OEM Carrier Dual Run Capacitor 45+5 MFD 440V for Model PY1RJA048115AAWB

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY1RJA048115AAWB packaged unit. Working in tandem with both the compressor and condenser fan motor, the dual run capacitor stores and releases the electrical charge needed to start and sustain motor operation. When it fails, symptoms typically include a humming compressor that won't start, a fan motor that spins slowly or not at all, or a unit that short-cycles and trips on high-pressure lockout. Catching and replacing a weak capacitor early prevents far more costly compressor damage down the road.

  • Specs: 45+5 MFD (microfarad) | 440V rated | Round case | ±6% factory tolerance | 50/60 Hz | Castor oil protected, no-PCB construction | OEM Part Number: P291-4554RS (also cross-references HC30GB230 capacitor assembly, P291-0403, P291-1503)
  • OEM vs Generic: This is a genuine Carrier OEM capacitor meeting exact factory ±6% MFD tolerance. Generic capacitors often drift to ±10% or worse over time, accelerating wear on the compressor and condenser fan motor and voiding equipment warranties.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. The dual run capacitor has three terminals labeled HERM (compressor), FAN, and COM (common).
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse on all in-stock orders.

Compatibility: Designed for the Carrier PY1RJA048115AAWB packaged unit. Cross-references OEM part numbers HC30GB230 (draft inducer motor capacitor assembly), P291-4554RS (dual run), P291-0403, and P291-1503 (single run). Always verify MFD rating and voltage on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you buy — order with confidence.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 440V — PY1RJA048115AAWB?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 440V — PY1RJA048115AAWB. 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 45+5 MFD 440V — PY1RJA048115AAWB?
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.
