What it is

The GW3-A6 is a gas pressure switch manufactured by EOGB, supplied as a replacement for the GW3-A4. It is used on EOGB Dungs boiler applications, where it monitors gas pressure and signals the appliance controls accordingly.

Signs this part needs replacing

  • The boiler locks out or fails to fire on a call for heat.
  • Ignition is intermittent, with repeated lockout cycles.
  • The boiler cuts out or short-cycles during normal running.
  • A fault code relating to gas pressure or proving is displayed.

Before you order

  • Confirm the switch currently fitted is marked GW3-A4 or GW3-A6.
  • Check the appliance make and model against the fitment information before ordering.
  • Gas-carrying components must be fitted and commissioned by a Gas Safe registered engineer.
