Worcester 7736700599 Ignition Transformer – Genuine Boiler Igniter
SKU: WRC-IGN-0599-N
The Worcester 7736700599 Ignition Transformer is a genuine replacement component that generates the high-voltage spark required to ignite the boiler burner safely and reliably.
A worn or failed ignition transformer may cause ignition failure, repeated boiler lockouts or ignition-related fault codes. Replacing it with the correct Worcester Bosch OEM part can help restore consistent ignition performance and safe boiler operation.
This component is compatible with selected Worcester Greenstar Life, Greenstar 8000 Life, Greenstar 8000 Style, Greenstar i ErP and GR4700IW boilers, including both natural gas and LPG models.
