Run capacitors store and release an electrical charge to keep PSC motors spinning efficiently at steady-state operation. When one or both fail, symptoms include a humming unit with no motor start, the compressor short-cycling, the fan running while the compressor does not (or vice versa), or the unit tripping on thermal overload due to motor strain.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e P291-0403 — 4 MFD | 370V | Oval case | Fan motor capacitor  |  P291-1503 — 15 MFD | 370V | Oval case | Compressor run capacitor | ±5% factory tolerance on both\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier\/Totaline capacitors are manufactured to exact factory tolerance specs.

Always verify MFD and voltage ratings against the data plate inside your unit's control compartment before ordering. Note that P291-0403 has been superseded by P291-0404 and P291-1503 by P291-1504 in some production runs — our team can verify the correct fit for your serial number. Questions?
