What it is
The Ideal 177931 is a SELV ERP base combi wiring harness — a pre-formed loom that carries separated extra-low-voltage control signals between the boiler's main PCB and the components mounted on the base of the appliance. It is supplied by Ideal for its combi boiler ranges and forms part of the internal electrical system that sequences ignition, fan and pump operation. Fitting a replacement harness restores those connections when the original loom or its plugs have been damaged.
Signs this part needs replacing
- Boiler locks out or logs intermittent fault codes with no obvious component failure
- Fan, pump or gas valve does not run when the PCB calls for it
- Visible scorching, brittleness or corrosion on the loom or its plugs
- Loose or intermittent contact at the base connectors
- Faults that appear or clear when the wiring is disturbed
Before you order
- Check the GC number on the appliance data badge against the compatibility list before ordering.
- Confirm the model name and GC number match one of the 21 listed appliances.
- Note the alternative part number 1777734 when cross-referencing older stock or documentation.
- Electrical work inside the boiler should be carried out by a competent person with the appliance safely isolated.
