What it is
The Riello 3007423 is an air pressure switch carrying the GS20D designation, manufactured by Riello for its oil burner range. It monitors the air supply side of the burner and signals the control box that combustion air is present before the burner is allowed to fire. It is listed within oil boiler spares for Riello burner assemblies.
Signs this part needs replacing
- Burner repeatedly locks out even though the fan runs and air flow appears normal
- Burner fires intermittently, with lockout occurring more often on start-up
- Control box indicates an air pressure or air proving fault
- Burner fails to reach flame establishment despite the fan motor running
- Lockouts clear on reset but return on the next demand for heat
Before you order
- Confirm the burner model and control box fitted to the appliance
- Check the part number and GS20D marking on the existing switch before ordering
- Inspect the sensing pipework and connections for blockage or leaks, as these can mimic a switch fault
- Verify that the fault is not caused by a dirty fan, restricted air intake or incorrect combustion settings
