The flame rod detects the presence of a burner flame by conducting a small electrical current through the flame envelope, signaling the control board that ignition has been confirmed and allowing the gas valve to remain open. If the flame rod fails or becomes coated with oxidation, the furnace will lock out on a no-flame fault. This component is identified in service documentation as FL2 and is associated with the RUTGH95DV furnace platform. Licensed HVAC technicians typically service and replace this part during a furnace no-heat or intermittent-heat diagnostic.\u003c\/p\u003e\n\u003cp\u003eThis flame rod is suited for residential high-efficiency gas furnace applications where a flame-proving circuit is required for safe burner operation. It is associated with the RUUD RUTGH95DV furnace series. Replacement is common during seasonal maintenance calls, after nuisance lockouts caused by a contaminated or degraded sensor rod, or as part of a burner assembly service. Proper flame rod function is essential to the overall safety control sequence in induced-draft and condensing furnace designs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlame-proving sensor that confirms active burner flame to the furnace control board\u003c\/li\u003e\n  \u003cli\u003eIdentified as FL2 position in the RUTGH95DV furnace assembly\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement for restoring reliable ignition lockout protection\u003c\/li\u003e\n  \u003cli\u003eCompatible with the flame-sensing circuit architecture used in high-efficiency gas furnaces\u003c\/li\u003e\n  \u003cli\u003eDirect replacement minimizes diagnostic time during no-heat service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eAssociated with the RUUD RUTGH95DV furnace series based on available product documentation.

Shut off gas supply and disconnect electrical power to the furnace at the disconnect switch before beginning service. Handle the ceramic insulator carefully to avoid cracking, and do not apply grease or sealant to the rod or insulator. After installation, verify flame signal voltage or microamp reading at the control board to confirm proper sensor operation before returning the unit to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Position\u003c\/strong\u003e: FL2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Gas furnace flame-proving circuit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssociated Furnace Series\u003c\/strong\u003e: RUTGH95DV\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: RHEEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: rtg20223c\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RHEEM","offers":[{"title":"Default Title","offer_id":51233455341874,"sku":"RTG20223C","price":20.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629849.jpg?v=1780100435","url":"https:\/\/voomisupply.com\/products\/rheem-rtg20223c-flame-rod-sensor-gas-furnace","provider":"Voomi Supply","version":"1.0","type":"link"}
