On call for cooling, the capacitor and relay boost the motor off the line, and the relay then removes the start capacitor from the circuit once the compressor is up to speed — protecting both components from overheating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e a compressor that buzzes or hums without starting, breaker trips on start-up, hard or repeated clicking starts, an audibly chattering relay, or a start capacitor that is swollen, leaking, or has vented. These issues typically show up first during the hottest part of the day when the compressor is under the greatest load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the Lennox \u003cstrong\u003e63W24\u003c\/strong\u003e is calibrated to the microfarad, voltage, and relay pickup\/dropout ratings specified for the units it serves. Off-brand kits with the wrong values can leave the compressor short on torque, trigger nuisance trips, or accelerate wear. Installing the OEM assembly keeps starting performance within factory spec and helps safeguard the compressor.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081123971443,"sku":"LNX-63W24","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-63W24.jpg?v=1783763735","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-start-assembly-kit-relay-start-cap-63w24","provider":"National HVAC Parts","version":"1.0","type":"link"}
