Vokera CN1 Ignition Transformer + FA1 Wiring Harness 20040982

The CN1 ignition transformer with FA1 wiring harness is a Vokera component used on Verve series gas boilers. The transformer generates the high-voltage spark that arcs across the ignition electrode to light the burner, and the supplied FA1 harness carries the low-voltage supply and signal connections between the transformer and the boiler's control circuit. It is a service part for the ignition side of the appliance.

• Boiler attempts to fire but there is no spark at the ignition electrode
• Repeated ignition lockouts or failed ignition attempts on start-up
• Intermittent lighting, with the boiler firing on some attempts and not others
• Visible damage to the transformer body, such as cracking, scorching or a burnt smell
• Heat damage, brittle insulation or loose terminals on the FA1 harness

• Confirm the boiler model and GC number against the manufacturer's parts list
• Check the existing transformer and harness connectors for damage before replacing
• Verify the part number 20040982 matches the component fitted to the appliance
• Inspect the ignition electrode and leads, as a fault there can mimic a transformer failure
