When its coil energizes, the internal contacts close to route power where the control board commands, making it a key link between your thermostat signals and the components that actually move air in your Lennox system.\u003c\/p\u003e\u003cp\u003eWhen a relay fails you may see a blower or fan that won't start or won't shut off, intermittent operation, a buzzing or clicking sound from the control area, or contacts that are pitted and burned. Because a stuck or dead relay interrupts normal cycling, it often mimics a control-board or motor problem, so verifying the relay is a smart first step.\u003c\/p\u003e\u003cp\u003eInstalling the OEM \u003cstrong\u003e66463\u003c\/strong\u003e matters because it is built to the exact coil voltage and contact rating your Lennox equipment expects. A mismatched aftermarket relay can chatter, fail early, or fail to carry the load reliably. This factory-original part restores clean, dependable switching so your Lennox system cycles the way it was designed to.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081116664179,"sku":"LNX-66463","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-relay-fan-LNX-66463.jpg?v=1783763316","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-relay-66463","provider":"National HVAC Parts","version":"1.0","type":"link"}
