OEM Carrier Dual Run Capacitor 50+5 MFD 440V for Model PH10JA048000ABAA

This OEM dual run capacitor (part# P291-5054RS) is the factory-specified replacement for the Carrier PH10JA048000ABAA heat pump. The dual run capacitor stores and releases the electrical charge needed to start and continuously run both the compressor and the condenser fan motor simultaneously. When this component fails, symptoms typically include a loud hum with no compressor or fan startup, the system short-cycling within the first few minutes of operation, or a complete failure of the outdoor unit to respond — all of which can quickly cascade into compressor damage if left unaddressed.

  • Specs: 50+5 MFD (microfarad) | 370/440V dual-rated | Round case | ±3% factory tolerance | 50/60 Hz | RoHS compliant | UL approved
  • OEM vs Generic: This is the genuine Carrier/Totaline OEM part, tested to 60,000 service hours. Generic capacitors often carry a ±10% MFD tolerance, increasing stress on the compressor windings and shortening motor life significantly.
  • Install difficulty: 2/5 — Always discharge the capacitor before handling terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Three terminals labeled HERM, FAN, and C (common).
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH10JA048000ABAA heat pump. Also replaces superseded part numbers HC98CA050, HC98JA051, P291-5053R, and P291-5053RS. Always verify the MFD rating and voltage on your unit's data plate before ordering. Have a fitment question? Our HVAC parts specialists confirm compatibility before you buy — order with confidence and get your system back up and running today.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 50+5 MFD 440V — PH10JA048000ABAA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 50+5 MFD 440V — PH10JA048000ABAA. 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 50+5 MFD 440V — PH10JA048000ABAA?
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?
