OEM Carrier Single Run Capacitor 10 MFD 440V for Model PG8UAA048111ADJA

This OEM single run capacitor is the factory-authorized replacement for the Carrier PG8UAA048111ADJA gas furnace. Originally supplied as part number P291-1003 and now updated to its direct successor P291-1004, this capacitor provides the continuous electrical charge required to keep the blower motor running efficiently throughout every heating and cooling cycle. When this capacitor weakens or fails, you'll typically notice the blower motor humming but failing to start, sluggish airflow, or the furnace shutting down mid-cycle due to motor overload — all classic signs of capacitor degradation.

• Specs: 10 MFD (microfarad) | 370/440V rated | Oval case | Factory-matched ±5% tolerance | 50/60 Hz | RoHS compliant
• OEM vs Generic: This OEM Carrier/Totaline capacitor is reliability-tested to 60,000 service hours per United Technologies specifications and uses high-grade metallized polypropylene film. Generic alternatives often carry wider MFD tolerances, accelerating motor wear over time.
• Install difficulty: 2/5 — Always discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. This is a straightforward swap accessible in the blower compartment.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
