OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PEB036060AAAA

This is the factory-specified OEM single run capacitor for the Carrier PY1PEB036060AAAA packaged unit. Rated at 4 MFD (microfarad) at 370 VAC, this oval-case run capacitor maintains a continuous phase-shifted current to keep the fan motor or compressor running at peak efficiency after startup. When this capacitor degrades or fails, you'll typically observe the unit humming without the motor spinning, intermittent short-cycling, overheating, or a complete no-start condition — all signs that this inexpensive part needs immediate replacement before secondary motor damage occurs.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case form factor | OEM part numbers: P291-0403 / P291-1503 | ±5% capacitance tolerance | 50/60 Hz compatible
• OEM vs Generic: This OEM-spec capacitor is built with high-grade metallized polypropylene film and subjected to 100% electrical testing before leaving the factory — ensuring it meets the exact tolerances your Carrier unit was designed around. Generic alternatives often carry ±10% tolerance, which can accelerate motor wear over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead or nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph the existing wiring connections before disconnecting. The oval case clips into a bracket with a single retention strap.
• Warranty & Shipping: 1-year OEM warranty against manufacturing defects. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY1PEB036060AAAA packaged unit. Also supersedes legacy part numbers HC90AA004, HC91CA004, and HC90AB004. Always verify the MFD rating and voltage on your unit's data plate before ordering — the voltage rating must match or exceed the original. Our team is available to verify fitment before you buy.
