OEM Payne Dual Run & Start Capacitor for Model PA12NA042000ACAA

These factory-specified OEM replacement capacitors — dual run capacitor P291-5573RS and start capacitor P281-8806 — are engineered for the Payne PA12NA042000ACAA single-stage split-system air conditioner. The dual run capacitor stores and delivers the electrical charge needed to start and sustain both the compressor and condenser fan motor during every cooling cycle. The start capacitor provides an additional boost of starting torque to get the compressor spinning under load. When either fails, you'll notice symptoms such as a constant hum with no motor movement, repeated short-cycling, a condenser fan that won't spin, or a compressor that trips the breaker shortly after startup — all classic signs of capacitor failure on the PA12NA042000ACAA.

  • Specs: Dual Run Capacitor P291-5573RS — round case, 440V rated, factory-matched ±5% MFD tolerance | Start Capacitor P281-8806 — high-torque start boost, matched to PA12NA042000ACAA compressor specifications | Both rated for R-410A refrigerant system electrical loads
  • OEM vs Generic: These OEM capacitors meet Payne's exact factory tolerances, ensuring proper compressor start torque and sustained run performance. Generic alternatives frequently drift ±10% MFD from rated value, accelerating compressor and motor wear and shortening overall system lifespan.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals — stored voltage can cause serious injury. Tools needed: 1/4" nut driver, needle-nose pliers, insulated screwdriver, and a multimeter to verify capacitance. Photograph all wiring connections before disconnecting. A qualified HVAC technician is recommended if you are unfamiliar with high-voltage components.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse to get your Payne system cooling again fast.

Compatibility: Designed specifically for the Payne PA12NA042000ACAA 3.5-ton split-system air conditioner. Always verify MFD and voltage ratings against your unit's data plate before installation. Our fitment team is available to confirm compatibility before you order — don't let a failed capacitor keep you in the heat any longer than necessary.

Frequently Asked Questions

Does this Capacitor fit my Payne PA12NA042000ACAA?
Yes. This is the factory-specified OEM capacitor for the Payne PA12NA042000ACAA. 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 PA12NA042000ACAA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
