What it is
The Ideal 178937 is a SELV (Safety Extra Low Voltage) slave wiring harness used on Ideal Commercial appliances. It carries low-voltage control and signal connections between the slave module and the appliance's control circuit, so the two sections communicate correctly during firing, modulation and shutdown. It is a direct replacement loom for the original factory-fitted harness.
Signs this part needs replacing
- The slave module fails to respond, or the appliance will not run through its full sequence
- Intermittent lockouts or fault codes that clear and return without an obvious mechanical cause
- Visible damage to the loom: chafed insulation, scorched or brittle cable, exposed conductors
- Loose, corroded or heat-damaged pins in the plug connectors
- Continuity faults traced along the harness during electrical testing
Before you order
- Confirm the appliance model and serial number against the compatibility list, as the same harness may not suit every IMAX XEL variant
- Check the part number 178937 on the existing harness or in the appliance documentation before ordering
- Isolate the appliance from the electrical supply and follow the manufacturer's wiring diagram when fitting
- Any work on a gas appliance should be carried out by a competent, registered engineer
