OEM Carrier Dual Run Capacitor 40+5 MFD 370V for Model PY1PNA036120ACBA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY1PNA036120ACBA packaged unit. Sourced under Carrier OEM part numbers P291-4053 and superseded by P291-4054RS, this capacitor stores and releases the electrical energy that starts and sustains both the compressor and condenser fan motor simultaneously. When it fails, symptoms include a distinct humming sound with no motor rotation, the system short-cycling within the first few minutes of operation, or the compressor running while the condenser fan sits completely still — all signs of imminent compressor damage if left unaddressed.

• Specs: 40+5 MFD (microfarad) | 370V rated | Oval case | ±6% tolerance | 50/60 Hz | Castor oil protected | AFC 10,000 | OEM part numbers: P291-4053, P291-4054RS (current supersession)
• OEM vs Generic: This is a genuine Carrier OEM capacitor sourced to exact factory specifications. Generic off-brand capacitors often carry ±10% MFD tolerance versus the OEM ±6%, accelerating compressor wear and shortening overall system life on your PY1PNA036120ACBA unit.
• Install difficulty: 2/5 — Always shut off power at the disconnect and discharge the capacitor terminals with an insulated resistor before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit. Replace like-for-like: verify MFD and voltage on your data plate before installation.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your Carrier unit running again fast.
