10" H × 0.87" L × 0.94" W
• OEM vs Generic: This is a genuine OEM Carrier part (HC91PD001 / P291-1003) manufactured to factory-exact ±5% MFD tolerance. Generic alternatives often drift beyond ±10%, causing premature inducer motor wear and nuisance faults.
• Install difficulty: 2/5 — Always discharge the capacitor fully before removing terminals. Tools needed: Phillips screwdriver, needle-nose pliers, multimeter with capacitance setting. Photograph existing wiring before disconnecting. The inducer motor is typically accessible after removing the furnace access panel.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our stocked warehouse.
