Brahma Ignition and ionization electrode 12431457

Brahma ignition and ionization electrode 12431457 is a dedicated ignition electrode for gas burners, manufactured by Brahma. It is designed for use in Geffen MB 3.1 - 127 and 145 boilers. This electrode is used in the ignition sequence: when the burner control energizes the ignition transformer, a high-voltage spark jumps across the electrode tip to the burner earth, lighting the gas-air mixture. The part is supplied without fasteners.

Parts of this type are selected by matching the electrode tip shape and length, ceramic insulator diameter and length, and thread or mounting arrangement to the original. The cable and connection terminal must be compatible with the ignition transformer output. During installation, ensure the ceramic insulator is free from cracks, the electrode is securely fixed, and the spark gap is set according to the burner manufacturer's specification.

Items of this kind typically fail due to cracked ceramic insulators, worn or eroded electrode tips, or carbon buildup, which can cause ignition failure or intermittent operation. Symptoms include the burner failing to light, delayed ignition, or a flame that goes out shortly after lighting. Check the electrode for physical damage, correct gap, and secure mounting.
