Ideal Ignition Electrode Kit 173528 replacement part

The Ideal ignition electrode kit 173528 produces the ignition spark needed to light the burner and support reliable start-up. If the electrode is worn, cracked, or carboned up, it can cause failed ignition, repeated lockouts, delayed firing, or intermittent heating and hot water. Replacing it with the correct kit is a reliable fix that restores consistent ignition and helps reduce nuisance shutdowns.
