The start capacitor supplies a torque boost at the moment of start-up, and the potential relay switches it out of the circuit once the motor is running — ensuring reliable starts without stressing the components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e a compressor that hums but fails to spin up, tripped breakers on start-up, hard starts or rapid clicking, a chattering or silent relay, and a start capacitor showing bulging, leakage, or a blown top. A degraded start assembly commonly causes an outdoor unit to stop cooling during peak summer temperatures.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the Lennox \u003cstrong\u003e66K92\u003c\/strong\u003e is built to the precise capacitance, voltage, and relay switching values engineered for your equipment. Generic replacements with mismatched specifications risk insufficient starting torque, nuisance trips, and premature compressor wear. Choosing the OEM assembly restores factory-rated starting performance and helps protect the most expensive component in your system.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081124004211,"sku":"LNX-66K92","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-66K92.jpg?v=1783763737","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-start-assembly-kit-relay-start-cap-66k92","provider":"National HVAC Parts","version":"1.0","type":"link"}
