OEM Carrier Dual Run Capacitor 50+5 MFD 370V for Model PY3PNA036090AA

This is the factory-specified dual run capacitor for the Carrier PY3PNA036090AA packaged unit. The dual run capacitor serves a critical function: it stores and delivers the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. When this capacitor weakens or fails, you'll typically hear a persistent hum with no motor startup, notice the system tripping off on thermal overload shortly after startup, or experience complete failure to cool. OEM part numbers covered: P291-5053RS (primary dual run), P291-0403 (single run), and P291-1503 (single run). Note: P291-5053RS has been superseded — the current OEM equivalent is P291-5054RS (440V rated), which is a direct, code-approved upgrade.

  • Specs: 50+5 MFD (microfarad) | 370V rated (superseded by 440V P291-5054RS) | Round case | ±5% factory tolerance | Fits compressor (50 MFD) + condenser fan motor (5 MFD) terminals
  • OEM vs Generic: OEM capacitors are wound to exact Carrier factory tolerance, ensuring correct motor torque curves and thermal protection. Aftermarket units commonly run ±10% MFD deviation, which accelerates compressor wear and can void equipment warranties.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wire connections before disconnecting. Observe HERM, FAN, and COM terminal labels carefully.
  • Warranty & Shipping: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier PY3PNA036090AA packaged units. Cross-references: P291-5053RS, P291-5054RS, P291-0403, P291-1503, HC98JA051, 05706036. Always verify MFD rating and voltage against your unit's data plate before ordering. Our team is available to confirm fitment — order with confidence.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 50+5 MFD 370V — PY3PNA036090AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 50+5 MFD 370V — PY3PNA036090AA. 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 Dual Run Capacitor 50+5 MFD 370V — PY3PNA036090AA?
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?
