The Main 7679746 PCB (refurbished) is a genuine OEM printed circuit board used in a range of Main 25kW combi boilers, including Eco Elite and Combi 25 models. The PCB is the boiler’s main electronic control unit and manages ignition, flame supervision, pump operation, temperature regulation, and all essential safety functions.

When a PCB develops a fault, common symptoms include boiler lockouts, no heating or hot water, intermittent operation, or persistent error codes. Replacing the faulty board with this Main 7679746 PCB restores stable boiler control and reliable performance.
