Ionisationselektrode De Dietrich 721986300

An ionisation electrode is a critical safety and control component in gas burners, responsible for detecting the presence of a flame. It works by sensing the ionisation current in the flame and sending a signal to the control board to keep the gas valve open. If the electrode is dirty, damaged, or worn, the burner may fail to ignite or shut down unexpectedly. Replacing an ionisation electrode is a common repair task during boiler maintenance, ensuring reliable and safe operation of your heating system.
