What it is

The Ideal 178127 is an ionisation electrode supplied for Ideal Commercial appliances. It sits in the combustion area and provides the flame-sensing signal that the control board uses to confirm the burner has lit and is burning safely. It is listed under the Electrodes & Ignitions spare part group and carries the alternative number 9051208.

Signs this part needs replacing

  • The burner lights but the boiler locks out shortly afterwards, as the flame signal is not confirmed.
  • Repeated ignition attempts followed by a lockout on start-up.
  • Intermittent shutdowns during a demand for heat or hot water.
  • Visible damage, heavy contamination or a distorted probe tip on inspection of the electrode.
  • Unstable or erratic flame detection readings when the electrode is tested.

Before you order

  • Check the appliance model and, where shown, the GC number against the compatibility list before ordering.
  • Confirm the electrode position and lead connection match the burner arrangement on your appliance.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
