The flame sensor — also called a flame rod — is a safety component mounted inside the burner assembly. Once the igniter lights the burner, the sensor passes a small electrical current through the flame to confirm combustion is active. When the sensor fails or becomes coated with oxidation, the control board cannot verify the flame and will shut down the gas valve within 5–8 seconds as a safety lockout. The furnace may attempt 2–3 ignition cycles before posting a fault code. This is one of the most common furnace no-heat calls, and in most cases, replacing this sensor restores full operation immediately.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e L-Bend style | Total length: 3½\" | Distance to bend: 1½\" | Bracket length: 1½\" | Push-in connector | Made in USA | OEM part number: 50HJ401431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory part, manufactured to exact dimensional and conductivity tolerances.
