Yes, you must install the correct Suburban 525033 Igniter Electrode for NT Series furnaces to ensure your NT12SE operates safely and properly. The 525033 serves as both igniter and flame sensor, and using an incorrect or worn electrode often causes immediate shutdown of the new control module’s flame.
