What it is

This is the Potterton 24V wiring harness, identified by the connector designations X22 - X23, part number 5142451. It is a wiring loom used on Potterton Commercial Sirius 2 and Sirius 3 boiler models. Its function is to carry low voltage control and signal connections between the X22 and X23 termination points within the appliance.

Signs this part needs replacing

  • Intermittent or complete loss of control signals between the X22 and X23 connections
  • Fault codes or lockouts traced to harness continuity during electrical testing
  • Visible damage to the loom, such as chafed, cracked or heat-affected insulation
  • Loose, corroded or heat-damaged terminals at either connector end
  • Boiler failing to respond to control inputs after the associated boards and sensors have been ruled out

Before you order

  • Confirm the part number 5142451 matches the harness currently fitted
  • Check that the existing harness connectors are marked X22 and X23
  • Verify the appliance model against the Sirius 2 or Sirius 3 FS90 / FS110 listings above
  • Inspect the connectors at both ends for damage that may also require attention
