What it is

A temporized (time-delay) fuse rated at 250V 1.25A, manufactured under the Ariston brand and supplied as part number 61003635. It is a circuit protection component used on the control side of Ariston and Chaffoteaux gas boiler ranges. The temporized characteristic allows the fuse to ride out brief inrush currents without nuisance blowing, while still breaking the circuit on a sustained fault.

Signs this part needs replacing

  • The boiler is completely dead with no display or indicator lights.
  • Power is present at the supply but the appliance does not respond.
  • The fuse shows a visibly blown element or darkened glass body.
  • Continuity testing across the fuse reads open circuit.
  • A replacement fuse blows again shortly after fitting, indicating a fault elsewhere in the circuit.

Before you order

  • Confirm the existing fuse is rated 250V 1.25A and is of the temporized type.
  • Check your boiler model against the fitment list above before ordering.
  • Isolate the electrical supply before removing or fitting the fuse.
  • If a fuse has blown, investigate the underlying cause rather than replacing it repeatedly.
