Description

Baxi 7690350 PCB Kit | Duo-Tec, Platinum & Potterton 28 Combi

The Baxi 7690350 PCB kit Combi 28 HE is a genuine manufacturer replacement printed circuit board used in a wide range of Baxi and Potterton 28kW combi boilers. The PCB is the boiler’s main electronic control unit, responsible for ignition control, flame supervision, pump operation, temperature regulation, and safety monitoring.

When a PCB begins to fail, common symptoms include boiler lockouts, no heating or hot water, intermittent faults, or persistent error codes. Replacing the faulty board with the Baxi 7690350 PCB restores reliable operation and ensures the boiler functions safely and efficiently.

This PCB kit is manufactured to OEM specifications and supplied as a direct replacement for compatible appliances. Installation and commissioning must always be carried out by a Gas Safe registered engineer, and compatibility should be confirmed using the boiler model, issue number, and serial range.
