Engineered specifically for high-efficiency furnace configurations, this replacement part, identified as \u003cstrong\u003eMPN 100074673\u003c\/strong\u003e, restores the communication loop between the burner and the ignition control module to prevent short-cycling.\u003c\/p\u003e\u003cp\u003eThis component operates by utilizing the principle of flame rectification, where the rod produces a small electrical current when submerged in the ionized air of the burner flame. The system controller detects this current to confirm that the pilot or main burner is lit; if the rod fails to sense the flame, the gas valve closes immediately to eliminate the risk of unburned fuel accumulation.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlame Rectification Accuracy:\u003c\/strong\u003e Ensures stable micro-amp signaling for precise combustion control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Temperature Durability:\u003c\/strong\u003e Crafted from heat-resistant alloys to withstand continuous thermal stress within the combustion chamber.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless Integration:\u003c\/strong\u003e Designed for exact fitment within Lochinvar equipment to ensure manufacturer-specified safety standards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Specifically designed for professional maintenance and repair of Lochinvar high-efficiency gas-fired HVAC furnace systems.\u003c\/p\u003e","brand":"LOCHINVAR","offers":[{"title":"Default Title","offer_id":43137730084958,"sku":"100074673","price":37.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/181472759.png?v=1786199457","url":"https:\/\/nationalboilersupply.com\/products\/lochinvar-100074673-flame-rod-hvac-furnace-parts","provider":"National Boiler Supply","version":"1.0","type":"link"}
