Baxi 7683441 Low Voltage 24kW Harness

The Baxi 7683441 is a low voltage harness supplied by Baxi for use in its 24kW appliances. It forms part of the internal wiring that carries low-voltage control and sensor signals between components inside the appliance. The harness is a serviceable item, so it can be replaced independently when the original wiring is damaged or a connector fails.

• The appliance fails to fire or drops out intermittently with no obvious fault at the gas or water side.
• Fault codes relating to a sensor, fan or control circuit appear and return after clearing.
• Visible damage to the loom: chafed, brittle or heat-hardened insulation.
• Loose, corroded or discoloured pins in the harness plugs, or a connector that will not latch.
• Continuity faults traced along the harness during a multimeter check.

• Confirm the appliance model and GC number from the data badge, and check that 24kW matches your unit.
• Match the part number 7683441 against the number printed on the existing harness or listed in the appliance's parts documentation.
• Inspect the connectors and any seals disturbed during removal, and renew them if they show signs of wear.
• Work on the appliance internals should be carried out by a competent person, with the electrical supply isolated first.
