OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PEB042060AA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY2PEB042060AA packaged unit. The run capacitor stays in the circuit continuously while the motor operates, providing the phase-shifted electrical charge needed to keep the fan motor running efficiently and smoothly. When it degrades or fails, symptoms typically include a humming condenser or blower motor that won't spin, the system short-cycling within seconds of startup, or the unit running warm due to a struggling motor drawing excess amperage.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | OEM part numbers: P291-0403 (primary), P291-1503 (secondary) | Replaces legacy P/N 97F5704 | Factory-matched tolerance
• OEM vs Generic: This OEM capacitor is built to Carrier's exact factory specification, including high-grade metallized polypropylene film dielectric and a UL-approved pressure-sensitive interrupter for safe fail-open protection. Generic capacitors often run at wider MFD tolerances, accelerating motor wear and risking premature compressor failure.
• Install difficulty: 2/5 — Always shut off power at the disconnect and wait 5 minutes for the capacitor to fully discharge before touching any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier PY2PEB042060AA packaged unit. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering — substituting a higher voltage (440V) unit of the same MFD is acceptable, but MFD must match exactly.
