What it is

This is the mains voltage wiring harness used on Ideal Logic+ Combi boilers. It carries mains supply and control connections between the boiler's electrical components, forming part of the appliance's internal wiring loom. The harness is supplied as a single assembly by Ideal and is listed under the cables, leads and wiring harnesses spare part group.

Signs this part needs replacing

  • The boiler fails to power up or the display stays blank with the supply confirmed at the isolator
  • Intermittent faults that come and go when the wiring loom is moved or the casing is disturbed
  • Visible scorching, discoloured insulation or brittle, cracked conductors on the harness
  • Loose, corroded or heat-damaged spade terminals and plugs that no longer grip
  • Repeated fuse blowing or tripping traced to the mains voltage wiring rather than the PCB
