The flame sensor monitors burner operation by detecting the presence of an ionization current when the burner flame is established. If no flame is detected, the control board shuts off the gas valve to prevent unburned fuel from accumulating. This part measures 4.75 inches in length and weighs 0.13 pounds, making it a compact, direct-replacement component. It is typically installed by a licensed HVAC technician during routine furnace service or as part of a no-heat diagnostic repair.\u003c\/p\u003e\u003cp\u003eThis flame sensor is suited for residential gas furnace applications where the original sensor has failed, corroded, or is causing nuisance lockouts. Flame sensor degradation is a common cause of intermittent heating faults, and replacement is a standard corrective action during a no-heat service call. The part fits into furnace burner assemblies where the sensor rod mounts in the path of the burner flame.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplacement flame sensor for gas furnace burner assemblies\u003c\/li\u003e\n\u003cli\u003eDetects ionization current to confirm active burner flame\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 4.75 inches length, 4.5 inches width, 2.5 inches height\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.13 pounds for easy handling during installation\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement for straightforward swap-out service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement flame sensor for residential gas furnace systems.

Shut off power to the furnace at the disconnect switch and turn off the gas supply before beginning any service work. The sensor rod must be positioned correctly in the path of the burner flame for accurate ionization detection. Refer to the furnace manufacturer service manual for mounting location and hardware specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OXBOX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: sen02528\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OXBOX","offers":[{"title":"Default Title","offer_id":51138950758706,"sku":"SEN02528","price":124.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533984.gif?v=1778266461","url":"https:\/\/voomisupply.com\/products\/oxbox-sen02528-flame-sensor","provider":"Voomi Supply","version":"1.0","type":"link"}
