What it is

The Glow-worm 0020020763 is an igniter assembly used across a number of Glow-worm gas boiler ranges. It generates the high-voltage spark at the burner during the ignition sequence, lighting the gas when the appliance receives a call for heat or hot water. Once the flame is established and proved, the igniter stops sparking until the next demand cycle.

Signs this part needs replacing

  • The boiler attempts to fire but does not light, then locks out
  • No audible spark at the burner during the ignition sequence
  • Repeated ignition attempts before the appliance goes to lockout
  • Intermittent lighting, particularly in damp conditions or after long idle periods
  • A fault code or lockout pattern consistent with an ignition failure

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the correct fitment.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
  • Inspect the ignition lead and electrode condition at the same time, as a damaged lead can mimic igniter failure.
