Heating Spare POWRMATIC 142423010 IGNITION ELECTRODE - 3480069

The Powrmatic 142423010 is an ignition electrode supplied by Powrmatic for use in its heating appliances. The electrode sits in the combustion area and provides the spark that lights the burner on a call for heat from the control system. It is a serviceable ignition component, so it is replaced when the spark path breaks down or the ceramic insulation is damaged.

• The burner fails to light and the appliance goes to lockout on start-up
• No visible spark at the electrode when the ignition sequence runs
• A weak, intermittent or misaligned spark that lights the burner only occasionally
• Cracking, crazing or sooting on the ceramic insulator or electrode tip
• Repeated lockouts that clear after a reset but return on the next demand

• Check the appliance model and serial plate, then compare the original electrode against this part number and the alternative number 3480069
• Inspect the electrode tip and gap position with the old part in hand, as the mounting and probe length must match the burner arrangement
• Check whether the ignition lead and its insulation are also degraded, since a poor lead can imitate an electrode fault
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
