What it is

The Ariston gas valve cable (part number 999988) is the wiring harness that links the gas valve to the boiler control PCB on Ariston Microsystem RFFI appliances. It carries the control signals that open and close the gas valve during ignition and modulation. This part is specified for appliances from serial number 2320030800001 onwards.

Signs this part needs replacing

  • Boiler fails to ignite or locks out with a gas valve fault
  • Gas valve does not open when the PCB calls for heat
  • Intermittent flame or repeated ignition attempts
  • Visible damage, scorching or fraying on the cable or its connectors
  • Loose or corroded plug at the gas valve or PCB end

Before you order

  • Confirm the boiler serial number is 2320030800001 or later
  • Check the model and edition against the fit list
  • Inspect the existing cable connectors to confirm they match
  • Check that the fault code or diagnostic sequence points to the gas valve circuit
