OEM Carrier Single Run Capacitor Set (4 MFD & 15 MFD 370V) for Model PY3PPA036060AA

This factory-matched OEM single run capacitor set includes both the P291-0403 (4 MFD 370V) and P291-1503 (15 MFD 370V) oval capacitors — the two Carrier-specified single run capacitors for the PY3PPA036060AA packaged heat pump unit. Unlike a dual-run capacitor, this unit uses two discrete oval single run capacitors: one dedicated to the condenser fan motor and one to the compressor. Each capacitor stores and releases the electrical charge required to start and sustain its respective motor during every heating and cooling cycle. When one fails, you'll typically hear a persistent hum with no motor movement, notice the system short-cycling, or find the unit not cooling or heating at all.

  • Specs — P291-0403: 4 MFD (microfarad) | 370 VAC | Oval case | 50/60 Hz | Single run | Factory ±5% tolerance
  • Specs — P291-1503: 15 MFD (microfarad) | 370 VAC | Oval case | 50/60 Hz | Single run | Factory ±5% tolerance
  • OEM vs Generic: OEM Carrier/Totaline capacitors are manufactured to exact factory tolerances and subjected to 100% electrical testing. Generic capacitors often run wider tolerance bands, accelerating motor wear and increasing compressor strain over time.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and allow 5 minutes for capacitors to self-discharge before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before removal. Replace one capacitor at a time to avoid wiring errors.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model PY3PPA036060AA packaged heat pump units. Always verify MFD and voltage ratings against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor Kit 4+15 MFD 370V — PY3PPA036060AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor Kit 4+15 MFD 370V — PY3PPA036060AA. 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 OEM Carrier Single Run Capacitor Kit 4+15 MFD 370V — PY3PPA036060AA?
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?
