Capacitors store and release the electrical charge needed to start and run the compressor and fan motors. A failing capacitor typically causes a loud hum with no motor movement, intermittent short-cycling, or a complete failure to start — replacing both as a set ensures all motor circuits are restored to factory spec and prevents a repeat service call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Dual Run Capacitor (P291-3553RS) — round case, 370V\/440V rated, factory-matched MFD tolerance ±3%; Start Capacitor (P281-1356) — high-inrush design for hard-start assist, matched to Carrier HA1BJX024000AAAA motor requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to exact Carrier factory tolerances.
