Originally supplied under part number \u003cstrong\u003eP291-0753\u003c\/strong\u003e (now superseded by P291-0754), this oval-style 7.5 MFD 370V capacitor is responsible for sustaining the blower motor's continuous operation once it has started. When it degrades or fails, symptoms include a blower motor that hums but won't spin, sluggish airflow, intermittent shutdowns, or a tripped thermal overload on the motor — all signs the capacitor can no longer hold its charge.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 7.5 MFD (microfarad) | 370V rated (440V-rated successor P291-0754 is a direct upgrade) | Oval form factor | OEM-matched ±5% tolerance for precise motor performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM Carrier capacitor is manufactured to exact factory tolerances.
