Product Details

Description

Ensure your heating system operates safely and efficiently with this high-quality Flame Sensor Rod. Designed as a critical safety component for gas furnaces and HVAC units, this sensor detects the presence of a flame once the burner ignites. If the sensor fails to detect a flame, it signals the control board to shut off the gas valve, preventing hazardous gas buildup. Common signs that your flame sensor needs replacement include the furnace starting and then immediately shutting down (short-cycling) or visible soot and oxidation on the rod. Constructed with a durable stainless steel probe and a high-temperature ceramic insulator, this replacement part provides reliable performance and helps extend the life of your heating equipment. Ideal for DIY furnace repair and professional HVAC maintenance to restore consistent heat during cold months.
