The flame sensor monitors the burner flame during operation, sending a microamp signal to the furnace control board to confirm ignition. If the signal is absent or falls below threshold, the control board shuts off the gas valve as a safety measure. This part is installed by licensed HVAC technicians as part of routine maintenance or when diagnosing ignition lockout faults on gas-fired heating equipment.\u003c\/p\u003e\n\u003cp\u003eThis flame sensor is designed for use in the GG XF Series gas-fired unit heaters. Unit heaters of this type are commonly found in commercial and industrial applications such as warehouses, garages, and manufacturing facilities where overhead or suspended gas heat is used. The j38r06890-003 is an OEM-replacement component suited for service work on these specific heater series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM-style replacement flame sensor for GG XF Series gas-fired unit heaters\u003c\/li\u003e\n  \u003cli\u003eMonitors burner flame to confirm ignition and enable safe gas valve operation\u003c\/li\u003e\n  \u003cli\u003eSends microamp rectification signal to the ignition control board\u003c\/li\u003e\n  \u003cli\u003eDirect replacement part minimizes diagnostic and installation time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct OEM-replacement flame sensor for GG XF Series gas-fired unit heaters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlame sensor replacement is performed by a licensed HVAC technician. Shut off all electrical power and close the manual gas shutoff valve before beginning service. Flame sensors are fragile ceramic and metal rod assemblies — handle with care and avoid touching the rod with bare hands, as skin oils can degrade performance. Follow all applicable local codes and the manufacturer service documentation when reinstalling the sensor and restoring the heater to operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Flame Sensor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: GG XF Series Gas Fired Unit Heaters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MESTEK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: j38r06890-003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MESTEK","offers":[{"title":"Default Title","offer_id":51233992474930,"sku":"J38R06890-003","price":118.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629414.jpg?v=1780114291","url":"https:\/\/voomisupply.com\/products\/mestek-j38r06890-003-flame-sensor-gg-xf-series","provider":"Voomi Supply","version":"1.0","type":"link"}
