The run capacitor stores and releases the electrical charge that keeps the blower motor running at proper speed and efficiency. When this component fails, the furnace blower motor may hum without spinning, run sluggishly, overheat, or the furnace may fail to deliver conditioned air entirely — even if the burner fires normally. OEM part number \u003cstrong\u003eP291-0753\u003c\/strong\u003e has been superseded by the updated \u003cstrong\u003eP291-0754\u003c\/strong\u003e, which carries an upgraded 440V rating (fully backward-compatible with the original 370V application).\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 7.5 MFD (microfarad) | 440V rated (replaces original 370V P291-0753) | Oval case form factor | ±6% capacitance tolerance | UL approved | RoHS compliant | Rated for 60,000 service hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM Carrier capacitor is manufactured to exact factory tolerances, ensuring proper motor starting torque and sustained run performance. Generic off-brand capacitors often exceed ±10% MFD tolerance, causing blower motor stress, premature wear, and shortened furnace system life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Discharge the capacitor before touching terminals (use an insulated resistor or discharge tool).
