Description
Baxi Main Potterton 7688421 Boiler PCB Control Board Kit
The Baxi 7688421 boiler PCB kit is a genuine, brand-new replacement control board for selected Baxi, Main and Potterton combi and system boilers.
A boiler PCB, also known as a printed circuit board or control board, manages several important boiler functions. For example, it receives signals from boiler components and controls the operating sequence. Therefore, a faulty PCB may cause ignition problems, intermittent operation, error codes or a complete boiler lockout.
This genuine replacement kit fits several popular Baxi 600 and 800 Series boilers. In addition, it is compatible with selected Main Eco Compact and Potterton combi and system appliances.
Because boiler PCBs may look similar, always check manufacturer part number 7688421, the complete boiler model and the GC number before ordering.
