OEM Carrier Single Run Capacitor Kit 4 MFD + 15 MFD 370V for Model PY3PEA048090NA

This OEM-matched single run capacitor kit contains both factory-specified capacitors for the Carrier PY3PEA048090NA packaged gas/electric unit: the P291-0403 (4 MFD 370V) for the condenser fan motor and the P291-1503 (15 MFD 370V) for the compressor. Each capacitor stores and delivers the precise electrical charge needed to start and sustain its respective motor. When either fails, symptoms include a humming outdoor unit that won't spin up, a compressor that short-cycles, or a tripped high-pressure limit — all leading to a no-cooling condition on a hot day.

  • Specs: P291-0403 — 4 MFD (microfarad) | 370 VAC | Oval case | ±5% factory tolerance. P291-1503 — 15 MFD | 370 VAC | Oval case | ±5% factory tolerance. Both are Totaline/Carrier OEM Polypropylene Film construction, RoHS compliant.
  • OEM vs Generic: Carrier Totaline capacitors are reliability-tested to 60,000 service hours per United Technologies application parameters and subjected to 100% electrical testing at the factory. Generic capacitors often carry ±10% MFD tolerance, accelerating motor wear and shortening compressor life.
  • Install difficulty: 2/5 — Always discharge capacitors fully before handling terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance setting. Photograph all wiring before disconnecting. Replace both capacitors together to eliminate multiple service calls.
  • Warranty: 1-year OEM factory warranty. Orders ship same business day from our warehouse. Compatible successor parts P291-0404 and P291-1504 may ship if OEM stock is fulfilled from updated revision.

Compatibility: This kit is engineered for the Carrier PY3PEA048090NA packaged gas/electric unit. Verify MFD rating and voltage on your unit's data plate before ordering — do not substitute a higher or lower MFD value. Have a question about fitment?

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PEA048090NA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3PEA048090NA. 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 PY3PEA048090NA?
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.
