What it is
The Ideal low voltage wiring harness (177738) is a replacement loom that carries low voltage control signals around the boiler. It is manufactured by Ideal for the Logic+ Heat range and for Ideal Commercial appliances. The harness links the main control board to the low voltage sensors, switches and connectors the board monitors during a heating cycle.
Signs this part needs replacing
- The boiler locks out or throws intermittent fault codes with no obvious failed component
- The control board reports sensor or communication faults that clear and return
- Visible chafing, scorching or brittle insulation along the harness run
- Loose, corroded or heat-damaged connector plugs at the PCB or component end
- Faults that appear or disappear when the harness and its plugs are disturbed
Before you order
- Check the model and GC number on the appliance data badge against the compatibility list
- Cross-reference the alternative number 1777722 when working from older documentation
- Confirm the connector layout and plug count match the harness being removed
