What it is

The Biasi BI1665104 is a 400 mA time-delay (T-rated) fuse used in Biasi gas boilers. It protects the appliance's control circuitry, tolerating brief inrush currents while still breaking the circuit under sustained overload. It is fitted across the Garda and RIVA Advance HE ranges.

Signs this part needs replacing

  • The boiler has no power, display or response after the fuse has ruptured
  • The fuse element is visibly broken or the glass body is blackened
  • Continuity testing across the fuse reads open circuit
  • The boiler repeatedly fails to start or trips after a fuse change

Before you order

  • Confirm the rating and characteristic on the failed fuse match 400 mA and T.
  • Inspect the fuse holder and clips for corrosion, arcing or heat damage.
  • Isolate the boiler from the electrical supply before removing or fitting the fuse.
