OEM Payne Dual Run Capacitor & Start Capacitor for Model PA10JA042000ACAA

This OEM-matched capacitor set — dual run capacitor P291-4054RS and start capacitor P281-8806 — is the factory-specified replacement for the Payne PA10JA042000ACAA split-system air conditioner. The dual run capacitor continuously supports both the compressor and condenser fan motor during operation, while the start capacitor delivers the extra electrical torque needed to kick the compressor into motion under load. When either component fails, symptoms typically include a persistent hum with no motor movement, the system tripping its thermal overload, compressor hard-starting, or the unit shutting down within the first few minutes of operation.

  • Specs: Dual Run Capacitor P291-4054RS — 40+5 MFD | 370V/440V dual-rated | Round case | ±5% factory tolerance. Start Capacitor P281-8806 — High-capacitance boost rating | Compatible with standard start-assist kits | Matched to Payne PA10JA042000ACAA compressor specifications.
  • OEM vs Generic: OEM capacitors are manufactured to exact Payne/Carrier factory tolerances. Aftermarket substitutes frequently drift ±10% MFD from their rated value, placing additional thermal and electrical stress on the compressor and fan motor — leading to premature failures and voided equipment warranties.
  • Install Difficulty: 2/5 — Capacitors store lethal voltage even after power is cut. Always disconnect power at the breaker and discharge the capacitor across its terminals using an insulated resistor or discharge tool before touching any leads. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance mode. Photograph all wiring connections before removal.
  • Warranty: 1-year OEM factory warranty on both components. Orders placed before cut-off ship same business day from our climate-controlled warehouse.

Compatibility: Engineered for the Payne PA10JA042000ACAA 3.5-ton split-system air conditioner. Always verify MFD, voltage rating, and terminal configuration against your unit's data plate and existing capacitor markings before installation. Our fitment team is available to confirm compatibility before you order — same-day shipping means your system is back online fast.

Frequently Asked Questions

Does this Capacitor fit my Payne PA10JA042000ACAA?
Yes. This is the factory-specified OEM capacitor for the Payne PA10JA042000ACAA. 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 PA10JA042000ACAA?
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.
