Ideal Wiring Harness Safety Extra Low Voltage 176639

The Ideal 176639 is a safety extra low voltage wiring harness used in Ideal Logic System appliances. It carries low voltage signals between the control board and the components it monitors, keeping the sensing and switching circuits separated from mains voltage within the appliance.

This harness is supplied as a spare for the Logic System range and is identified by part number 176639, with 1782094 listed as an alternative number.

• Intermittent lockouts or fault codes that clear and return without an obvious mechanical cause.
• Sensors or switches reading erratically, or readings that change when the harness is moved.
• Visible damage to the loom: chafed insulation, a cracked or corroded plug, or a pushed-back terminal.
• The appliance failing to fire or shutting down shortly after start-up when the control board and sensors are otherwise sound.
• Heat damage or discolouration at the connector ends after a long service life.

• Confirm the appliance model and GC number against the compatibility list before ordering, as the harness is specific to the Logic System range.
• Note the alternative number 1782094 when cross-referencing against older documentation or stock records.
• Isolate the electrical supply at the fused spur before removing or refitting the harness, and check the connector seating on reassembly.
• Inspect the loom routing on removal so the replacement follows the same path clear of hot surfaces and sharp edges.
