How do I know if this PCB is for my boiler?

Verify the reference 057445 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.

The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.

Is the boiler not igniting, locking out, or is the control board unresponsive?

After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.

Which models is it suitable for?

Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.

Installation and recommendations

After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.

What does refurbished mean and what coverage does it have?
