Baxi 5106567 Electrode Fan Harness

The Baxi 5106567 is an electrode fan harness assembly manufactured by Baxi for use in its domestic boiler range. It is the wiring assembly that connects the fan and the ignition electrode circuit, carrying the electrical supply and signal path between the two components inside the appliance casing. It is supplied as a single assembly rather than as loose cable and terminals.

• The fan fails to run, or runs intermittently, with no obvious mechanical fault in the fan itself
• Ignition faults or repeated lockouts that trace back to the electrode circuit rather than the electrode or lead
• Visible damage to the harness: chafed, brittle or heat-hardened insulation, exposed conductor, or a cracked plug body
• Loose or corroded terminals at the fan or electrode connection, causing an intermittent open circuit
• Fault codes or diagnostic readings that point to a break in continuity across the fan or electrode wiring

• Confirm the part number 5106567 against the label or data plate on the appliance, and check any GC number shown there
• Compare the connector layout and lead lengths of the old harness with the replacement before fitting, as routing differs between appliance variants
• Check whether any gasket or seal disturbed during access needs replacing at the same time
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
