OEM Carrier Single Run Capacitor 15 MFD 370V for Model PY3PNA048090AA

This OEM Carrier single run capacitor is the factory-specified replacement for the Carrier PY3PNA048090AA packaged unit. Single run capacitors store and release the precise electrical charge required to start and sustain the compressor or condenser fan motor during each operating cycle. When a run capacitor fails, you'll typically notice a loud hum with no motor start, intermittent short-cycling, a tripped breaker, or the system shutting down within seconds of startup — all classic signs of capacitor degradation.

  • Specs: 15 MFD (microfarad) | 370V rated | Oval case | Factory-matched ±5% tolerance | Replaces OEM part numbers P291-1503 and P291-0403 (successor parts P291-1504 / P291-0404)
  • OEM vs Generic: OEM Carrier/Totaline capacitors are reliability-tested to 60,000 service hours and use high-grade metallized polypropylene film (5–12 microns thick). Generic capacitors often carry wider tolerance ranges that accelerate motor wear and reduce compressor lifespan.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old capacitor. Note: Carrier sources its capacitors from OEM manufacturers — the label on the capacitor body will reflect the original manufacturer's name, not Carrier.
  • Warranty: 1-year OEM factory warranty. Orders placed before 3 PM ship same business day from our warehouse.

Compatibility: Designed for use in Carrier model PY3PNA048090AA packaged units. Always verify the MFD and voltage rating on your unit's data plate before ordering. Both P291-0403 (4 MFD 370V) and P291-1503 (15 MFD 370V) are OEM single run capacitors used in this platform — confirm which capacitor your unit requires before purchasing. Questions about fitment? Our HVAC parts team verifies compatibility before every order ships.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PNA048090AA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3PNA048090AA. 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 PY3PNA048090AA?
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.
