What it is

The PUMP PREDISP/PWM FAN WIRING is a wiring assembly supplied by Potterton Commercial under part number 5141495. It forms the electrical link between the pump predisposition and the PWM-controlled fan circuit on Potterton Commercial Sirius 2 and Sirius 3 gas boilers. The part sits within the fan section of the commercial boiler spares range.

Signs this part needs replacing

  • The fan runs at a fixed speed or does not respond to a speed demand from the control
  • Intermittent or failed fan operation traced back to the wiring run
  • Chafed, brittle or heat-affected insulation on the harness
  • Loose, corroded or discoloured terminals at the harness plugs

Before you order

  • Confirm the boiler model against the Sirius 2 and Sirius 3 list above
  • Check the existing harness carries the part number 5141495
  • Establish that the fault lies with the wiring rather than the fan motor or control board
