Ideal Fan Wiring Harness Super 4 100608

The Ideal 100608 is a fan wiring harness supplied for Ideal Super 4 appliances. It is the loom that carries power and control signals between the fan assembly and the boiler's control board, so the fan runs when the board calls for it and any feedback signal returns correctly.

Because the harness sits close to the fan and the flue path, it is exposed to heat and vibration throughout the appliance's working life. The connectors and cable sheathing are the parts that typically degrade first.

• The fan does not start when the boiler receives a call for heat, despite the fan itself testing as serviceable.
• Intermittent fan operation, with the appliance locking out and clearing again on reset.
• Fan-related fault codes appearing on the appliance display or diagnostic readout.
• Visible damage to the loom: cracked or brittle insulation, scorched cable, or exposed conductor near the fan housing.
• Loose, corroded or heat-damaged connector pins at either the fan or the board end of the harness.

• Confirm the appliance model and, where available, the serial number against the compatibility list before ordering.
• Check the harness currently fitted against the alternative number 1779119 to make sure you are matching the right loom.
• Isolate the electrical supply and follow the manufacturer's wiring diagram when fitting; the harness carries mains voltage at the fan end.
• Inspect the fan and its mounting for wear at the same time, since a failing fan can damage a replacement harness.
