Working together, these components deliver the extra torque a single-phase compressor needs to break away from a standstill, then drop the start capacitor out of the circuit once the motor reaches running speed. This kit is engineered to the exact electrical specifications of the Lennox condensing units and heat pumps it was built for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e a compressor that hums but won't start, frequent tripping of the breaker on start-up, hard or clicking starts, a buzzing or clicking relay, or a bulged\/leaking start capacitor. A weak or failed start assembly is one of the most frequent causes of an outdoor unit that stops cooling on hot days.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the Lennox \u003cstrong\u003e81J69\u003c\/strong\u003e is matched to the microfarad rating, voltage, and pickup\/dropout values your compressor was designed around. Generic substitutes with mismatched values can shorten compressor life, cause nuisance trips, or fail to provide enough starting torque. Choosing the OEM assembly protects your compressor investment and keeps the system running at rated performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081123938675,"sku":"LNX-81J69","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-start-LNX-81J69.jpg?v=1783763738","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-start-assembly-kit-relay-start-cap-81j69","provider":"National HVAC Parts","version":"1.0","type":"link"}
