What it is

The Worcester Bosch fusing element T0.5A is a 0.5 amp protection fuse used on the control circuit of Worcester and British Gas badged gas appliances. It interrupts the electrical supply when current rises above its rated value, shielding the printed circuit board and associated wiring from damage. The fuse is supplied as a pack of ten, which suits engineers holding stock for routine fault finding and repair work.

Signs this part needs replacing

  • The appliance is completely dead, with no display, LEDs or response to a call for heat
  • No ignition sequence or fan start when the boiler is switched on
  • The boiler locks out and will not reset, or resets and immediately trips again
  • A replacement fuse blows straight away, indicating a fault elsewhere on the circuit that needs tracing first
  • Intermittent shutdowns or erratic control behaviour on an otherwise healthy appliance

Before you order

  • Check the GC number and the appliance data badge to confirm the correct fuse rating for your model before fitting.
  • Cross-check the alternative and previous part numbers 1011013 and DD97903183 against the component being removed.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
