OEM Carrier Dual Run Capacitor 45+5 MFD 440V for Model PY4GNAB42060NA

This is the factory-specified OEM dual run capacitor (part number P291-4554RS) for the Carrier PY4GNAB42060NA packaged unit. The dual run capacitor stores and releases the precise electrical charge needed to start and continuously run both the compressor and condenser fan motor. A failing capacitor is one of the most common causes of HVAC failure in the summer — symptoms include a humming unit that won't start, a compressor that short-cycles within minutes of starting, or a condenser fan that spins slowly or not at all. Replacing this part promptly prevents compressor burnout, which is a far more costly repair.

  • Specs: 45+5 MFD (microfarad) | 370/440V dual-rated | Round case | 50/60 Hz | Factory-matched ±5% tolerance per IEC standards
  • OEM vs Generic: This is a genuine Carrier OEM part (P291-4554RS). OEM capacitors are built to exact factory MFD tolerances, protecting your compressor and fan motor from accelerated wear. Generic units often deviate ±10% MFD, shortening component life and potentially voiding equipment warranties. Note: Carrier sources capacitors from approved third-party manufacturers — the label may reflect the capacitor manufacturer's name, not Carrier's.
  • Install Difficulty: 2/5 — Capacitors store a lethal charge even when power is off. Always discharge the capacitor using an insulated resistor or discharge tool before touching terminals. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify full discharge. Photograph all wiring connections before disconnecting the old unit.
  • Warranty & Shipping: Backed by a 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered before the cutoff.

Compatibility: Designed as the direct OEM replacement for the Carrier PY4GNAB42060NA packaged unit. Always verify the MFD rating and voltage printed on your existing capacitor's data label before ordering — mismatched MFD values can damage motors. Also a direct replacement for Carrier part HC98KA046. Have a fitment question? Our HVAC parts specialists verify compatibility before you buy — contact us before placing your order.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY4GNAB42060NA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY4GNAB42060NA. 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 PY4GNAB42060NA?
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.
