What it is

The Ferroli 39838960 flame sensing electrode lead is a lead assembly for the flame sensing electrode circuit on Ferroli gas boilers. It carries the flame signal from the sensing electrode back to the boiler control board, so the board can confirm a flame has been established and shut the gas valve if it has not. It is listed for the Fertech 25 OV and Optimax HE Plus 25 OV open vent models.

Signs this part needs replacing

  • Boiler locks out or fails to detect flame after the burner has lit
  • Repeated ignition attempts, with the burner lighting and then cutting out
  • Intermittent flame failure faults or lockout codes
  • Cracked, brittle or heat-damaged insulation along the lead
  • Corroded, loose or discoloured terminals at the electrode or control board

Before you order

  • Confirm your appliance is a Ferroli Fertech 25 OV or Optimax HE Plus 25 OV
  • Check the GC number on the appliance data badge against the numbers listed above
  • Inspect the electrode and the lead routing to confirm the fault lies with the lead before ordering
