OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PPB048130NBAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1PPB048130NBAA packaged unit. The run capacitor maintains a continuous phase-shifted current to keep the fan motor or compressor running efficiently after startup. When this component fails, you'll typically notice the motor humming without turning over, the system tripping on thermal overload shortly after startup, or the unit failing to cool or heat entirely — all classic signs of capacitor failure.

  • Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | Factory-matched ±5% tolerance | OEM Part Numbers: P291-0403 / P291-1503 (superseded by P291-0404)
  • OEM vs Generic: This OEM Carrier/Totaline capacitor is reliability-tested to 60,000 service hours and subjected to 100% electrical testing at the factory. Generic capacitors often carry wider MFD tolerances (±10%), which can accelerate motor wear and shorten equipment life.
  • Install difficulty: 1/5 — One of the easiest HVAC repairs. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, multimeter (to verify discharge). Always discharge the capacitor fully before handling terminals and photograph wiring before disconnecting.
  • Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Fits Carrier model PY1PPB048130NBAA packaged unit. Verify the MFD rating and voltage on your unit's data plate before ordering. This part also cross-references OEM numbers HC90AA004, HC91CA004, and HC90AB004. Have questions about fitment? Our HVAC parts team verifies compatibility before you order — reach out before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1PPB048130NBAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY1PPB048130NBAA. 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 PY1PPB048130NBAA?
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.
