OEM Carrier Single Run Capacitor Kit 4 MFD + 15 MFD 370V for Model PY2PPB048130AB

This factory-matched OEM single run capacitor kit includes both the P291-0403 (4 MFD 370V) and P291-1503 (15 MFD 370V) oval run capacitors — the exact pair specified for the Carrier PY2PPB048130AB packaged unit. These capacitors maintain the steady electrical charge that keeps the compressor motor and condenser fan motor running efficiently after start-up. When either capacitor degrades or fails, you'll typically notice the system humming without fully starting, motors running hot, the unit short-cycling, or a complete no-cool condition. Replacing both at the same time is industry best practice — if one has failed, the other is likely near end of life.

• Specs: P291-0403 — 4 MFD (microfarad) | 370V | Oval case | Single run | P291-1503 — 15 MFD | 370V | Oval case | Single run | ±5% factory tolerance | 60 Hz rated
• OEM vs Generic: These are genuine Carrier Totaline-series capacitors engineered to meet factory reliability standards. OEM units are tested to 60,000+ service hours and subject to 100% electrical testing. Generic capacitors often carry wider MFD tolerances that accelerate motor wear and reduce system efficiency.
• Install difficulty: 2/5 — Always discharge capacitors before handling — they retain lethal voltage after power is cut. Tools needed: insulated screwdriver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Each capacitor connects to its respective motor terminal; do not swap them.
• Warranty: 1-year OEM factory warranty on both capacitors. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: This kit is specifically matched to the Carrier PY2PPB048130AB packaged unit. Always verify the MFD and voltage ratings against your unit's data plate before installing. Cross-reference part numbers P291-0403 and P291-1503 (or their current successors P291-0404 and P291-1504) to confirm correct fit. Have questions about fitment?
