Unlike dual run capacitors that support both the compressor and fan motor simultaneously, a single run capacitor is dedicated to one motor — in this case, the blower motor in your fan coil. When it fails, you'll notice symptoms such as a humming sound with no motor movement, intermittent blower operation, or a complete failure to start. Left unaddressed, a failing capacitor can overheat and damage the motor it supports, turning a low-cost repair into a costly replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory OEM-matched MFD and voltage rating | Round or oval case (per original) | ±5% tolerance to protect motor windings and extend equipment life\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors like the P291-1003 are manufactured to exact Carrier factory tolerances.
