Ideal Wiring Harness Mains Voltage Slave 178903

The mains voltage slave wiring harness, Ideal part 178903, is a replacement wiring loom for Ideal Commercial appliances. It carries mains supply to the slave side of the unit, linking the incoming supply and control components to the slave assemblies within the casing.

Harnesses of this type sit in a hot, vibrating environment and are handled during every service visit, so the terminals, crimps and insulation are the usual points of failure rather than the cable itself.

• Intermittent or total loss of power to the slave side of the appliance
• Blown fuses or a breaker tripping when the appliance is powered up
• Visible heat damage, brittle or cracked insulation on the loom
• Discoloured, corroded or loose crimp terminals
• Continuity faults traced along the harness during fault finding

• Confirm the appliance model and serial number against the compatibility list before ordering, as Imax XEL variants use different looms.
• Compare the part number 178903 with the marking on the existing harness where it is still legible.
• Isolate the mains supply and prove dead before removing or refitting any mains voltage wiring.
• Mains voltage work should be carried out by a competent person.
