OEM Carrier Single Run Capacitor Kit 4 MFD & 15 MFD 370V for Model PY2PEB042060NB

This factory-authorized OEM single run capacitor kit includes both the P291-0403 (4 MFD 370V) and P291-1503 (15 MFD 370V) oval run capacitors — the exact Totaline/Carrier-specified replacements for the PY2PEB042060NB packaged unit. Run capacitors remain energized throughout motor operation, stabilizing voltage and sustaining efficient rotation of the fan and compressor motors. When a run capacitor degrades or fails, symptoms include a humming or buzzing noise on startup, the system blowing warm air, short-cycling, or a complete no-start condition on one or both motor circuits.

• Specs: P291-0403 — 4 MFD | 370 VAC | Oval shape | 1.2" W × 2.8" H  |  P291-1503 — 15 MFD | 370 VAC | Oval shape | 1.2" W × 3.9" H | Both rated 50/60 Hz | ±5% factory tolerance | RoHS compliant | UL recognized
• OEM vs Generic: These are genuine Totaline/Carrier OEM capacitors — factory-tested to 60,000 service hours with high-grade metallized polypropylene film dielectric. Generic capacitors frequently ship at ±10% MFD tolerance, increasing thermal stress on windings and shortening motor life.
• Install difficulty: 2/5 — Shut off power at the disconnect and allow 5 minutes for the capacitors to self-discharge before touching any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph terminal wiring before disconnecting. Swap one capacitor at a time to avoid wiring errors.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: This kit is factory-matched to Carrier model PY2PEB042060NB. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering — do not substitute a higher or lower MFD value. Questions about fitment?
