It provides the electrical charge that both the compressor and condenser fan motor depend on to start and run, delivering the phase-shifted current these motors need for efficient, steady operation. The oval housing of the \u003cstrong\u003e12L70\u003c\/strong\u003e fits the compartment layout of the Lennox units it was designed for.\u003c\/p\u003e\u003ch3\u003eCommon Failure Symptoms\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCompressor or fan motor hums without starting\u003c\/li\u003e\n\u003cli\u003eFan turning slowly or the unit blowing warm air\u003c\/li\u003e\n\u003cli\u003eSystem short-cycling or tripping the circuit breaker\u003c\/li\u003e\n\u003cli\u003eBulged, leaking, or burnt-smelling capacitor\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause it cycles with every call for cooling, the capacitor faces constant electrical and heat stress and is a common failure point. Replacing the \u003cstrong\u003e12L70\u003c\/strong\u003e restores correct capacitance and protects the more expensive motor and compressor from overload.\u003c\/p\u003e\u003ch3\u003eWhy OEM Matters\u003c\/h3\u003e\u003cp\u003eGenuine Lennox capacitors are built to the precise MFD and voltage tolerances your system requires. The OEM \u003cstrong\u003e12L70\u003c\/strong\u003e ensures an exact fit, dependable long-term performance, and preserves your Lennox equipment warranty — assurances aftermarket capacitors rarely match.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081126887795,"sku":"LNX-12L70","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-oval-dual-LNX-12L70.jpg?v=1783760360","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-50-10-mfd-370v-oval-12l70","provider":"National HVAC Parts","version":"1.0","type":"link"}
