OEM Payne Run Capacitor P291-4554 for Model PA12NA048000AAAA

This OEM Payne dual run capacitor (P291-4554, 45/5 MFD, 440V) keeps your air conditioner's compressor and condenser fan motor running at peak efficiency. Engineered as a direct factory replacement for the Payne PA12NA048000AAAA 4-ton condensing unit, it delivers the precise microfarad rating your system was designed for, preventing hard starts, motor overheating, and short cycling. A failing run capacitor is one of the most common causes of an AC unit that hums but won't start. Installation is straightforward for most homeowners with basic tools—discharge the old capacitor, note the terminal markings (HERM, FAN, C), and swap in the replacement in about 15 minutes. Always shut off power at the disconnect first. Using a genuine OEM-spec capacitor ensures correct tolerance and UL-listed safety, unlike generic substitutes. In stock and ready to ship. Orders placed before 3PM CST ship the same business day, so you can get your cooling back fast. Backed by our HVAC parts expertise and fast nationwide delivery.

Frequently Asked Questions

Does this Run Capacitor fit my Payne Model PA12NA048000AAAA?
Yes. This is the factory-specified OEM run capacitor for the Payne Model PA12NA048000AAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the run capacitor on my Payne Model PA12NA048000AAAA?
Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.
My AC hums but won’t start. What part do I need?
An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).
Is this run capacitor compatible with Bryant or Payne too?
Many Payne parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Payne run capacitor?
OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.
How fast does National HVAC Parts ship?
