OEM Carrier Dual Run Capacitor (P291-4573RS) & Start Capacitor (P281-8806) for Model PH13NR030000AFAA

This factory-matched capacitor kit includes both the dual run capacitor (P291-4573RS) and the start capacitor (P281-8806) specified for the Carrier PH13NR030000AFAA heat pump condenser. The dual run capacitor continuously supplies the phase-shifted current required to keep the compressor and condenser fan motor running. The start capacitor delivers a high-torque boost at startup to get the compressor spinning under load. When either capacitor degrades, you'll experience symptoms ranging from a humming compressor that won't start, frequent short-cycling, tripped breakers, or a complete no-cooling condition — often on the hottest day of the year.

  • Dual Run Capacitor Specs (P291-4573RS): 45 + 7.5 MFD (microfarad) | 370 VAC | Round case | Factory ±3% tolerance | Replaces HC98JA047, GE 97F9969
  • Start Capacitor Specs (P281-8806): 88–108 MFD | 330 VAC | Round case with bleed resistor | Genuine Carrier Totaline OEM
  • OEM vs Generic: OEM capacitors are reliability-tested to 60,000 service hours per Carrier application parameters and use high-grade metallized polypropylene film. Generic units often ship with ±10% MFD tolerance, accelerating compressor wear and voiding equipment warranties.
  • Install Difficulty: 2/5 — Always discharge capacitors before touching terminals (stored charge can exceed 370V). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wiring before disconnecting. Verify MFD and voltage ratings on your unit's data plate before installation.
  • Warranty: 1-year OEM factory warranty on both capacitors. Orders ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PH13NR030000AFAA heat pump condenser. Note: P291-4573RS has been superseded by P291-4574RS (440V upgrade) — both are fully compatible. Verify MFD ratings on your existing capacitors before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH13NR030000AFAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH13NR030000AFAA. 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 Carrier PH13NR030000AFAA?
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 Carrier 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 Carrier 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.
