What it is

The Ferroli 39804990 is the MF01 printed circuit board used in the control circuit of Domina 80E and Modena 80E boilers. It carries the boiler's operating logic, handling ignition sequencing, fan and pump control, temperature monitoring and lockout protection. The board is supplied as a complete unit for direct replacement of the original MF01 assembly.

Signs this part needs replacing

  • Boiler fails to fire or runs through the start sequence without igniting
  • Repeated lockouts or fault codes that clear only after a power reset
  • Fan, pump or diverter output not energised despite a call for heat
  • Intermittent operation, with the boiler cutting out at random
  • Visible scorching, tracking or swollen capacitors on the board

Before you order

  • Confirm the appliance GC number against the compatibility table above; the MF01 board is used across more than one Ferroli model reference.
  • Check the board currently fitted against the previous part numbers listed, as earlier revisions may be present in older appliances.
  • Inspect the wiring harness, plugs and earth connections before fitting, as damaged connectors can mimic board failure.
