This run capacitor supplies the continuous phase-shifted current a single-phase motor requires to generate consistent torque, keeping the fan turning at its designed speed so air flows properly across the coil for efficient heat transfer.\u003c\/p\u003e\u003cp\u003eA weak or failed \u003cstrong\u003e79W30\u003c\/strong\u003e capacitor typically causes a motor that hums but won't start, a fan that spins slowly or needs a manual push, intermittent no-cooling calls, or a unit that trips on high pressure due to reduced airflow. Physical warning signs include a bulged capacitor case, leaking oil, or a meter reading below the rated 7.5 MFD, all of which indicate the capacitor should be replaced before it damages the motor.\u003c\/p\u003e\u003cp\u003eChoosing the OEM \u003cstrong\u003e79W30\u003c\/strong\u003e guarantees the exact 7.5 MFD capacitance and 440V rating matched to your Lennox motor at the factory. Off-spec capacitors force the motor to run inefficiently and hot, accelerating winding failure. This factory replacement restores full motor performance, protects against premature wear, and preserves the reliability and warranty integrity of your Lennox equipment.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081124725107,"sku":"LNX-79W30","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-oval-single-LNX-79W30.jpg?v=1783763461","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-run-capacitor-7-5-mfd-440v-oval-79w30","provider":"National HVAC Parts","version":"1.0","type":"link"}
