It powers the start and run cycles of both the compressor and condenser fan motor, supplying the phase-shifted current these single-phase motors need to run efficiently. The higher 440V rating gives the \u003cstrong\u003eY9642\u003c\/strong\u003e extra headroom and a longer service life under demanding conditions.\u003c\/p\u003e\u003ch3\u003eCommon Failure Symptoms\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOutdoor unit hums but the compressor or fan won't spin\u003c\/li\u003e\n\u003cli\u003eAir conditioner blows warm air while the fan runs\u003c\/li\u003e\n\u003cli\u003eFrequent hard starts or breaker trips\u003c\/li\u003e\n\u003cli\u003eSwollen, leaking, or discolored capacitor housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause the capacitor works every time the system cycles, it endures constant electrical and thermal stress and is a frequent point of failure.
