Product Details

Description

Ensure your heating system operates safely and efficiently with this premium flame sensor rod. Designed specifically for gas furnaces and HVAC units, this critical safety component monitors the burner's flame to ensure the gas valve only remains open when a fire is present. If your furnace starts but shuts off after a few seconds, a dirty or failing flame sensor is a common cause. Replacing a worn sensor prevents unnecessary system shutdowns and improves reliability during peak heating season. Constructed with high-grade, heat-resistant materials, this rod is built to withstand the intense environment of the burner assembly, providing accurate flame rectification for your home's comfort and safety.
