OEM Carrier Single Run Capacitor 4 / 10 / 15 MFD 370V for Model PY1PPB060115AAAA

This is the factory-specified OEM single run capacitor for the Carrier PY1PPB060115AAAA packaged unit. Single run capacitors remain in the electrical circuit continuously during compressor and fan motor operation, storing and releasing the charge needed to sustain efficient motor performance. When a run capacitor degrades or fails, you'll typically notice symptoms such as a humming or buzzing noise with no motor start, the system short-cycling within minutes, warm air being delivered instead of conditioned air, or a visible bulge on the capacitor can itself. Replacing the failed capacitor is one of the most common and cost-effective HVAC repairs available.

• Specs: Available in 4 MFD (P291-0403), 10 MFD (P291-1003), and 15 MFD (P291-1503) | Voltage: 370 VAC | Style: Oval | 50/60 Hz compatible | Verify your unit's data plate for the exact MFD rating before ordering
• OEM vs Generic: These Carrier Totaline-series capacitors are reliability-tested to 60,000 service hours and subjected to 100% electrical testing at the factory. Generic capacitors often carry a ±10% MFD tolerance versus the tighter OEM spec, which can accelerate motor wear, reduce efficiency, and shorten compressor life — particularly in high-duty-cycle packaged units like the PY1PPB060115AAAA.
• Install Difficulty: 2/5 — Always shut off power at the disconnect and breaker before servicing. Allow 5 minutes for residual charge to dissipate, then use a screwdriver handle or insulated resistor to safely discharge remaining voltage. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring before disconnecting terminals.
• Warranty & Shipping: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Fits Carrier model PY1PPB060115AAAA packaged gas/electric unit. Also cross-references Carrier/Bryant parts HC90AA004, HC91CA004, HC91CA010, HC91CL010. Always confirm the MFD rating printed on your old capacitor's label before selecting your replacement. Questions about fitment?
