What it is

The Ferroli flame sensing lead (part number 39804711) is a wiring lead that connects the flame sensing electrode to the boiler control board. It carries the ionisation signal used by the board to confirm that a flame is present. The lead is used across a number of Ferroli Domina and Modena gas boiler models.

Signs this part needs replacing

  • Boiler locks out or fails to detect flame after the burner has lit
  • Repeated ignition attempts followed by shutdown
  • Intermittent lockouts that clear after a reset
  • Cracked, brittle or heat-damaged insulation along the lead
  • Loose, corroded or discoloured terminal at the electrode or control board end

Before you order

  • Confirm your boiler model and GC number against the fit list above
  • Check the terminal type and lead routing at both ends match the existing part
  • Inspect the flame sensing electrode itself, as a worn electrode can produce the same symptoms as a faulty lead
