What it is

The Sime air pressure switch, part number 6225711, is a replacement sensing component used on Sime Format and Planet Dewy appliances. It monitors pressure in the combustion air path and signals the control board once the fan has established the required airflow, allowing the appliance to move on to ignition. The switch is not classified as a gas part.

Signs this part needs replacing

  • The appliance locks out shortly after the fan starts, with no flame established
  • The fan runs but the sequence does not advance to ignition
  • Repeated or intermittent lockouts during a demand for heat
  • A fault code relating to air pressure or fan proving appears on the display
  • The appliance fires only occasionally, or drops out mid-cycle

Before you order

  • Match the GC number and appliance model against the compatibility list; the same switch is listed against several Sime model numbers.
  • Compare the number on the existing switch body with 6225711 and the alternative number 2040920 before ordering.
