Resideo Q354A1000/B Flame Sensor R-448A Enhanced Durability: Constructed from corrosion-resistantThe Resideo Q354A1000 B Flame Sensor is a precision engineered flame rectification sensor designed for rigorous HVAC environments. Featuring a 2. 92 inch Kanthal rod, this component is essential for detecting the presence of a main burner flame in heating systems. It provides a vital signal to the direct spark ignition (DSI) or hot surface ignition control board, ensuring that gas flow is only permitted when a stable flame is established. This sensor
