Worcester 7736700599 Ignition Transformer – Genuine Boiler Igniter

Description

Worcester 7736700599 Ignition Transformer | Greenstar Life & 8000 Boilers

The Worcester 7736700599 ignition transformer is a genuine replacement component responsible for generating the high-voltage spark needed to ignite the burner safely and reliably.

If your boiler is failing to ignite, locking out, or displaying ignition fault codes, a worn or failed ignition transformer is a common cause. Replacing it with the correct Worcester Bosch OEM part restores consistent ignition performance and safe boiler operation.

This ignition transformer is used across a wide range of Worcester Greenstar Life, Greenstar 8000 Life, Greenstar 8000 Style, and GR4700IW boilers, covering both natural gas (NG) and LPG models.

Installation must be carried out by a Gas Safe registered engineer.
