OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PH1PNA042000ABBA

This OEM dual run capacitor (part number P291-4054) is the factory-specified replacement for the Carrier PH1PNA042000ABBA split-system air conditioner. The dual run capacitor serves a critical role: it stores and delivers the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously — all within a single compact housing. When this capacitor weakens or fails, you'll typically notice a persistent hum with no motor movement, the system short-cycling within the first few minutes of operation, or the condenser fan spinning freely by hand but failing to self-start under power.

  • Specs: 40+5 MFD (microfarad) | 440V rated | Oval case | ±6% factory tolerance | 50/60 Hz rated | UL recognized
  • OEM vs Generic: This is a genuine Carrier OEM capacitor built to exact factory tolerances. Generic aftermarket capacitors commonly carry a looser ±10% MFD tolerance, which places additional strain on the compressor windings and fan motor bearings over time — accelerating wear and shortening system life.
  • Install Difficulty: 2/5 — A straightforward DIY repair for anyone comfortable working around high-voltage components. Before touching any terminals, discharge the capacitor using an insulated resistor or discharge tool. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter for verification. Always photograph all wiring connections before disconnecting.
  • Warranty: Backed by a 1-year OEM manufacturer's warranty. In-stock orders ship same business day from our warehouse — get your system cooling again fast.

Compatibility: Designed as the direct OEM replacement for the Carrier PH1PNA042000ABBA condensing unit. Always verify the MFD rating, voltage, and capacitor shape on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you buy — just reach out.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 40+5 MFD 440V — PH1PNA042000ABBA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 40+5 MFD 440V — PH1PNA042000ABBA. 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 40+5 MFD 440V — PH1PNA042000ABBA?
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?
