Single run capacitors maintain a steady electrical charge to keep PSC blower motors running at peak efficiency. When either capacitor weakens or fails, you'll typically notice sluggish blower startup, reduced airflow, a humming motor that won't spin up to speed, or a tripped thermal overload that shuts the motor down entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e P291-0403 — 4 MFD (microfarad) | 370 VAC | Oval case | 50\/60 Hz; P291-1503 — 15 MFD (microfarad) | 370 VAC | Oval case | 50\/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e These are genuine Carrier\/Totaline OEM capacitors built to exact factory MFD tolerance (±5%).
