OEM Carrier Single Run Capacitor 15 MFD 370V for Model PH2PPB042000AA

This is the factory-specified OEM single run capacitor for the Carrier PH2PPB042000AA heat pump system, carrying OEM part number P291-1503 (superseded by P291-1504). The run capacitor provides the continuous phase-shifted current required to keep the compressor motor running efficiently after start-up. When this capacitor degrades or fails, you'll typically experience symptoms such as a humming condenser with no compressor start, intermittent hard-starting, increased amp draw, or a complete no-cool condition as the compressor trips on thermal overload.

  • Specs: 15 MFD (microfarad) | 370V rated | Oval case form factor | ±5% factory tolerance | OEM part# P291-1503 / P291-1504
  • OEM vs Generic: This OEM Carrier capacitor is manufactured to exact factory tolerances, ensuring proper compressor motor protection and longevity. Generic capacitors often carry a wider ±10% MFD tolerance, which can accelerate motor wear, reduce efficiency, and shorten compressor life.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify MFD before installation). Photograph all wiring connections before disconnecting the old unit.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse when ordered by 3 PM local time.

Compatibility: Designed as the direct OEM replacement for Carrier model PH2PPB042000AA heat pump systems. Always verify the MFD rating and voltage specification on your unit's data plate before ordering. Note that P291-1503 has been superseded by P291-1504 (upgraded to 440V) — both are fully compatible replacements. Our fitment team is available to confirm compatibility before you order.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH2PPB042000AA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH2PPB042000AA. 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 PH2PPB042000AA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
