The run capacitor sustains the phase-shifted voltage required to keep the condenser fan motor spinning efficiently throughout every cooling cycle. When it weakens or fails, the motor loses torque — symptoms include a loud hum with no fan rotation, intermittent shutdowns on hot days, or the unit tripping the high-pressure limit. Left unaddressed, a failed run capacitor forces the motor to draw locked-rotor amperage, rapidly burning out the motor windings.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% factory tolerance | 50\/60 Hz | Replaces P\/N 97F5704, HC90AA004, HC91CA004, HC90AB004.

Generic aftermarket capacitors are typically rated at a looser ±10% MFD tolerance, which accelerates motor wear and reduces compressor longevity over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Locate and switch off the unit's disconnect and wait a minimum of 5 minutes for the capacitor to discharge fully before touching any terminals. Tools needed: 1\/4\" nut driver, needle-nose pliers, and a multimeter capable of reading capacitance. Photograph all wiring connections before removing the old capacitor. Match MFD and voltage ratings exactly to the data plate on your unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects in materials and workmanship.
