What it is
The Ideal 178936 is a SELV (safety extra-low voltage) master wiring harness manufactured by Ideal for its commercial boiler range. It carries low-voltage control and sensor signals between the boiler's control components, forming the master leg of the SELV loom. The harness is supplied as a complete assembly with its terminations, so it can be swapped as a single unit during fault finding or repair.
Signs this part needs replacing
- Intermittent lockouts or faults that clear when the loom is disturbed
- Control or sensor readings that drop out without a corresponding component fault
- Visible chafing, heat damage or brittleness on the harness insulation
- Corroded, loose or discoloured pins in the harness plugs
- Boiler failing to respond to the controls despite a healthy control board
Before you order
- Confirm the boiler model and serial number against the compatibility list, as harness routing differs between Imax XEL outputs
- Check whether the existing loom is the SELV master section or a different leg of the wiring before ordering
- Inspect the harness plugs and any seals at the entry points, and replace damaged gaskets or glands at the same time
- Work on the boiler internals should be carried out by a competent engineer
