The dual run capacitor continuously powers both the compressor and condenser fan motor, while the start capacitor provides the high-torque burst of energy needed to get the compressor spinning under load. When either fails, symptoms include a loud hum with no motor movement, repeated tripped breakers, compressor short-cycling, or a fan that spins freely by hand but won't self-start under power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e P291-4074RS Dual Run Capacitor — matches factory MFD and 370V\/440V rating for HC1CJX048000AAAA | P281-8806 Start Capacitor — factory-rated MFD boost range and voltage | Round-case design | ±3% OEM tolerance on both units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to exact factory tolerances, protecting your compressor and fan motor from voltage spikes and premature wear. Generic aftermarket units commonly ship at ±10% MFD tolerance, which shortens compressor life and can void equipment warranties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always shut off power at the disconnect and discharge the capacitor terminals with an insulated resistor before handling. Tools needed: 1\/4\" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal. The start capacitor installs in series with the start winding; the dual run mounts in the unit's control compartment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e Both capacitors carry a 1-year OEM factory warranty against defects.
