Description

Baxi 7690352 PCB (Refurbished) | Duo Tec, Platinum & 33kW Boilers

The Baxi 7690352 KIT PCB C33 LMU34C (refurbished) is a genuine manufacturer printed circuit board designed for 33kW Baxi combi boilers, including Duo Tec, Platinum, and ErP models. The PCB is the boiler’s main electronic control unit, responsible for ignition control, flame supervision, pump operation, temperature regulation, and integrated safety monitoring.

A faulty PCB can cause boiler lockouts, intermittent faults, loss of heating or hot water, or persistent error codes. Replacing the defective board with this Baxi 7690352 PCB restores stable boiler operation and reliable performance.
