OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PNA060115NA

This is the factory-specified OEM single run capacitor for the Carrier PY3PNA060115NA packaged or split-system unit. The run capacitor remains energized throughout the entire operating cycle, continuously supplying the phase-shifted current that allows the fan motor or compressor motor to run efficiently. When this capacitor weakens or fails, you'll notice symptoms like a loud hum with no motor movement, a condenser fan that spins only when manually assisted, warm air output despite the compressor running, or the unit short-cycling under load. Replacing it promptly prevents accelerated motor wear and compressor damage.

  • Specs: 4 MFD (microfarad) ± 5% | 370 VAC rated | Oval case form factor | 50/60 Hz | Factory-matched Carrier OEM tolerance
  • OEM vs Generic: This genuine Carrier / Totaline OEM capacitor is manufactured to exact MFD tolerance and subjected to 100% electrical testing before shipment. Generic aftermarket capacitors frequently ship at ±10% tolerance, which causes motors to draw excess current and shortens compressor life.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker. Allow 5 minutes for residual charge to dissipate before touching any terminals — capacitors store lethal voltage even after shutdown. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removing the old capacitor.
  • Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Engineered as a direct OEM drop-in replacement for Carrier model PY3PNA060115NA. Also cross-references OEM part numbers P291-2503, HC90AA004, HC91CA004, and HC90AB004. Always verify the MFD rating and voltage on your unit's data plate or existing capacitor label before ordering. Have fitment questions?

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PNA060115NA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3PNA060115NA. 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 PY3PNA060115NA?
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.
