What it is
The cable tree combustion wiring harness is a Glow-worm wiring component that carries the combustion circuit connections within the boiler. It is used across the BG330 PLUS, Flexicom and Ultimate appliance families. The harness provides the plug-in loom between the combustion-related components and the boiler control.
Signs this part needs replacing
- Combustion circuit faults or intermittent ignition and flame detection errors traced to the harness
- Damaged, chafed or heat-affected insulation on the loom
- Cracked, corroded or loose connector plugs at the harness ends
- Continuity faults or open circuits on individual harness conductors
- Harness connectors that will not latch securely to their mating terminals
Before you order
- Confirm the boiler model and GC number against the fitment list above
- Check the existing harness part number or marking on the component being replaced
- Inspect the connector plugs and pin count to confirm the harness matches the boiler's combustion circuit
- Verify the fault is in the harness rather than the connected components before ordering
