Ideal Wiring Harness CUI To Primary Vogue 176924

The Ideal 176924 is a wiring harness that runs between the CUI and the primary on Ideal Vogue boilers. It carries the low-voltage control and signal connections between these two points, so the appliance can regulate and report its operation correctly. The harness is supplied as a complete lead assembly with its connectors fitted, ready to be routed and plugged in during a repair.

• Intermittent lockouts or fault codes that clear when the harness or its plugs are disturbed
• The boiler failing to fire or dropping out mid-cycle with no obvious mechanical cause
• Visible damage to the lead: chafed insulation, scorching, or a connector that has come loose from its terminal
• Corrosion or arcing marks on the plug ends where they meet the CUI or primary connections
• Control or display behaviour that becomes erratic as the appliance warms up and the harness moves

• Confirm the boiler model and GC number against the compatibility list, as the harness is specific to the Vogue C and S ranges
• Check the existing harness part number on the lead or in the appliance documentation, and note the alternative number 1782543
• Inspect the mating connectors on the CUI and primary before fitting, as a damaged socket will not be cured by a new lead
