What it is
The LGW3-A4 is a pressure switch supplied under the EOGB brand for EOGB Dungs boiler applications. It monitors pressure within the appliance's gas or air circuit and signals the control system when the set condition is met. The switch is a serviceable component within the boiler's safety and control chain.
Signs this part needs replacing
- The boiler fails to fire or locks out because the pressure signal is not being made.
- Intermittent lockouts that clear on reset but return during normal operation.
- The appliance runs erratically or shuts down part-way through a demand.
- Visible damage, contamination or moisture at the switch body or its connections.
- Fault codes or diagnostic indications pointing to a pressure switch fault.
Before you order
- Confirm the part number LGW3-A4 matches the switch fitted to the appliance.
- Check the appliance model against the EOGB Dungs fitment before ordering.
- Inspect the existing switch, its tubing and electrical connections for faults that may not originate at the switch itself.
- Verify that any fault indication relates to the pressure switch rather than another component in the safety chain.
