What it is

The Ideal 134458 is a 1000mm wiring harness supplied for Ideal Commercial Super Plus appliances. It carries low-voltage control and sensor connections between the boiler's main control board and the components mounted around the casing and heat exchanger assembly. The harness is a direct replacement item for the original lead fitted to these commercial units.

Signs this part needs replacing

  • The appliance loses power intermittently or fails to start, with the fault tracing back to the loom rather than the board
  • Fault codes relating to sensor or communication circuits appear and clear when the harness is disturbed
  • Insulation is chafed, cracked, brittle or heat-damaged along the run
  • Connector terminals are loose, corroded, discoloured or pushed back out of the housing
  • Components cut in and out when the harness is flexed or moved by hand

Before you order

  • Confirm the appliance model and GC number against the compatibility list before ordering
  • Check the routing and connector layout of the existing harness against this 1000mm item
  • Cross-reference the alternative number 1176234 when working from older documentation or parts lists
