OEM Carrier Single Run Capacitor for Model PY1PPB048115NBAA

This is the factory-specified OEM single run capacitor for the Carrier PY1PPB048115NBAA packaged unit. A single run capacitor maintains the continuous phase shift needed to keep the condenser fan motor or compressor running efficiently after startup. When this capacitor weakens or fails, common symptoms include a loud hum at startup with no motor movement, intermittent short-cycling, increased energy consumption, or a complete failure to cool. Replacing it promptly prevents downstream damage to the compressor and fan motor — two of the most expensive components in any packaged system.

  • OEM Part Numbers: P291-0403 (primary) | P291-1503 (alternate/superseded) — both are factory-authorized replacements for this unit. Verify your existing capacitor's MFD and voltage ratings against your unit's data plate before installation.
  • OEM vs Generic: OEM Carrier capacitors are manufactured to exact factory tolerances (±3% MFD), ensuring proper motor protection and longevity. Generic alternatives often carry ±10% tolerance, which can accelerate motor winding wear and shorten compressor life significantly.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use a 20,000-ohm resistor or insulated screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance setting. Photograph all wiring connections before disconnecting.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for the Carrier PY1PPB048115NBAA packaged unit. Always confirm the MFD rating and voltage stamped on your existing capacitor match this part. Not sure? Contact our technical team — we verify fitment before you order so you never receive the wrong part.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1PPB048115NBAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY1PPB048115NBAA. 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 PY1PPB048115NBAA?
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.
