This single component stores and delivers the electrical charge that both starts and keeps running your compressor (the 50 MFD side) and outdoor condenser fan motor (the 5 MFD side). A healthy capacitor is essential for reliable, efficient operation of your Lennox air conditioner or heat pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e The compressor or fan hums but won't start, the outdoor fan spins slowly or not at all, the unit trips the breaker, cooling is weak, or you hear clicking as the system tries and fails to start. A bulging, leaking, or swollen top on the old capacitor is a sure sign it has failed. Capacitors are one of the most common HVAC failure points and often the culprit behind a no-cooling call.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The \u003cstrong\u003eY9644\u003c\/strong\u003e is built to Lennox's exact microfarad, voltage, and tolerance specifications, ensuring correct motor torque and full-rated efficiency.
