OEM Carrier Dual Run Capacitor 55+5 MFD 370V for Model PH1RJA048000AAWB

This OEM dual run capacitor is the factory-specified replacement for the Carrier PH1RJA048000AAWB heat pump system. Sourced to original Carrier specification under part numbers P291-5553RS (original) and its current OEM successor P291-5554RS, this capacitor stores and releases the precise electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. When a dual run capacitor begins to fail, symptoms include a tell-tale hum at startup with no motor spin, hard-starting that trips the breaker, the outdoor fan running while the compressor stays locked out, or the unit short-cycling within minutes of startup on a hot day.

  • Specs: 55+5 MFD (microfarad) | 370V rated (440V-rated successor P291-5554RS is a direct upgrade) | Round case | ±5% factory tolerance | 50/60 Hz
  • OEM vs Generic: OEM capacitors are manufactured to Carrier's exact tolerance specifications. Generic aftermarket units commonly run ±10% MFD variance, which accelerates motor winding stress, shortens compressor life, and can void equipment warranties.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling — stored charge can cause serious injury even with power off. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our climate-controlled warehouse. Also includes secondary part P291-1503 (15 MFD 370V single run capacitor, successor P291-1504) for full capacitor kit compatibility.

Compatibility: Designed for the Carrier PH1RJA048000AAWB heat pump condenser. OEM part numbers P291-5553RS and P291-1503 are both factory-discontinued; P291-5554RS (55+5 MFD 440V) and P291-1504 (15 MFD 440V) are the current OEM-authorized successors and direct drop-in replacements. Always verify MFD and voltage ratings against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 55+5 MFD 370V — PH1RJA048000AAWB?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 55+5 MFD 370V — PH1RJA048000AAWB. 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 55+5 MFD 370V — PH1RJA048000AAWB?
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?
