OEM Carrier Dual Run Capacitor 70+5 MFD 370/440V for Model PY4GNAA48090AA

This OEM dual run capacitor (part number P291-7053RS) is the factory-specified replacement for the Carrier PY4GNAA48090AA packaged unit. The dual run capacitor simultaneously supports both the compressor and the condenser fan motor — storing and releasing the electrical charge needed to start each component and keep them running efficiently. When this capacitor fails, common symptoms include a loud humming with no motor movement, a system that trips on high-pressure lockout, short-cycling within the first few minutes of operation, or a condenser fan that spins only when manually assisted.

  • Specs: 70+5 MFD (microfarad) | 370/440V dual-rated | Round case | ±3% factory tolerance | CBB65 rated
  • OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances. Aftermarket units commonly run ±10% MFD drift, which accelerates compressor wear, shortens fan motor life, and can void equipment warranties.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty. Orders placed before 3 PM ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PY4GNAA48090AA packaged unit. Note that P291-7053RS has been superseded by P291-7054R — both are fulfilled as the current OEM specification. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering. Have questions about fitment? Our HVAC parts specialists verify compatibility before your order ships.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 70+5 MFD 370/440V — PY4GNAA48090AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 70+5 MFD 370/440V — PY4GNAA48090AA. 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 70+5 MFD 370/440V — PY4GNAA48090AA?
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?
