It briefly stores and releases energy at startup, then drops out of the circuit, giving compressors and fan motors the extra push required to spin up quickly and reliably.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e a motor or compressor that hums or clicks but won't start, hard or delayed starting, frequent breaker trips at start-up, a buzzing sound from the electrical compartment, or a capacitor that appears bulged, swollen, or leaking. Because capacitors degrade with heat and age, they are one of the most common HVAC failure points.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the Lennox 72H72 is specified to the exact microfarad (MFD) rating and voltage your motor requires.
