This critical safety component acts as the \"eyes\" of the furnace ignition system, detecting the presence of a flame once the burners ignite. If the sensor fails to verify a flame within seconds, it signals the control board to shut off the gas valve, preventing hazardous gas buildup and ensuring safe system operation.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eTechnical Performance:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eConstructed from high-grade, heat-resistant metal and high-density alumina ceramic insulation, this sensor is built to withstand the intense thermal cycling of a furnace burner. Being a \u003cstrong\u003eGenuine OEM\u003c\/strong\u003e part ensures the electrode is positioned at the exact height and angle required by the manufacturer. This precision prevents \"nuisance trips\" or ignition lockouts caused by incorrect microamp readings—a common issue with generic, non-OEM sensors that lack the specific metal conductivity required by Protech™ control boards.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Flame Detection:\u003c\/strong\u003e Sends a consistent microamp signal to the control board to verify burner ignition and maintain safe operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine OEM Reliability \u0026amp; Fitment:\u003c\/strong\u003e Guaranteed to align perfectly with the burner assembly in Rheem\/Ruud units without manual bending or modification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Integration:\u003c\/strong\u003e Immediately shuts down gas flow if a flame is not detected, protecting your home from unburned gas accumulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Temperature Durability:\u003c\/strong\u003e Features a heavy-duty ceramic insulator and high-nickel alloy rod to resist oxidation and carbon buildup.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 62-23543-01 (Replaces 62-23543-01)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Rheem \/ Ruud (PROTECH™ Genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Furnace Flame Sensor \/ Flame Probe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Length:\u003c\/strong\u003e 4.31 Inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Length:\u003c\/strong\u003e 3.31 Inches (Metal Probe)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e 1\/4\" Male Spade Terminal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Single-hole offset bracket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 0.15 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e🛠️ HVAC Depot Pro Tip: The Microamp Check\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eIf your furnace lights for 2-5 seconds and then shuts off, the flame sensor is likely dirty or failing.
