What it is
The 87161421260 is Worcester's spark generator, built by Vernitron (model 60024-005). It produces the high-voltage pulse sent to the ignition electrode to light the burner on demand.
Signs this part needs replacing
- Boiler fails to spark or ignite when calling for heat or hot water
- Intermittent or weak sparking at the electrode
- Audible clicking from the generator with no visible spark
- Boiler locks out repeatedly on an ignition fault
Before you order
- Match the part number 87161421260 printed on the existing generator
- Confirm your exact boiler model and gas type (NG/LPG)
- Isolate the electrical and gas supply before removing the old generator
- Fitting must be carried out by a Gas Safe registered engineer
