OEM Carrier Single Run Capacitor Kit 4 MFD + 15 MFD 370V for Model PY3PEA048090NA

This OEM-matched single run capacitor kit contains both factory-specified capacitors for the Carrier PY3PEA048090NA packaged gas/electric unit: the P291-0403 (4 MFD 370V) for the condenser fan motor and the P291-1503 (15 MFD 370V) for the compressor. Each capacitor stores and delivers the precise electrical charge needed to start and sustain its respective motor. When either fails, symptoms include a humming outdoor unit that won't spin up, a compressor that short-cycles, or a tripped high-pressure limit — all leading to a no-cooling condition on a hot day.

• Specs: P291-0403 — 4 MFD (microfarad) | 370 VAC | Oval case | ±5% factory tolerance. P291-1503 — 15 MFD | 370 VAC | Oval case | ±5% factory tolerance. Both are Totaline/Carrier OEM Polypropylene Film construction, RoHS compliant.
• OEM vs Generic: Carrier Totaline capacitors are reliability-tested to 60,000 service hours per United Technologies application parameters and subjected to 100% electrical testing at the factory. Generic capacitors often carry ±10% MFD tolerance, accelerating motor wear and shortening compressor life.
• Install difficulty: 2/5 — Always discharge capacitors fully before handling terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance setting. Photograph all wiring before disconnecting. Replace both capacitors together to eliminate multiple service calls.
• Warranty: 1-year OEM factory warranty. Orders ship same business day from our warehouse. Compatible successor parts P291-0404 and P291-1504 may ship if OEM stock is fulfilled from updated revision.

Compatibility: This kit is engineered for the Carrier PY3PEA048090NA packaged gas/electric unit. Verify MFD rating and voltage on your unit's data plate before ordering — do not substitute a higher or lower MFD value. Have a question about fitment?
