OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PY4GNAB48090AA

This OEM Carrier dual run capacitor (part# P291-7054R) is the factory-specified replacement for the Carrier PY4GNAB48090AA packaged unit. Part of Carrier's Totaline capacitor series, it stores and releases the electrical charge needed to start and sustain both the compressor and condenser fan motor during every cooling cycle. When this capacitor fails, you'll typically notice a loud hum with no motor response, the system tripping on high-pressure lockout, or the condenser overheating and shutting down within minutes of startup.

  • Specs: 70+5 MFD (microfarad) | 440V rated | Round case | ¼" quick-disconnect terminals | 50/60 Hz | UL & CSA approved | –40°C to +70°C operating range
  • OEM vs Generic: This OEM Totaline capacitor is reliability-tested to 60,000 service hours per Carrier application parameters using high-grade metallized polypropylene film. Generic capacitors often carry ±10% MFD tolerances, accelerating compressor wear and shortening motor life.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals — stored charge can cause serious injury. Tools needed: ¼" nut driver, insulated needle-nose pliers, multimeter with capacitance mode. Photograph all wiring connections before removing the old unit.
  • Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct drop-in replacement for Carrier PY4GNAB48090AA packaged units. This part also replaces HC98KA071, P291-7053RS, and P291-7073RS. Always verify the MFD rating and voltage on your unit's data plate before ordering. Our team is available to confirm fitment — reach out before you buy if you have any questions.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 70+5 MFD 440V — PY4GNAB48090AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 70+5 MFD 440V — PY4GNAB48090AA. 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 440V — PY4GNAB48090AA?
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?
