What it is

The Potterton 986328 ignition and ionisation unit is an electrode assembly used in Potterton Commercial gas boilers. It provides the spark that lights the burner and, once a flame is established, returns the ionisation signal to the control board to prove combustion. It sits within the Potterton Commercial electrodes range of gas boiler spares.

Signs this part needs replacing

  • Boiler attempts to ignite but no spark is present at the burner
  • Repeated ignition failure or lockout at the control panel
  • Burner lights briefly, then the boiler shuts down as flame is not proved
  • Visible cracking, contamination or heavy carbon build-up on the electrode
  • Intermittent starting as the electrode or its insulation degrades

Before you order

  • Confirm the appliance model and kW rating against the fit list
  • Check the part number on the existing electrode matches 986328
  • Inspect the electrode lead and its connections before replacing the unit
  • Isolate the boiler electrically and follow the manufacturer's safe isolation procedure before fitting
