OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PEA048130AA

This is the genuine OEM single run capacitor factory-specified for the Carrier PY3PEA048130AA heat pump system. The run capacitor stores and continuously releases electrical energy to keep the condenser fan motor or compressor running at peak efficiency throughout every cycle. When it degrades or fails, you'll typically notice a humming or buzzing sound with no motor movement, the unit blowing warm air, short-cycling, or a complete no-start condition. Replacing this capacitor with the correct OEM part restores factory-spec performance and protects downstream motor components from overload stress.

  • Specs: 4 MFD (microfarad) ±5% tolerance | 370 VAC rated | Oval style case | OEM Part Numbers: P291-0403 (primary), P291-1503 (secondary/variant) | Replaces legacy P/N 97F5704
  • OEM vs Generic: This factory-original Carrier capacitor is manufactured to exact MFD and voltage tolerances. Generic capacitors often carry a ±10% MFD variance, which accelerates motor winding wear and can shorten compressor life — particularly critical on 4-ton heat pump platforms like the PY3PEA048130AA.
  • Install Difficulty: 2/5 — Discharge the capacitor fully before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring connections before removal. Verify MFD and voltage against your unit's data plate before installation.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for Carrier model PY3PEA048130AA. Cross-references OEM part numbers P291-0403 and P291-1503. Always confirm the MFD rating and voltage on your existing capacitor's label before ordering. Our fitment team is available to verify compatibility before you purchase — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PEA048130AA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3PEA048130AA. 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 PY3PEA048130AA?
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.
