OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PNA060115AA

This is the factory-specified OEM single run capacitor for the Carrier PY3PNA060115AA Performance Series packaged gas/electric unit. The run capacitor sustains the phase-shifted voltage required to keep the condenser fan motor spinning efficiently throughout every cooling cycle. When it weakens or fails, the motor loses torque — symptoms include a loud hum with no fan rotation, intermittent shutdowns on hot days, or the unit tripping the high-pressure limit. Left unaddressed, a failed run capacitor forces the motor to draw locked-rotor amperage, rapidly burning out the motor windings.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% factory tolerance | 50/60 Hz | Replaces P/N 97F5704, HC90AA004, HC91CA004, HC90AB004. Also cross-references secondary OEM part P291-2503 for blower circuit applications on this model — verify your unit's wiring diagram before ordering.
• OEM vs Generic: This genuine Carrier/Totaline capacitor is manufactured to exact factory tolerances and subjected to 100% electrical testing before packaging. Generic aftermarket capacitors are typically rated at a looser ±10% MFD tolerance, which accelerates motor wear and reduces compressor longevity over time.
• Install Difficulty: 2/5 — Locate and switch off the unit's disconnect and wait a minimum of 5 minutes for the capacitor to discharge fully before touching any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter capable of reading capacitance. Photograph all wiring connections before removing the old capacitor. Match MFD and voltage ratings exactly to the data plate on your unit.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PNA060115AA Performance Series 5-ton packaged gas/electric unit. Always verify the MFD rating and voltage stamped on your existing capacitor against your unit's data plate before ordering. Our team is available to confirm fitment prior to purchase — reach out before you order if you have any questions.
