OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PY1PJB048130NBAA

This is the factory-specified OEM dual run capacitor for the Carrier PY1PJB048130NBAA packaged unit. The dual run capacitor stores and delivers the electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. When it degrades or fails, you'll notice symptoms such as a loud hum with no motor movement, the system blowing warm air, short-cycling within minutes of startup, or a complete no-start condition. Replacing it with the correct OEM part restores factory-spec performance and protects downstream components like the compressor from damaging low-voltage starts.

  • Specs — Primary (P291-4054): 40+5 MFD (microfarad) | 370–440V rated | Round case | Dual run (compressor + fan) | ±5% factory tolerance | Also cross-references OEM single run capacitors P291-0403 (4 MFD 370V) and P291-1503
  • OEM vs. Generic: OEM Carrier capacitors are manufactured to exact factory tolerance and undergo 100% electrical testing. Generic aftermarket units frequently run at ±10% MFD variance, which accelerates motor winding fatigue and can shorten compressor life by months.
  • Install Difficulty: 2/5 — Discharge the capacitor fully before touching any terminals — stored charge can cause serious injury. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Always photograph the existing wiring before disconnecting terminals (HERM, FAN, C).
  • Warranty & Shipping: Backed by a 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered by cutoff.

Compatibility: Engineered as the direct OEM replacement for Carrier model PY1PJB048130NBAA. Includes dual run capacitor P291-4054 (40+5 MFD 440V round) and cross-references single run capacitors P291-0403 and P291-1503. Always verify MFD rating, voltage, and terminal configuration against your unit's data plate before ordering. Need help confirming fitment?

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1PJB048130NBAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY1PJB048130NBAA. 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 PY1PJB048130NBAA?
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.
