The flame sensor confirms that a flame is present after ignition by detecting the micro-amp current generated by the burner flame. If no flame is sensed, the control board shuts the gas valve to prevent unburned gas buildup, a critical safety function. Over time, the sensor rod develops a carbon or oxide coating that prevents proper detection, causing the furnace to ignite then shut down after a few seconds, a classic short-cycling symptom. This OEM replacement matches the original rod length, bracket, and terminal connection for a precise fit. Installation is easy and takes 10 to 15 minutes; remove one screw, disconnect the wire, and install the new sensor. Cut power first and avoid touching the rod with bare fingers. Genuine OEM construction guarantees accurate flame detection and dependable furnace cycling. Orders placed before 3PM CST ship same-day from our US warehouse.
