OEM Carrier Dual Run Capacitor 35+5 MFD & Single Run Capacitor 15 MFD 370V for Model PH2PNB024000AC

This listing covers the two factory-specified OEM run capacitors for the Carrier PH2PNB024000AC packaged heat pump unit: the P291-3553 Dual Run Capacitor (35+5 MFD 370V) and the P291-1503 Single Run Capacitor (15 MFD 370V). The dual run capacitor simultaneously supports the compressor (HERM terminal, 35 MFD) and condenser fan motor (FAN terminal, 5 MFD), while the single run capacitor provides dedicated start and run support for auxiliary motor loads. When either capacitor degrades, you'll experience symptoms ranging from a loud hum with no compressor start, a condenser fan that won't spin, or a system that short-cycles and trips on high-pressure lockout within minutes of startup.

  • Specs — Dual Run (P291-3553): 35+5 MFD (microfarad) | 370 VAC | Oval case | Terminals: HERM / C / FAN | Tested to 60,000 service hours | RoHS compliant | UL approved pressure-sensitive interrupter | ±5% capacitance tolerance
  • Specs — Single Run (P291-1503): 15 MFD | 370 VAC | Oval case | Non-PCB dielectric fluid | UL approved current interrupter | Multiple electrical terminals | RoHS compliant
  • OEM vs Generic: These are Totaline-branded OEM capacitors built to Carrier factory specification. Generic aftermarket capacitors often carry ±10% MFD tolerance vs. the OEM ±5%, leading to accelerated compressor and motor wear. Always match the MFD rating and use equal or higher voltage rating when replacing.
  • Install Difficulty: 2/5 — Discharge the capacitor fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Always photograph wiring connections before disconnecting. Note: P291-3553 has been superseded by P291-3554; P291-1503 has been superseded by P291-1504 — both are confirmed compatible replacements.
  • Warranty: 1-year OEM factory warranty. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Engineered for the Carrier PH2PNB024000AC packaged heat pump unit. 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 for peace of mind. In stock and ready to ship today.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual & Single Run Capacitor Kit 35+5/15 MFD 370V — PH2PNB0?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual & Single Run Capacitor Kit 35+5/15 MFD 370V — PH2PNB0. 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 & Single Run Capacitor Kit 35+5/15 MFD 370V — PH2PNB0?
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?
