What it is

The Ideal 138895 is a detection electrode manufactured by Ideal for use in Ideal Commercial Concord CXDI appliances. It sits in the combustion path and provides the flame signal that the control board uses to confirm the burner has lit and is burning safely. When the electrode or its lead degrades, the board loses that signal and shuts the appliance down.

Signs this part needs replacing

  • Burner lights but the appliance locks out shortly afterwards
  • Repeated lockouts on start-up with no sustained flame signal
  • Intermittent shutdowns during a demand for heat or hot water
  • Electrode tip visibly eroded, cracked, or coated in carbon deposits
  • Ceramic insulator showing cracks or tracking marks

Before you order

  • Check the appliance model and serial plate against the compatibility list to confirm the electrode suits your Concord CXDI unit
  • Note the alternative number 1176686 when cross-referencing older documentation
  • Inspect the electrode lead and ceramic insulator at the same time, as damage there produces the same fault symptoms
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
