What it is

The Biasi BI1005105 is a delayed-action (time-lag) fuse rated at 1.6 A and 250 V. It is a circuit protection component used on the control side of Biasi gas boilers, where it guards the PCB and associated wiring against overcurrent faults. The delayed characteristic allows brief inrush currents to pass without nuisance blowing.

Signs this part needs replacing

  • The boiler is completely dead with no display, no fan and no ignition sequence
  • The fuse has blown and shows a broken element or blackened body
  • The fuse blows again immediately after being replaced, indicating a fault elsewhere in the circuit
  • Intermittent shutdowns or loss of control voltage on the boiler

Before you order

  • Confirm the rating on the existing fuse matches 1.6 A at 250 V and that it is a delayed-action type
  • Check the boiler model against the fitment list above before ordering
  • If a replacement fuse blows straight away, investigate the underlying electrical fault rather than fitting another fuse
  • Verify the fuse holder and clips are undamaged and making good contact
