What it is
The Ariston 65104672-01 is an air pressure switch rated at 74 Pa, used on Ariston CLAS FF gas boilers. It monitors the pressure difference created by the fan to prove that combustion air is moving through the appliance before the gas valve is allowed to open. It forms part of the boiler's safety interlock chain.
Signs this part needs replacing
- Boiler locks out or fails to fire, with a fan or air pressure fault indicated
- Fan runs but the boiler does not proceed to ignition
- Intermittent lockouts that clear on reset and return later
- Fault code relating to air pressure or flue pressure proving
- Visible damage, contamination or blocked sensing tubes at the switch
Before you order
- Confirm the boiler model and GC number against the appliance data badge
- Check the existing switch part number and pressure rating before removal
- Inspect the sensing tubes and fan for blockages or leaks, as these can mimic a failed switch
- Verify the electrical connections and wiring plug match the existing switch
