OEM Carrier Dual Run Capacitor 45+5 MFD 370V for Model PY2PNB030060NB

This is the factory-specified OEM dual run capacitor for the Carrier PY2PNB030060NB residential split-system air conditioner, supplied under Carrier/Totaline part number P291-4553 (superseded by P291-4554). The dual run capacitor delivers and sustains the electrical charge required to start and run both the compressor and the condenser fan motor simultaneously. A failing capacitor is one of the most common causes of warm air from a working system — symptoms include a loud humming or buzzing with no motor start, a fan that only spins when manually pushed, a compressor that short-cycles within minutes, or a unit that draws high amperage and trips the breaker. Replacing it promptly prevents cascading damage to the compressor and fan motor. This listing also includes the associated single run capacitors P291-0403 and P291-1503 as companion parts for a complete capacitor service on this platform.

  • Specs: 45+5 MFD (microfarad) | 370 VAC rated | Oval case | 50/60 Hz | ±5% factory tolerance | Aluminum construction | UL approved current interrupter | Non-PCB dielectric fluid
  • OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact tolerance specification. Generic aftermarket capacitors frequently run at ±10% MFD deviation, accelerating bearing wear in the fan motor and shortening compressor life — especially during peak summer loads.
  • Install difficulty: 2/5 — Always discharge the capacitor before touching terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Confirm MFD and voltage ratings on the unit data plate before installation.
  • Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse. Includes companion single run capacitors P291-0403 and P291-1503 for complete serviceability.

Compatibility: Engineered for Carrier model PY2PNB030060NB. OEM part numbers covered: P291-4553 (dual run, 45+5 MFD 370V), P291-0403 (single run), P291-1503 (single run). Always verify the MFD, voltage, and physical form factor against your unit's data plate prior to ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY2PNB030060NB?
Yes. This is the factory-specified OEM capacitor for the Carrier PY2PNB030060NB. 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 PY2PNB030060NB?
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.
