OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V for Model PH15NA048000BAAA

This OEM dual run capacitor (part# P291-7073RS, with associated start capacitor P281-1766) is the factory-specified replacement for the Carrier PH15NA048000BAAA heat pump condenser. The dual run capacitor stores and releases the electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. When it fails, you'll typically notice a low hum with no motor movement, the system short-cycling within minutes of startup, or the compressor running while the fan motor stops — all signs of imminent system damage if left unaddressed.

  • Specs: 70+7.5 MFD (microfarad) | 370V rated | Round case | 2.5" diameter | 0.250"×0.032" QC male tabs | 50/60 Hz | ±6% tolerance | 10,000 AFC safety rated
  • OEM vs Generic: This is a genuine OEM Carrier Totaline capacitor, reliability-tested to 60,000 service hours per United Technologies application parameters. Generic capacitors commonly run at ±10% MFD tolerance, accelerating motor wear and reducing compressor lifespan. OEM spec ensures your system runs as designed.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wire connections before disconnecting. Match MFD and voltage ratings exactly to the data plate on your unit before installing.
  • Warranty & Shipping: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.

Compatibility: Engineered for Carrier model PH15NA048000BAAA heat pump condensers. OEM part numbers P291-7073RS and P281-1766. Note: P291-7073RS has been superseded by P291-7074R (440V rated upgrade) — our listing includes the correct current OEM equivalent. Always verify the MFD and voltage rating on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you buy — contact us before checkout.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V — PH15NA048000BAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V — PH15NA048000BAAA. 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+7.5 MFD 370V — PH15NA048000BAAA?
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?
