Baxi 7690388 PCB Kit C33 | Duo-Tec, Platinum & 33kW HE Boilers
The Baxi 7690388 PCB kit C33 LMU34C 6E is a genuine manufacturer printed circuit board designed for selected 33kW high-efficiency combi boilers. The PCB is the boiler’s main electronic control unit and manages ignition, flame supervision, pump operation, temperature regulation, and all critical safety functions.
When a PCB fails, boilers may suffer from lockouts, no heating or hot water, intermittent faults, or persistent error codes. Replacing the faulty unit with the Baxi 7690388 PCB restores stable boiler control and reliable performance.
