The run capacitor provides the continuous phase-shifted current that keeps the blower motor spinning at proper speed and efficiency. When this capacitor weakens or fails, you'll typically notice the blower motor humming but not starting, stalling mid-cycle, or running sluggishly — all of which reduce airflow and can cause the heat exchanger to overheat and trip the high-limit switch.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 10 MFD (microfarad) | 370V rated | Oval case | ±6% tolerance | 50\/60 Hz | 10,000 AFC protected | Non-PCB dielectric fluid | UL approved\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This Totaline\/Carrier OEM capacitor meets exact factory tolerance specifications.
