The run capacitor stores and releases an electrical charge that keeps the blower motor spinning at the correct speed and torque throughout the heating cycle. When this component fails, you'll typically notice the blower motor humming without starting, the furnace short-cycling, or in some cases a complete loss of airflow — leaving the heat exchanger to overheat and trigger a high-limit lockout. OEM part number P291-0753 has been superseded by P291-0754, the current factory-authorized replacement at the same 7.5 MFD \/ 370V specification.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 7.5 MFD (microfarad) ±6% | 370V rated (440V successor upgrade) | Oval case | UL approved | RoHS compliant | 60,000 service hour rated construction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier-authorized capacitor manufactured to factory tolerance. Generic aftermarket capacitors commonly run outside ±6% MFD tolerance, which accelerates bearing wear and shortens blower motor life — leading to a repeat repair bill.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor before handling by shorting the terminals with an insulated screwdriver.
