What it is

The Baxi 7868434 is a fuse supplied as a service component for Baxi domestic gas boilers. It forms part of the appliance's electrical protection circuit, interrupting the supply if current exceeds the circuit's design limit. It is listed by the manufacturer under miscellaneous components rather than a specific assembly group.

Signs this part needs replacing

  • The boiler is completely dead with no display, no pump run and no fan start.
  • The appliance loses power immediately after the supply is switched on.
  • A fuse in the boiler's control circuit is visibly blown, blackened or has a broken element.
  • The boiler repeatedly trips the same protective fuse after reset.
  • No voltage is present at the control board despite a live supply at the isolator.

Before you order

  • Confirm your boiler's model and GC number against the fitment list above.
  • Check the fuse rating and type specified in the appliance's installation and service documentation before fitting.
  • Isolate the electrical supply and prove dead before opening the boiler casing.
  • If a replacement fuse fails again, investigate the underlying electrical fault rather than refitting.
