Baxi 5112380 PCB – Refurbished
The Baxi 5112380 PCB is a refurbished printed circuit board used across a wide selection of Baxi, Main and Potterton boilers.
The same manufacturer part number appears across several appliance families, including Baxi Combi and System boilers, Main HE models and Potterton Performa appliances.
The PCB acts as one of the boiler’s main electronic control components. It processes signals from sensors and manages several operating functions during heating and hot water demand.
Each refurbished board is professionally inspected and tested before dispatch.
