A single run capacitor maintains the steady electrical charge required to keep either the compressor \u003cem\u003eor\u003c\/em\u003e the condenser fan motor spinning during normal operation. Unlike a dual run capacitor, a single run unit is dedicated to one motor — making an exact MFD and voltage match absolutely critical for reliable, long-term performance. Common failure symptoms include the motor humming but failing to start, the system tripping on high-pressure lockout, or a burning smell coming from the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e P291-1503 | Single Run Capacitor | Factory-specified replacement for Carrier model PF1MNC036008AAAA | ±5% MFD tolerance or tighter as factory-rated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This is a genuine Carrier OEM capacitor — factory-tested to exact tolerances.
