OEM Carrier Single Run Capacitor Kit 4 MFD & 15 MFD 370V for Model PY1PNB060130AAAA

This OEM-matched single run capacitor kit includes both the P291-0403 (4 MFD 370V) and P291-1503 (15 MFD 370V) oval run capacitors — the factory-specified components for the Carrier PY1PNB060130AAAA packaged unit. Each capacitor stores and releases the precise electrical charge required to start and sustain its respective motor. When either capacitor degrades, you'll typically notice a humming unit that won't start, a motor that kicks off within minutes of startup, or a tripped breaker caused by a locked-rotor condition. Replacing both at the same service call is the industry best practice for preventing a repeat call-back.

• Specs: P291-0403 — 4 MFD (microfarad) | 370V | Oval case | Single run  /  P291-1503 — 15 MFD | 370V | Oval case | Single run | Factory-matched ±5% tolerance | UL Approved | RoHS Compliant
• OEM vs Generic: Carrier Totaline OEM capacitors are reliability-tested to 60,000 service hours using high-grade metallized polypropylene film. Generic alternatives often run looser tolerances, accelerating motor wear and voiding equipment warranties.
• Install difficulty: 2/5 — Always discharge capacitors before handling — stored charge can cause serious injury. Tools needed: 1/4" nut driver, insulated screwdriver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting terminals. Verify MFD and voltage ratings against the unit data plate before installation.
• Warranty & Shipping: 1-year OEM factory warranty. Ships same business day from our warehouse. Both capacitors included in one order — no separate sourcing required.

Compatibility: This kit is engineered for the Carrier PY1PNB060130AAAA packaged unit. Note: P291-1503 has been superseded — we ship the current OEM-equivalent replacement (P291-1504, 440V/15 MFD) where the original is unavailable, which is fully backward-compatible. Always verify MFD and voltage ratings on your unit's data plate before installation. Questions about fitment? Our HVAC parts specialists confirm compatibility before you order — order with confidence.
