OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA024040ADKA

This is the factory-specified OEM single run capacitor for the Carrier PG9MAA024040ADKA two-stage 96% AFUE gas furnace. Carrying OEM part numbers HC91PD001 and P291-0753, this rectangular 3 MFD 250V capacitor is mounted in the furnace's blower section and provides the sustained electrical charge that keeps the indoor blower motor running at proper speed. When this capacitor weakens or fails, you'll typically notice a humming blower motor that won't spin up, intermittent blower operation, motor overheating, or a blower that runs sluggishly — all symptoms that can trigger nuisance lockouts and reduced heating efficiency in your two-stage system.

• Specs: 3 MFD (microfarad) | 250V rated | Rectangular case | ±5% tolerance | 50/60 Hz | CSA listed — exact factory replacement dimensions: 1.10" H × 0.87" L × 0.94" W
• OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact factory tolerance of ±5% MFD. Off-brand generic capacitors frequently run ±10% or wider, placing added stress on blower motor windings and shortening motor life — a costly consequence on a high-efficiency two-stage furnace.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Discharge the capacitor terminals using an insulated resistor before touching any leads. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph or label wire positions before removing the old capacitor.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse when ordered by 3 PM local time.

Compatibility: Engineered for the Carrier PG9MAA024040ADKA two-stage 96% AFUE gas furnace. Cross-references include OEM part numbers HC91PD001 and P291-0753. Always verify the MFD rating and voltage on your existing capacitor's label or unit data plate before ordering to ensure a correct match.
