OEM Payne Dual Run & Start Capacitor Kit for Model PA12NA018000AAAA

This OEM capacitor kit includes both the P291-4053RS Dual Run Capacitor and the P281-8806 Start Capacitor — the factory-specified replacements for the Payne PA12NA018000AAAA single-zone mini-split system. Capacitors store and release the electrical charge required to start and run both the compressor and fan motor. A failing capacitor is one of the most common causes of mini-split failure: symptoms include a loud hum with no motor movement, the system short-cycling within the first few minutes of operation, or the unit refusing to start at all despite the thermostat calling for cooling.

  • OEM Part Numbers: P291-4053RS (Dual Run Capacitor) and P281-8806 (Start Capacitor) — factory-matched tolerances for the Payne PA12NA018000AAAA platform, maintaining ±3% MFD accuracy versus the ±10% common on aftermarket units
  • OEM vs Generic: Factory OEM capacitors are wound to exact voltage and microfarad specifications for this unit. Off-brand substitutes running outside tolerance cause accelerated compressor wear, increased amp draw, and shortened system life — especially critical on inverter-driven mini-split compressors
  • Install Difficulty: 3/5 — Always discharge capacitors before handling any terminals (stored charge can be lethal). Tools needed: insulated screwdrivers, needle-nose pliers, multimeter with capacitance mode, and a discharge resistor or insulated jumper. Photograph all wiring before disconnecting. If unsure, consult a licensed HVAC technician
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse — get your system back up and running fast

Compatibility: This kit is matched to the Payne PA12NA018000AAAA mini-split system. Always verify capacitor MFD and voltage ratings against your unit's data plate before installing. Our fitment team is available to confirm compatibility before you order — don't guess on a safety-critical component.

Frequently Asked Questions

Does this Capacitor fit my Payne PA12NA018000AAAA?
Yes. This is the factory-specified OEM capacitor for the Payne PA12NA018000AAAA. 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 PA12NA018000AAAA?
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.
