What it is

This is an SELV (separated extra-low voltage) wiring harness manufactured by Ideal for use in its commercial heating appliances. It forms part of the low-voltage control circuit, carrying signals between the control board and the sensors and switches it monitors. The harness is supplied as a complete loom, ready to be routed and connected in place of the original.

Signs this part needs replacing

  • Insulation that is cracked, chafed or heat-damaged along the loom
  • Terminals that are loose, corroded or show signs of arcing
  • Intermittent faults, spurious lockouts or error codes traced to the low-voltage circuit
  • Continuity faults or open circuits found when testing the harness with a meter
  • Moisture ingress or rodent damage to the cable run

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering
  • Check the existing harness part number where it is legible, as Ideal has used more than one loom across the Imax XEL range
  • Isolate the electrical supply and allow the appliance to cool before removing the old harness
  • Work inside a commercial gas appliance should be carried out by a suitably qualified engineer
