What it is

The Fan/Terminal Block M3 Cable, part number 5141507, is a Potterton Commercial wiring assembly that connects the fan to the terminal block within the appliance. It is used on Potterton Commercial Sirius 2 and Sirius 3 gas boilers, carrying the supply and control connections the fan needs to run.

Signs this part needs replacing

  • The fan fails to run, with no supply reaching it from the terminal block.
  • The fan runs intermittently as the cable or its terminations make and break contact.
  • Visible heat damage, scorching or brittle insulation at the cable ends.
  • Loose, corroded or discoloured terminals where the cable meets the block.

Before you order

  • Confirm the boiler model and variant against the Sirius 2 and Sirius 3 fit list above.
  • Check the existing cable and terminal block for damage before ordering, so any other affected components are identified at the same time.
  • Verify the part number 5141507 on the existing cable or appliance documentation where possible.
  • Isolate the appliance from the electrical supply and follow the manufacturer's instructions before fitting.
