Unlike a dual run capacitor, a single run capacitor is dedicated to one motor — either the compressor or the condenser fan motor — providing the precise electrical charge needed to start and sustain operation. When this capacitor fails, you'll notice symptoms such as a humming sound with no motor engagement, intermittent shutdowns, or a compressor that struggles to start and trips the breaker shortly after. Replacing it promptly protects the motor windings from sustained start-current damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Replaces OEM part numbers P291-1003 and P291-1503 | Verify MFD rating and voltage (370V or 440V) on your unit's data plate before ordering | Factory-matched tolerance for reliable motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to exact factory MFD tolerances (±3%), ensuring proper motor starting torque and longevity.
