OEM Carrier Single Run Capacitor Kit 4 MFD & 15 MFD 370V for Model PY3PEA036090NA

This OEM-matched single run capacitor kit contains both factory-specified capacitors for the Carrier PY3PEA036090NA packaged unit: the P291-0403 (4 MFD 370V oval) for the condenser fan motor and the P291-1503 (15 MFD 370V oval) for the compressor circuit. Run capacitors provide the continuous phase-shifted current that keeps motors running efficiently after startup. When either capacitor weakens or fails, you may notice the compressor or fan motor humming but not spinning, the unit short-cycling within minutes of startup, higher-than-normal energy consumption, or complete failure to cool. Replacing both at the same service call is best practice — a weakened companion capacitor dramatically shortens the life of a new one.

  • Specs — P291-0403: 4 MFD (microfarad) | 370V | Oval case | Carrier Totaline factory part | ±5% capacitance tolerance | RoHS compliant
  • Specs — P291-1503: 15 MFD (microfarad) | 370V | Oval case | Carrier Totaline factory part | UL approved with patented pressure-sensitive interrupter | Proven to 60,000 service hours
  • OEM vs Generic: Carrier Totaline OEM capacitors are 100% electrically tested at the factory and built to United Technologies reliability standards. Generic capacitors often carry ±10% MFD tolerances, increasing motor stress and accelerating wear on compressor windings and fan bearings.
  • Install difficulty: 2/5 — Discharge both capacitors fully before handling (use a 20kΩ resistor or insulated screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring before disconnecting. Match the MFD and voltage on your unit's data plate before installation.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PY3PEA036090NA packaged gas/electric unit. Verify both MFD ratings and voltage on the unit's data plate before ordering. Note: P291-1503 has been superseded by P291-1504 (440V upgrade) — both are compatible. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — reach out before checkout.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PEA036090NA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3PEA036090NA. 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 PY3PEA036090NA?
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.
