The flame sensor is a critical safety component that detects the presence of a burner flame using an ionization\/rectification method — it passes a small electrical current through the flame and confirms combustion is active. When the sensor becomes coated with oxidation or fails entirely, the furnace control board cannot verify ignition, causing the system to shut off the gas valve within 5–8 seconds and enter a safety lockout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90° angled flame rod with integrated mounting bracket | Factory OEM tolerance | Compatible with standard 1\/4\" push-on wire terminal | Approximate rod length 1.6\" | Overall dimensions approx. 4.9\" × 1.75\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, ensuring exact rod geometry, insulator material, and mounting alignment.
