OEM Carrier Single Run Capacitor P291-1503 for Model PG8HAA048075AAJA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PG8HAA048075AAJA gas furnace. The run capacitor maintains a continuous phase-shifted current to keep the blower (indoor air handler) motor spinning at full efficiency throughout each heating cycle. When this capacitor begins to fail, you'll notice symptoms such as a blower motor that hums but won't spin, sluggish startup, the unit short-cycling, or a furnace that locks out on a high-limit fault because airflow is insufficient. Replacing it promptly protects the blower motor from overheating and premature burnout — a repair that costs significantly more.

• Specs: Single run capacitor | Factory-matched MFD rating and voltage | Round or oval case per OEM spec | Tight ±5% tolerance for reliable motor performance
• OEM vs Generic: This is a genuine Carrier OEM part. Generic capacitors frequently ship with ±10–15% MFD tolerance, causing motor strain, reduced efficiency, and shortened component life. OEM ensures an exact factory match every time.
• Install Difficulty: 2/5 — A straightforward swap for any experienced DIYer or HVAC technician. Always disconnect power at the breaker and discharge the capacitor before touching terminals. Tools needed: flathead and Phillips screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter. Photograph all wiring connections before removal.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PG8HAA048075AAJA packaged gas furnace.
