OEM Carrier Dual Run Capacitor 70+5 MFD 370V for Model PY3GNA048090NA

This OEM-spec dual run capacitor (part number P291-7053RS) is the factory-matched replacement for Carrier model PY3GNA048090NA packaged HVAC systems. The dual run capacitor stores and delivers the electrical charge required to start and sustain both the compressor motor and the condenser fan motor simultaneously from a single round canister. When this capacitor weakens or fails, common symptoms include a loud humming sound with no motor startup, a system that trips on high-pressure lockout within minutes of starting, a condenser fan that spins slowly or not at all, or a compressor that draws high amperage and overheats. Replacing this capacitor promptly protects your compressor — the most expensive component in the system — from premature failure.

• Specs: 70+5 MFD (microfarad) | 370/440V dual-rated | Round case | ±5% factory tolerance | 50/60 Hz | Replaces P291-7053RS, P291-7054R, C3705R, 27L633, HC98JA071
• OEM vs Generic: OEM-spec capacitors are wound and sealed to exact factory tolerance. Off-brand capacitors frequently drift beyond ±10% MFD under heat load, accelerating compressor wear and shortening service life — particularly critical on high-demand 4-ton packaged units like the PY3GNA048090NA.
• Install difficulty: 2/5 — Always discharge the capacitor terminals with an insulated resistor tool before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode to verify before install). Photograph all wiring connections before disconnecting the old capacitor. Swap terminals one at a time to avoid miswiring HERM, FAN, and COMMON posts.
• Warranty: 1-year replacement warranty. In-stock and ships same business day from our warehouse.

Compatibility: Verified fit for Carrier model PY3GNA048090NA packaged gas/electric units. Also cross-references Bryant and Payne models sharing the 70+5 MFD 370V specification. Always confirm MFD rating and voltage on your unit's data plate or wiring diagram before ordering. Our parts specialists are available to verify fitment — contact us before you order if you have any questions.
