ACV-202004-Ionisationskabel

This is an ACV 202004 ionisation cable, also listed under manufacturer codes 202004 and 129.616.008. It belongs to the category of ignition cables and connectors. An ionisation cable connects the ionisation electrode to the burner control, carrying the microamp flame-proving signal that confirms combustion. Such cables are silicone-insulated to withstand the high temperature near the burner and the voltage spikes from the ignition spark. A hardened, cracked, or moisture-damaged insulation will leak the signal to earth, causing the burner control to register a false flame or a no-flame condition and lock out. When selecting a replacement ionisation cable, confirm the length and the connector type at both ends. The cable end that plugs into the ionisation electrode and the terminal that connects to the control box must match the existing components. Inspect the old cable for brittleness, cracks, or burn marks before fitting the new one. Even if the cable appears intact, a slight leakage can imitate a faulty electrode or control board, so replacement of a suspect cable is a straightforward first step in troubleshooting intermittent lockouts.
