OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PEB048130NBAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1PEB048130NBAA packaged unit. The run capacitor remains in the circuit continuously during motor operation, stabilizing voltage and ensuring the fan motor runs efficiently. When it degrades or fails, you'll typically notice a humming sound with no motor movement, the unit blowing warm air, short cycling, or the system failing to start altogether. Visible swelling or oil residue on the capacitor body is also a clear sign of failure.

  • Specs: 4 MFD (microfarad) | 370 VAC | Oval case | 50/60 Hz | OEM part numbers: P291-0403 (4 MFD 370V), P291-1003 (10 MFD 370V), P291-1503 (15 MFD 370V) — select the MFD rating that matches your unit's data plate
  • OEM vs Generic: This is a genuine Totaline/Carrier OEM capacitor tested to 60,000 service hours with 100% electrical testing at the factory and UL-approved pressure-sensitive interrupter for safe failure. Generic aftermarket units often carry ±10% MFD tolerance versus OEM precision, accelerating motor wear over time.
  • Install difficulty: 2/5 — Shut off power at the disconnect box and wait 5 minutes for residual charge to bleed before touching any terminals. Tools needed: flathead or 1/4" nut driver, needle-nose pliers, multimeter (to verify discharge). Always photograph existing wiring before disconnecting terminals. Match the MFD and voltage rating exactly to the data plate.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY1PEB048130NBAA packaged unit. Three OEM part numbers cover different MFD ratings used across the PY1PEB series — verify your unit's capacitor MFD rating on the equipment data plate or existing capacitor label before selecting. Cross-references include GE/Genteq 97F5704, HC90AA004, HC91CA004, and HC90AB004. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — ships today.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1PEB048130NBAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY1PEB048130NBAA. 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 PY1PEB048130NBAA?
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.
