Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
AL52Generic electronic anomalyControl PCB fault: in Beretta, codes 50–59 correspond to "PCB", and in Mynute Green AL52 it appears as a generic electronic anomaly. Check voltages and outputs on the PCB and its fuse F1 (3.15 A) and rule out wiring/sensors; if it persists, the PCB is damaged and must be replaced.
AL55Anomaly due to missing boiler mode configuration (corresponding jumper absent)The configuration jumper on the PCB (JP4/JP7 depending on version) is missing or incorrectly positioned, typical after PCB replacement or handling. Verify without power by opening the inspection cover of electrical parts and check/place the correct jumper according to the manual.
How do I know if this PCB is for my boiler?
Verify the reference 20008307 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Siemens piece (platform LMU84 AD01C).
What is it used for?
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?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
