What it is

The Potterton 5105945 is a fan and gasket assembly supplied for use in Potterton Suprima 30 L and Suprima 40 L gas boilers. The fan draws combustion air through the appliance and pushes flue products out to atmosphere, while the gasket seals the fan mounting face against the boiler casing. It is a serviceable component within the combustion circuit and is replaced as a complete assembly.

Signs this part needs replacing

  • The fan is noisy in operation, with rumbling, scraping or whining from the bearing
  • The boiler fails to fire or locks out at the start of a demand because the fan does not run
  • Intermittent lockouts or flue-related fault indications during or after ignition
  • The boiler overheats or the overheat thermostat trips repeatedly
  • Visible damage, distortion or sooting around the fan body or its mounting gasket

Before you order

  • Confirm the appliance is a Potterton Suprima 30 L or Suprima 40 L
  • Check the GC number on the appliance data badge against the model listing
  • Compare the part number on the existing fan assembly with 5105945
  • Check the condition of the fan mounting face and flue connections before fitting
