What it is

The Potterton 5117672 is a wiring harness that connects the fan and spark generator within the appliance. It is a manufacturer-supplied electrical loom for Potterton Promax boilers and Promax Store cylinders. The harness carries the low-voltage connections required for fan operation and ignition spark generation.

Signs this part needs replacing

  • The fan runs intermittently or not at all despite a healthy fan assembly
  • No ignition spark is produced when the appliance calls for heat
  • Insulation on the harness is cracked, brittle or heat-damaged
  • Connectors are loose, corroded or show signs of arcing or burning
  • Fault codes or lockouts point to fan or ignition circuit continuity

Before you order

  • Confirm the appliance model and serial number against the fitment list
  • Check the existing harness connectors and pin count match the part
  • Inspect the fan and spark generator before ordering, as the fault may lie with those components rather than the loom
  • Isolate the appliance from the electrical supply before any inspection or replacement
