OEM Carrier Single Run Capacitor Kit 4 MFD + 15 MFD 370V for Model PY3PEA036090AA

This matched OEM single run capacitor kit contains both factory-specified capacitors for the Carrier PY3PEA036090AA packaged unit — one for the condenser fan motor (P291-0403, 4 MFD) and one for the compressor (P291-1503, 15 MFD). Unlike dual-run systems, this unit uses two discrete oval run capacitors, each tuned to its individual load. When either capacitor degrades, you may notice the system humming without starting, the compressor or fan motor running sluggishly, the unit short-cycling on high-pressure lockout, or tripped breakers from excessive inrush current. Replacing both as a kit at the same time is industry best practice — if one has failed, the other is typically near end-of-life as well.

  • Specs — Fan Motor Capacitor (P291-0403): 4 MFD (µF) | 370V AC | Oval case | ±5% factory tolerance | Replaces OEM P/N P291-0403 / 97F5704
  • Specs — Compressor Capacitor (P291-1503): 15 MFD (µF) | 370V AC | Oval case | ±5% factory tolerance | Replaces OEM P/N P291-1503 / 97F9004
  • OEM vs Generic: These are genuine Carrier/Totaline-spec capacitors manufactured to exact factory tolerances. Generic aftermarket capacitors often run ±10% MFD drift, which accelerates motor winding wear, reduces compressor life, and can void equipment warranties. Always match MFD rating exactly — voltage may be equal or higher.
  • Install difficulty: 2/5 — Disconnect power at the disconnect box and verify zero voltage with a multimeter before touching any terminals. Discharge capacitors using an insulated resistor or discharge tool. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing old capacitors. Note wire colors and terminal labels (HERM, FAN, C/COM).
  • Warranty: 1-year OEM factory warranty on both capacitors. Orders placed before 3 PM ship same business day from our warehouse.

Compatibility: This kit is engineered specifically for the Carrier PY3PEA036090AA 3-ton packaged unit. Verify MFD ratings and voltage on your unit's data plate before ordering — do not substitute a dual-run capacitor for these individual single-run units without verifying wiring compatibility. Have questions about fitment? Our HVAC parts specialists confirm compatibility before you order — no guesswork.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor Kit 4+15 MFD 370V — PY3PEA036090AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor Kit 4+15 MFD 370V — PY3PEA036090AA. 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 OEM Carrier Single Run Capacitor Kit 4+15 MFD 370V — PY3PEA036090AA?
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?
