OEM Carrier Single Run Capacitor 15 MFD 370V for Model PY1REA048074AAWA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1REA048074AAWA system. Supplied under Carrier/Totaline OEM part numbers P291-1503 and P291-0403, this oval-case run capacitor maintains the continuous phase-shifted current that keeps your condenser fan motor or compressor running smoothly at rated efficiency. When a run capacitor degrades or fails, you'll notice symptoms such as the motor struggling to start, humming without spinning, short-cycling, or the unit tripping on high-pressure lockout due to inadequate airflow or compression.

  • Specs: 15 MFD (microfarad) | 370V rated | Oval case | Factory-matched ±5% capacitance tolerance | Metallized polypropylene film dielectric | RoHS compliant
  • OEM vs Generic: OEM Carrier/Totaline capacitors are reliability-tested to 60,000 service hours and subjected to 100% electrical testing at the factory. Generic units often lack tight MFD tolerance control, accelerating motor winding wear and shortening equipment life.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before removing terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings on the unit's data plate before installing.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier model PY1REA048074AAWA. Part numbers P291-1503 and P291-0403 are Carrier/Totaline factory authorized parts. Note: P291-1503 has been superseded — this listing ships the current authorized equivalent. Always verify MFD rating and voltage on your unit's data plate before ordering. Need help confirming fitment? Our HVAC parts team verifies compatibility before you buy — order with confidence and get same-day shipping.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1REA048074AAWA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY1REA048074AAWA. 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 PY1REA048074AAWA?
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.
