What it is

The Broag spark ignitor probe, part number 720405001, is an ignition electrode used on Broag Commercial gas boilers. It sits at the burner and provides the spark that lights the gas at start-up. It is listed within the Broag Commercial spare parts range.

Signs this part needs replacing

  • The boiler attempts to light but there is no spark at the burner
  • Repeated ignition attempts followed by a lockout or fault code
  • Intermittent ignition, with the boiler lighting on some attempts and not others
  • Visible damage to the electrode, such as a cracked ceramic insulator, eroded tip or heavy soot and carbon build-up
  • A weak or inconsistent spark when the electrode is observed during a call for heat

Before you order

  • Confirm the part number 720405001 matches the number on the existing electrode or in the manufacturer's parts list
  • Check the appliance model against the manufacturer's parts list to confirm compatibility
  • Inspect the electrode lead and its connection point, as a damaged lead can mimic an electrode fault
  • Isolate the electrical supply and gas before removing or fitting the electrode
