OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PNB048130AB

This is the factory-specified OEM single run capacitor for the Carrier PY2PNB048130AB packaged gas/electric unit. The run capacitor stays in the motor circuit continuously during operation, storing and releasing electrical energy to keep the condenser fan motor spinning efficiently. When it fails, symptoms range from a buzzing or humming noise with no motor movement, to a fan that starts slowly and shuts the unit down on thermal overload, to a complete no-cooling condition. Replacing it promptly protects the motor from burnout caused by running without proper capacitance.

  • Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | OEM part numbers: P291-0403 (primary), P291-1503 (alternate/superseded) | Replaces legacy P/N 97F5704 | Factory ±5% tolerance
  • OEM vs Generic: This is a genuine Carrier OEM capacitor built to exact factory tolerances. Generic aftermarket capacitors often carry a wide ±10% MFD variance, which can accelerate motor winding wear and shorten equipment life — particularly important for packaged rooftop and ground-set units exposed to high ambient temperatures.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and wait 5 minutes for residual charge to dissipate before touching terminals. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring terminals before disconnecting leads. The oval case mounts with a single bracket screw in the control compartment.
  • Warranty & Shipping: 1-year OEM factory warranty against defects. In stock at NationalHVACParts.com — ships same business day when ordered before cutoff. Arrives in protective anti-static packaging to prevent transit damage.

Compatibility: Confirmed fit for Carrier model PY2PNB048130AB packaged gas/electric unit (4-ton, 130 MBH heat). Always verify the MFD rating and voltage on your unit's capacitor data label or wiring diagram before ordering. If you need help confirming fitment for a related Bryant or Payne packaged unit variant, our parts team verifies compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor 4 MFD 370V — PY2PNB048130AB?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor 4 MFD 370V — PY2PNB048130AB. 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 Single Run Capacitor 4 MFD 370V — PY2PNB048130AB?
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.
