{"product_id":"oem-lennox-start-capacitor-with-relay-63w23","title":"OEM Lennox Start Capacitor with Relay — 63W23","description":"\u003cp\u003eThe Lennox \u003cstrong\u003e63W23\u003c\/strong\u003e is a genuine OEM start capacitor with an integrated potential relay, designed to give single-phase compressors the added torque they need to start reliably. On startup the capacitor and relay work together to boost the compressor motor, and the relay then removes the start capacitor from the circuit once the motor is up to speed. It is a direct factory component for the Lennox units that call for it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failing start capacitor or relay typically shows up as a compressor that hums but won't start, frequent breaker trips, hard or delayed starting, and short-cycling on the compressor overload. A capacitor that is bulged, leaking, or reading out of spec should be replaced immediately to avoid stressing the compressor windings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox specifies the exact capacitance and relay characteristics for each compressor. The genuine \u003cstrong\u003e63W23\u003c\/strong\u003e is built to those values, so the relay drops the start capacitor at the correct point and the compressor starts cleanly every cycle. Generic replacements may carry the wrong rating and cause weak starts or early failure. Choose the authorized \u003cstrong\u003e63W23\u003c\/strong\u003e for a proper fit and full rated performance in your Lennox system.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081123905907,"sku":"LNX-63W23","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-63W23.jpg?v=1783763740","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-start-capacitor-with-relay-63w23","provider":"National HVAC Parts","version":"1.0","type":"link"}
