What it is
The IGNITION CABLE is a Worcester Bosch ignition lead used on Greenstar 1000 Series Gr1000W combi boilers. It carries the high-voltage spark from the ignition transformer or PCB to the electrode at the burner, so the gas/air mixture can be lit on demand. The cable is supplied as a single lead for service and repair of the ignition circuit.
Signs this part needs replacing
- Boiler fails to ignite, with no spark at the electrode
- Repeated lockout on start-up or during a demand for heat
- Visible damage to the lead: cracked insulation, scorching, or a broken/corroded terminal
- Intermittent ignition that clears after the cable or connector is disturbed
Before you order
- Confirm the boiler model and GC number against the fit list above
- Inspect the existing lead and electrode terminal for damage before ordering
- Check that the ignition fault is not caused by the electrode, its gap, or the ignition transformer/PCB
- Isolate the appliance and follow the manufacturer's service instructions when fitting
