OEM Carrier Single Run Capacitor (P291-0403 / P291-2503) for Model PY3PPA060115AA

This factory-original single run capacitor is the OEM-specified replacement for the Carrier PY3PPA060115AA 5-ton packaged gas/electric rooftop unit. A single run capacitor maintains the steady electrical charge required to keep the compressor or condenser fan motor running efficiently after startup. When this component weakens or fails, you'll notice symptoms such as hard starting, audible humming with no motor rotation, the system tripping on high pressure, or the unit short-cycling — all signs of capacitor degradation that worsen rapidly in summer heat loads.

  • OEM Part Numbers: P291-0403 (primary) | P291-2503 (alternate/superseded) — both are direct factory replacements for the Carrier PY3PPA060115AA packaged rooftop unit. Always verify MFD and voltage ratings on your unit's data plate before ordering.
  • OEM vs Generic: This is a genuine Carrier OEM capacitor held to factory-specified MFD tolerance (±3%). Aftermarket generics often run ±10% tolerance, which increases motor winding stress, accelerates compressor wear, and can void your equipment warranty.
  • Install Difficulty: 2/5 — Disconnect and lock out power before servicing. Discharge the capacitor fully using an insulated resistor or discharge tool before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before removal.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your unit back online fast.

Compatibility: Designed and factory-matched for the Carrier PY3PPA060115AA 5-ton packaged gas/electric rooftop unit. Cross-references OEM part numbers P291-0403 and P291-2503. Confirm capacitor MFD rating and voltage stamped on your existing unit's data plate before completing your order. Have a fitment question?

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PPA060115AA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3PPA060115AA. 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 PY3PPA060115AA?
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.
