The run capacitor maintains the continuous phase-shifted current supply that keeps the blower motor spinning at rated RPM throughout the heating cycle. When this capacitor weakens or fails, you'll notice the blower motor humming without starting, running sluggishly at reduced airflow, or stalling mid-cycle — all signs that heat is not being properly distributed through your home.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 10 MFD (microfarad) | 370V rated (370–440V compatible) | Oval case | ±6% tolerance | 10,000 AFC protected | Non-PCB | Operating range: -40°C to +70°C | 50\/60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier\/Totaline OEM capacitor manufactured to factory-exact tolerance.
