The flame sensor — also called a flame rod — is a safety-critical component that detects the presence of a burner flame during each ignition cycle. When it fails or becomes coated with oxidation, the control board cannot confirm ignition and will shut off the gas valve within 5–8 seconds of startup, triggering a safety lockout. The result: a furnace that briefly lights, then goes cold — often misdiagnosed as a gas valve or igniter failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Total length 4 5\/8\" | Distance to bend 3\" | Distance to end 1 5\/8\" | 120V gas furnace application | Country of origin: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the exact factory-specified OEM part.
