Ensure the safety and reliability of your heating system with this high-performance furnace flame sensor rod. Designed to provide accurate flame detection for gas-fired furnaces, this component is essential for preventing unburned gas from accumulating in your HVAC unit. When the burner ignites, the sensor detects the flame's presence and sends a continuous signal to the furnace control board to keep the gas valve open. A faulty, cracked, or oxidized sensor is a leading cause of furnace short-cycling—where the heater starts and then immediately shuts down. This replacement part features durable, high-temperature resistant construction and a ceramic insulator to ensure long-lasting performance and consistent ignition throughout the heating season.
