Weishaupt Electrode We2321001420-7

Weishaupt Electrode We2321001420-7 is an ionization and ignition electrode for Weishaupt burners WG5-WG40 and G1-G5 LN. It has an electrode length of 105.3 mm and is resistant to soot. This electrode is used in the flame zone to either ignite the fuel-air mixture or to prove flame presence by conducting a small rectified current. It is a consumable part that must be replaced periodically.

When selecting a replacement electrode of this type, key parameters to match include overall length, bend angle, diameter of the ceramic insulator, spark gap, and shape of the mounting flange. The electrode must fit the specific burner series, so physical dimensions and mounting pattern must match the existing assembly. Always verify dimensions and gap before fitting a replacement.

Common failure modes include erosion of the electrode tip, cracked ceramic insulator, soot deposits that bridge the gap, and gradual drift in the gap that delays or prevents ignition. When the electrode fails, the burner may fail to ignite or lock out due to no flame signal. Check the electrode for these issues if ignition problems occur.
