What it is

This is the PCB/spark detection cable, part number 5141506, manufactured by Potterton. It forms the electrical link between the boiler printed circuit board and the ignition and flame detection circuit on Potterton Commercial Sirius 2 and Sirius 3 appliances. It carries the ignition spark and the flame sensing signal between the board and the burner assembly.

Signs this part needs replacing

  • No spark at the ignition electrode despite the board calling for ignition
  • Repeated ignition lockouts or failed ignition attempts on start-up
  • Intermittent flame detection faults causing the burner to drop out
  • Visible damage to the cable insulation, such as chafing, cracking or heat marking
  • Burnt, corroded or loose terminals at the PCB or electrode end

Before you order

  • Confirm the boiler model from the data badge against the Sirius 2 or Sirius 3 fit list above
  • Check the existing cable and both connection points for damage before ordering
  • Verify the part number 5141506 matches the number on the cable or the manufacturer's parts listing
  • Inspect the PCB and electrode terminals for signs of arcing that may also need attention
