What it is

The Ideal 134455 is a wiring harness supplied for Ideal Commercial Super Plus boilers and closely related commercial models in the same range. At 1540mm it carries the low-voltage control and power connections between the boiler's electrical components and the main control circuit. It is a serviceable electrical spare, so a damaged or chafed harness can be replaced without disturbing the rest of the wiring installation.

Signs this part needs replacing

  • Insulation that has cracked, hardened or chafed through along the run
  • Intermittent lockouts or faults that change when the harness is moved or flexed
  • Burned, discoloured or loose connector plugs and terminals
  • Exposed conductors, or a harness damaged during previous servicing
  • The boiler failing to fire, or individual components losing supply with no other obvious fault

Before you order

  • Check the GC number on the appliance data badge against the numbers listed for this harness.
  • Confirm the model name against the compatibility list, as this harness is specific to the Super Plus family.
  • Isolate the electrical supply at the fused spur before removing or refitting the harness.
  • Compare the routing and overall length with the harness being replaced, since 1540mm is particular to this variant.
