OEM Payne Run Capacitor (P291-4054RS / P291-1503) for Model PA1ZNA042000ABAA

This is the factory-specified OEM replacement run capacitor for the Payne PA1ZNA042000ABAA split-system air conditioner. Available in two configurations — the P291-4054RS dual run capacitor (powers both compressor and condenser fan motor) and the P291-1503 single run capacitor (dedicated single-load application). The capacitor stores and releases the electrical charge necessary to start and sustain motor operation. Common failure symptoms include a loud humming with no motor start, the condenser fan spinning slowly or not at all, compressor short-cycling, or the system tripping the breaker repeatedly.

  • OEM Part Numbers: P291-4054RS (Dual Run Capacitor) | P291-1503 (Single Run Capacitor) | 370V/440V rated | Round case | Factory-matched ±3% MFD tolerance for precise motor protection
  • OEM vs Generic: OEM Payne capacitors are manufactured to exact ICP/Carrier factory tolerances. Aftermarket capacitors frequently deviate ±10% MFD, which accelerates compressor wear, shortens motor life, and can void equipment warranties.
  • Install difficulty: 2/5 — Always discharge the capacitor before handling terminals — stored charge can cause serious injury. Tools needed: 1/4" nut driver, needle-nose pliers, insulated screwdriver, and a multimeter for post-install verification. Photograph all wiring connections before disconnecting the old capacitor.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. Orders placed before our same-day cutoff ship from our warehouse the same business day — no waiting on backorders.

Compatibility & Ordering: Designed specifically for the Payne PA1ZNA042000ABAA 3.5-ton split-system air conditioner. Before ordering, confirm the MFD rating and voltage printed on your existing capacitor's label or the unit's data plate to ensure you select the correct configuration — dual run (P291-4054RS) or single run (P291-1503). Not sure which one you need? Our HVAC parts specialists verify fitment before every order — contact us and we'll confirm the right part for your unit. In-stock and ready to ship today.

Frequently Asked Questions

Does this Capacitor fit my Payne PA1ZNA042000ABAA?
Yes. This is the factory-specified OEM capacitor for the Payne PA1ZNA042000ABAA. 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 capacitor on my Payne PA1ZNA042000ABAA?
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 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 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?
