What it is

The Ideal 174475 is a wiring harness assembly for the Ideal Mini C32 and Mini HE boiler range. It bundles the flow switch, temperature probe and modulator connections into a single loom, carrying electrical signals and power between the boiler's control board and those components. This version is specified for boiler serial numbers N091410706 and later.

Signs this part needs replacing

  • The boiler fails to fire or locks out because the flow switch signal is not reaching the control board
  • Temperature readings become erratic, or the boiler cycles in a way that does not match demand
  • Modulation faults or unstable burner output traced to a broken modulator connection
  • Intermittent faults that appear or clear when the loom is moved or flexed
  • Visible damage to the cable: chafed, brittle or heat-affected insulation, or loose and corroded terminals

Before you order

  • Confirm the boiler serial number is N091410706 or later, as this harness is specified from that serial onwards
  • Check the GC number of your appliance against the compatibility list before ordering
  • Cross-reference the alternative part number 1780298 if you are matching against an older listing
