What it is

The Ferroli 39809420 transformer is a replacement transformer for Ferroli gas boilers. It is listed in the gas boiler spares range and is supplied for use in the Ferroli boilers shown in the fit list below.

Signs this part needs replacing

  • The boiler shows no display or control panel lights.
  • The boiler fails to start or ignite, with no fault code shown.
  • The boiler shuts down intermittently and does not reset normally.
  • The control board receives no low-voltage supply, which can be confirmed with a multimeter by a qualified engineer.
  • There is a burning smell or visible scorching around the transformer.

Before you order

  • Check the boiler make and model on the data plate against the fit list above.
  • Confirm the old transformer's part number or markings match 39809420 before ordering.
  • Isolate the boiler from the electrical supply before inspecting or replacing any internal component.
  • If you are not a qualified heating engineer, have the replacement fitted by one, as gas appliance work is subject to UK regulations.
